The brief overview of the radioactive waste issues in the ChEZ presented in this article demonstrates that management of radioactive waste resulting from a ...

This study characterizes potential greater-than-Class C low-level radioactive waste streams, estimates the amounts of waste generated, and estimates their radionuclide content and distribution. Several types of low-level radioactive wastes produced by light water reactors were identified in an earlier study as being potential greater-than-Class C low-level waste, including specific activated metal components and certain process wastes in the form of cartridge filters and decontamination resins. Light water reactor operating parameters and current management practices at operating plants were reviewed and used to estimate the amounts of potential greater-than-Class C low-level waste generated per fuel cycle. The amounts of routinely generated activated metal components and process waste were estimated as a function of fuel cycle. Component-specific radionuclide content and distribution was calculated for activated metals components. Empirical data from actual low-level radioactive waste streams were used

A volume reduction process comprises combinations of a freezing eutectic, bulk, indirect crystallization process and a radwaste electrodialysis process. When employed as a liquid radioactive waste management system (LWMS) for light water reactors (LWRs), this process is designed to process liquid low-level radioactive waste (LLW) and to handle the radioactive influent in nuclear power plants (NPPs) prior to release to the environment and disposal of the radioactive material present in the waste streams.

The Illinois Department of Nuclear Safety has characterized the Martinsville Alternative Site (MAS) for a proposed low-level radioactive waste disposal facility. The MAS is located in east-central Illinois approximately 1.6 km (1 mi) north of the city of Martinsville. Geologic investigation of the 5.5-km2 (1380-acre) site revealed a sequence of chiefly Illinoian glacigenic sediments from 6 to 60 m (20-200 ft) thick overlying two major bedrock valleys carved in Pennsylvanian strata. Relatively permeable buried units include basal, preglacial alluvium; a complex of intraglacial and subglacial sediment; englacial deposits; and supraglacial fluvial deposits. Postglacial alluvium underlies stream valleys on and adjacent to the site. In most areas, the buried sand units are confined by low-permeability till, lacustrine sediment, colluvium, and loess. The distribution and thickness of the most extensive and continuous buried sand units have been modified considerably by subglacial erosion, and their

The Mining and Chemical Combine (MCC), located approximately 60 km north of the city of Krasnoyarsk,is one of two major sites in the Russian Federation where liquid radioactive wastes (LRW) are disposed of by deep well injection. Disposal of LRW at the MCC through the use of deep well injectio started in 1967. The Severny (Northern) site, approximately 15 km north of the MCC, was launched after the completion of special geological surveys and explorations performed by istitutions of the Ministry of Geology and Russian Academy of Sciences. The site was designed by Mintom institutions. As of 1995, 5 million cubic meters (m3) of LRW had been injected into two deep aquifers at the site. The waste includes both radioactive fission products and nonradioactive chemicas used in reprocessing of spent fuel. The total activity, decay corrected to 1995, is approximately 250 million Curies (Ci). Detailed information about radioactive waste disposal at the Severny site is presented in Volume I of this ...

Fort Worth Star-Telegram. Thirty-six states could start shipping loads of radioactive waste through Texas for more than a decade - likely crisscrossing the Metroplex on major highways and train tracks - if they get approval this summer to send their contaminated materials to a West Texas disposal site.. The proposal to allow the states to send low-level waste to a site in Andrews County has prompted concern from some state lawmakers, who worry about the safety of communities along travel routes - including the Interstate 20 corridor through North Texas - and from environmentalists, who worry about radioactive leakage and contamination at the site.. An eight-member commission is expected to take up the issue in coming weeks, considering rules that would govern what materials are accepted and whether dozens of states should be allowed to send radioactive waste to the Waste Control Specialists Texas site owned by Dallas billionaire Harold Simmons.. This could open [Texas] up to not only become ...

A repository for disposal of low-level radioactive waste in Andrews County, west Texas is being constructed within the low-permeable Triassic Dockum Group mudstones (Cooper Canyon Formation) with sparse siltstone/sandstone interbeds. Radionuclides in the repository can be leached out from the repository and eventually migrate downward to a sandstone layer of the Dockum Group, at depth of ~42 meters beneath the repository. Since groundwater in the sandstone layer may be explored for potential domestic use in future, it is of great interest to assess breakthrough of radionuclides which migrate from the repository. A 1D model was constructed for simulating downward migration of four radionuclides (I-123, Tc-99, C-14, and Cl-36) for a time period of 100,000 years. Radionuclide transport in the 1D vertical domain is assumed to be dominated by processes of diffusion, advection, decay and adsorption. The 1D model was solved numerically with Modflow-Surfact and HYDRUS and also with an analytical ...

All of the State TCEQ scientists who worked on the permit for the West Texas dump site, owned by Waste Control Specialists (WCS), determined the site to be inadequate because of the possible radioactive contamination of our aquifers and groundwater. Corruption and politics led to the permitting of the site anyways, ignoring the entire TCEQ technical teams recommendation against issuing the permit. 3 TCEQ employees quit ...

Radioactive waste from nuclear power plants, as well as from medical applications, industry and research, has to be isolated from the environment, particularly the habitat of humans, for a very long time. Specialists at PSI have been concerned with the safety issues surrounding safety certification for geological repositories for many years. Research at PSI focusses primarily on the physico-chemical processes inside such storage systems. The aim is to create a realistic description of the risks associated with storage of radioactive waste.

Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant) to the point where it is no longer useful in sustaining a nuclear reaction.. After uranium fuel has been used in a reactor for a while, it is no longer as efficient in splitting its atoms and producing heat to make electricity. It is then called spent nuclear fuel. About one-fourth to one-third of the total fuel load is spent and is removed from the reactor every 12 to 18 months and replaced with fresh fuel. The spent nuclear fuel is high-level radioactive waste.. The NRC regulates all commercial reactors in the United States, including nuclear power plants that produce electricity, and university research reactors. The agency regulates the possession, transportation, storage and disposal of spent fuel produced by the nuclear reactors.. Spent nuclear fuel is highly radioactive and potentially very harmful. Standing near unshielded spent ...

In 1980, Congress passed the Low-Level Radioactive Waste Policy Act. This law encourages states to join in interstate agreements, or compacts, to provide for disposal of commercial low-level radioactive waste. The law and the 1985 act amending it were endorsed by the Governors of the 50 states. Until 1985, representatives of the Governors worked to implement the federal law through a committee of the National Governors Association. After the passage of the Low-Level Radioactive Waste Policy Amendments Act of 1985, representatives of compacts and states established an independent organization to support the objectives of the federal law and compacts: the Low-Level Radioactive Waste Forum.

Authors: M. P. Hardy and C. M. St. John (University of Minnesota), and G. Hocking (Dames & Moore). Geotechnical numerical models capable of predicting the thermomechanical response and groundwater movements around an underground radioactive waste repository are vital to the success of the nuclear waste disposal program. In the absence of directly related engineering experience, the design, risk assessment and licensing procedures of a repository will be reliant on predictions made using such models. This paper reviews models being used to assist in repository design and summarizes the results of a recent parametric study of underground disposal in basaltic rocks. On the basis of preliminary site data, it is concluded that the allowable areal density of heat generating waste will be controlled by the stability of placement rooms and the boreholes in which waste canisters are placed. Regional effects, including thermally induced upward groundwater flow, appear to present less severe ...

a. Disposition of Solid Wastes.. Solid radioactive wastes may be disposed of by burial in the ground, or at sea. In addition, certain items which contain radium such as luminous instrument dials, may be returned to a radium refining company such as the Canadian Uranium and Radium Corporation or the U. S. Radium Corporation, however, if the amounts of such dials do not justify disposition in this manner, they will be disposed of as indicated in the following paragraphs. Waste must be packaged to comply with the regulations of port authorities concerned when moved by water transportation. Personnel transporting waste materials on land and disposing of them at sea must be instructed as to the proper protective measures.. (1) Burial in the Ground.. Burial sites will be located in isolated areas of the installation and in a location identified on appropriate maps. Selection of such sites should be based upon composition of soil, absence of ground water, and the unlikelihood of erosion exposing the ...

SALT4 is a two-dimensional, analytical/displacement-discontinuity code designed to evaluate temperatures, deformation, and stresses associated with underground disposal of radioactive waste in bedded salt. SALT4 takes into account viscoelastic behavior in the pillars adjacent to excavations, transversely isotropic elastic moduli such as those exhibited by bedded or stratified rock, and excavation sequence. SALT4 can be used for parameter sensitivity analyses of two-dimensional, repository-scale, thermal and thermomechanical response in bedded salt during the excavation, operational, and post-closure phases. It is especially useful in evaluating alternative patterns and sequences of excavation or waste canister placement ...

Low-level radioactive waste (LLRW) includes all LLRW arising from the activities associated with nuclear electricity generation, from nuclear research and development, and from the production and use of radioisotopes in medicine, education, research, agriculture and industry. Examples of LLRW are contaminated materials, rags and protective clothing. It also includes contaminated soils and related wastes resulting from the very early operations of Canadas radium industry. LLRW is grouped into two broad categories, as follows:. ...

Officials say no threat posed, but federal safety team continues to investigate. Federal nuclear safety inspectors are investigating a radioactive waste leak at SCE&Gs atomic power plant in Fairfield County.. An estimated 100 gallons of liquid waste spilled at the utilitys V.C. Summer plant, apparently from a pipe that leaked, according to the U.S. Nuclear Regulatory Commission. The discovery was made late last week.. State, federal and SCE&G officials say they have found no signs the material left the SCE&G nuclear plant or posed any threat to the public, but they are continuing to investigate.. Roger Hannah, a spokesman for the NRC, said the spill appears to have been linked to a failing pipe that led to a discharge point at the facility.. Its something were looking at, Hannah said. Anytime you have a leaking pipe, its something you dont want.. Leaking pipes at nuclear plants are under increasing scrutiny nationally in the wake of a recent Associated Press report..

During the course of 2001 work was carried out to develop a comprehensive syllabus for training in radioactive waste management with particular emphasis on waste safety. This was in response to both the situations where increasing numbers of requests were being received for training events on waste safety, and the recognition in the General Conference resolution of the importance of the Agency training efforts in, inter alia, radioactive waste safety. The scope of the reference training material currently under development is focused on general fundamental principles for radioactive waste (RAW) management, safety requirements on predisposal and disposal activities. It has been structured in six main areas (30 modules): General Aspects, Predisposal Management of RAW, Disposal of RAW, Management of Special Waste, Environmental Restoration and IAEA Activities on Safety of Radioactive Waste Management ...

Workers at the Hanford nuclear reservation in Richland have been evacuated or told to take cover indoors after a cave-in of a tunnel containing radioactive material morning.. Workers at the Hanford nuclear reservation in Richland have been evacuated and others have been told to take cover indoors after a tunnel containing radioactive waste caved in Tuesday morning, government officials said.. More than 3,000 workers were initially told to take cover indoors, an Energy Department spokeswoman said, but that number has since increased as a broader area of the site was included in the emergency alert. All staff had been accounted for and there were no reports of injuries, the department said.. There was no indication of a nuclear release, but crews were continuing to survey for contamination, the department said. Crews were hand surveying outer areas around the tunnels for contamination, but closer to the breach were using a remote-controlled device that can do radiological monitoring and take video. ...

A key component of the US energy program is to provide for the safe and permanent isolation of spent nuclear fuel and long-lived radioactive waste produced through programs related to national defense and the generation of electric power by nuclear utilities. To meet this challenge, the US Department of Energy (DOE) has developed a multi-faceted approach to the geologic disposal of long-lived nuclear wastes. Two sites are being developed or studied as current or potential deep geologic repositories for long lived radioactive wastes, the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico and Yucca Mountain, Nevada.

Practical geologic isolation of some radioactive waste in America began 15 years ago at the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico and will continue for several years or even a few decades. By geologically sequestering natural and anthropogenic radionuclides from the easily accessible biosphere, WIPP mitigates and eliminates their legacy impact on our environment. WIPP science, engineering, and practical operating experience demonstrate that geologic isolation is as feasible and effective in America as it has been elsewhere since the 1960s. But that experience also raises questions about the intellectual and scientific foundation of modern radiation protection standards. Those reflect mainly the technological limits of available instrumentation rather than an assessment of the natural range of radiation exposure in time and space and its effects (or the lack thereof) on humans and the environment. A significant factor determining the natural range of exposure to ionizing ...

During the 40s and 50s, radioactive waste from different sources, including a small company in Beverly that processed uranium for the first atomic bombs, was dumped in Massachusetts Bay. Polly Bradley and other members of the local environmental group, Safer Waters in Massachusetts, are worried that as the LNG project moves forward and Excelerate begins to dig into the ocean floor to construct 16.5 miles of pipeline, they may run into some of that long-buried and forgotten waste.

Low levels of the radioactive isotope tritium have been found in two monitoring wells on the Vermont Yankee compound over the last two weeks.. Though the source of the contaminated water has not yet been identified, officials say it could be coming from a new leak, possibly from pipes buried in soil near the radioactive waste treatment building, where radioactive fluids are treated and stored. As part of the new probe, an Entergy hydrogeologist will be sharing data with experts from New Hampshire, Vermont, Massachusetts and the Nuclear Regulatory Commission on Feb. 10.. The two monitoring wells that have tested positive for very low concentrations of tritium (between 1,000 and 9,000 picocuries per liter, well below the EPA standard of 20,000 pc/L) are located 200 feet and 100 feet, respectively, from tritium contamination that was discovered at the nuclear power plant a little more than a year ago.. ...

Plant-based techniques were tested for field-scale evaluation of tritium contamination adjacent to a low-level radioactive waste (LLRW) facility in the Amargosa Desert, Nevada. Objectives were to (i) characterize and map the spatial variability of tritium in plant water, (ii) develop empirical relations to predict and map subsurface contamination from plant-water concentrations, and (iii) gain insight into tritium migration pathways and processes. Plant sampling [creosote bush, Larrea tridentata (Sessé & Moc. ex DC.) Coville] required one-fifth the time of soil water vapor sampling. Plant concentrations were spatially correlated to a separation distance of 380 m; measurement uncertainty accounted for ,0.1% of the total variability in the data. Regression equations based on plant tritium explained 96 and 90% of the variation in root-zone and sub-root-zone soil water vapor concentrations, respectively. The equations were combined with kriged plant-water concentrations to map subsurface ...

The thermal conductivity of host rocks is an important parameter in the design of deep geological disposal of heat-emitting radioactive waste. Due to bedding, heat transfer in sedimentary rocks is affected by their transversally isotropic structure. In this work, an experimental program is run to measure the thermal conductivities of Boom Clay along various orientations with respect to the bedding plane by using the needle thermal probe technique. Measurements were performed on specimens obtained from cores drilled from the HADES Underground Research Laboratory (URL) at Mol, Belgium, at a depth of 223 m. The thermal conductivity values obtained are in good agreement with those previously published, confirming the thermal anisotropy of Boom Clay. Moreover, the observed changes in thermal conductivity with respect to the distance to the gallery provide further evidence on the extent of the Excavation Damaged Zone around the gallery.

Heres the latest of our news bulletins from the ongoing crisis at Japans Fukushima Daiichi nuclear power plant.. Decontamination Scandal. A major scandal involving shoddy decontamination practices in Fukushima Prefecture is continuing to unfold. Workers say that no training, impossible deadlines, and a sense that their efforts were useless, as well as direct orders from supervisors, led to the improper disposal practices.. In response to a scathing ten-part expose by the Asahi Shimbun, which revealed illegal dumping of radioactive waste into rivers and forests, failure to collect contaminated water used in the cleanup process, and inappropriate use of high-pressured sprayers, Ministry officials finally interviewed supervisors from four contracting firms that had been awarded a highly lucrative 650 billion yen ($7.4 billion) contract. The firms originally agreed to bag all radioactive material, including leaves and branches; only use high-pressure sprayers on gutters and collect all water used; ...

To determine the long-term success of the recommended Yucca Mountain high-level nuclear waste repository, studies of bacterial colonization and biofilm development are needed. Bacteria involved in microbially-influenced corrosion and degradation are known to form biofilms with the potential to impact the integrity of repository packaging and structural materials. Temperature and humidity are environmental factors that can greatly affect biofilm formation. Therefore, it is necessary to determine the temperature and humidity conditions that affect biofilm formation. Microcosms, which simulated the repository environment of Yucca Mountain, were placed at temperatures ranging from 30° C to 70° C and in relative humidities ranging from 100% to 32%. The microcosms contained titanium, C22 nickel alloy, and N316 stainless steel coupons buried in crushed Yucca Mountain muckpile rock. The uniform-sized metal coupons were sacrificed at the following timepoints: day 0, 1 day, 1 month, 5 months,! year, and 18

The uranium refining and conversion plant (URCP) at Ningyo-toge was constructed in 1981 for the purpose of demonstrating on refining and conversion process from yellow cake (or uranium trioxide) to uranium hexafluoride by way of uranium tetrafluoride. For 20 years, 385 tons of natural uranium hexafluoride and 336 tons of reprocessed uranium hexafluoride (approximately) was produced. There are two different type of refining processes in the URCP. One is the wet process by convertig the natural uranium and the other is the dry conversion process for the reprocessed uranium. The dismantling of the dry process facilities began in March, 2008. It was found the large amount of uranium residuals such as wet slurry and powder uranium inside the vessels and pipes. Therefore, we have to take care of the spread of the contamination during dismantling works. The basic strategy concerning plant dismantling were the optimization of the total labor costs and the minimization of the radioactive wastes ...

RICHLAND, Wash. (AP) - Workers have finished stabilizing a second tunnel containing radioactive wastes on the Hanford Nuclear Reservation.. The U.S. Department of Energy announced Monday it had completed filling the tunnel with engineered grout, reducing the risk of a collapse and possible release of radioactive materials.. A federal contractor began grouting the tunnel next to the Plutonium Uranium Extraction Facility last October.. Crews placed the last truckload of grout on Friday.. The tunnel contains 28 railcars holding contaminated equipment and materials generated when Hanford made plutonium for nuclear weapons.. The decision to grout Tunnel 2 was made after the partial collapse of an adjacent waste storage tunnel, known as Tunnel 1, in 2017.. Hanford is located near Richland, Washington, and for decades made most of the plutonium in the nations nuclear arsenal.. ...

More than 120 people converged on the doorstep of the Global Uranium Conference, throwing dyed yellow sand - representing yellow cake or uranium concentrate - and demanding BHPs proposed $17 million Yeelirrie mine be scrapped.. Ban Uranium Mining Permanently campaigner Kate Vallentine said the protesters want to make it clear that uranium is too dangerous, too dirty and too risky.. The WA public has been left out in the cold while government and industry have taken it upon themselves to bulldoze over public opinion at the largest uranium conference in Australia, Ms Vallentine said.

Cattleman George Glasier sees the next nuclear era amid the blood-orange mesas of Paradox Valley, the same Western range lands that hold a darker legacy from the last rush to pull uranium from the ground. The land is not far from the toxic uranium mines, now mostly abandoned, that serve as a reminder of an industry born of the Cold War. Industry officials say new technology such as enclosed radioactive waste containers has made processing safer than in the past. Uranium miners have suffered from lung cancer, pulmonary fibrosis and pneumoconiosis, a lung disease from inhaling dust. The same fight is brewing across the country as residents and environmental groups try to block new mines and processing facilities for the nuclear industry. The first application since 1988 for a uranium processing facility was filed in October with the Nuclear Regulatory Commission. [...] the NRC has received 27 applications for facilities in Wyoming, Nebraska, South Dakota, Arizona and New Mexico. In the other form

The effects of the addition of divalent metal oxides on the structure and thermophysical properties of the mixed alkali borosilicate glass system used for high level radioactive waste immobilisation have been studied. Densities, molar volumes, linear thermal expansivities and glass transition temperatures are reported and structural information has been obtained using B-11 and Si-29 magic angle spinning (MAS) NMR. Molar volume is controlled by ion size and by the formation of network polyhedra, whilst thermal expansion reflects the network rigidity. Changes in the glass transition temperature, T-S, are consistent with the different values of the heat of formation of the oxides added. Alkaline earth oxides produce an initial increase in the fraction of 4-coordinated boron, N-4, whereas PbO and ZnO reduce N-4. Si-29 NMR of the alkaline earth oxide glasses shows the presence of significant concentrations of nonbridging oxygens, consistent with a previous study of the aqueous corrosion behaviour of ...

A number of geodisposal concepts for intermediate level radioactive waste involve geological emplacement within cementitious repositories. Such facilities, once rehydrated with groundwater, will create high pH environments due to aqueous phase reaction of the cements. This work focuses on the interactions of several important long-lived radionuclide cations with dissolved organic matter (DOM) constituents (humic and fulvic acids) under high pH conditions. We also sought to test the comprehensive speciation model WHAM/Humic Ion Binding Model VII for these specific conditions. Results for Th demonstrate high fractions present as organic complexes at all pH values. Binding of neptunyl to DOM shows a maximum over the pH range expected within an evolving repository. Uranyl exhibits decreasing binding with pH, however, the majority of metal in solution is present as organic complexes under the lower pH conditions investigated (10-10.5). We have updated the WHAM/ Model VII binding values for UO2þ2 , ...

What is background radiation?. Ionising radiation always present in the environment. Why does background radiation not cause harm?. The levels are constant and are too low to be harmful and are naturally occuring mostly. Main contributors to background radiation?. Cosmic rays from the sun, decay of rocks, radon gas from the ground. Small contributors to background radiation?. Man made sources like radioactive waste from nuclear power stations and hospitals, and from smoke alarms. How much does human activity contribute to background radiation?. Less than 1%. What is the most common radioisotope used in smoke alarms?. Americium 241. What type of radiation do smoke alarms give out?. Alpha. How does a smoke alarm work?. The alpha particles ionise the molecules of the air forming ions and electrons which are attracted to a pair of charged plates as shown in the picture below. When the ions and electrons hit the plates they provide a small amount of electricity (a small current). This current stays ...

Amy: Iraq is a horrible killing field. During Gulf War I in 1991, the U.S. military used 350 tons of uranium weaponry in Iraq. This likely explains why 325,000 Gulf War I vets are now on permanent medical disability. Then, in 2003 when the U.S. invaded Iraq again, both the Pentagon and the United Nations admitted that coalition forces used another 2,200 tons in March and April of that year alone. So, at that point, Iraq--only 2/3 the size of Texas--was drenched in 2,500 tons of radioactive waste. According to calculations by the United Kingdom Atomic Energy Authority, thats enough radiation to generate over 20 million new cancers, or a case of cancer for about every citizen in Iraq. But the war and occupation have been roaring on for an additional two years and no one has yet calculated how many additional tons have been used against the insurgency and the civilian population since the invasion. Wherever our troops fight rebellious Iraqis, they use uranium weaponry, contaminating themselves and ...

West Lake Landfill is a closed, unlined mixed-waste landfill located in Bridgeton, Missouri. Its contents have been shown to include radioactive waste; it is thus also an EPA Superfund cleanup site. The West Lake Landfill site originated in 1939 as a limestone quarry operated by the Westlake Quarry Company. Landfilling at the site began in the 1950s. In 1973, after having changed hands (and responsible oversight) several times, B&K Construction Co., a company contracted by Cotter Corporation, dumped a portion of the original stored radioactive material at a nearby storage facility. 8,700 short tons (7,900 t) of leached barium sulfate, the material with the lowest relative radioactivity, was combined with 39,000 short tons (35,000 t) of topsoil to dilute the contaminated material at the landfill. The leached barium sulfate was a byproduct of Mallinckrodt Chemical Works uranium enrichment program as a part of the Manhattan Project and later nuclear weapons production. and dumping it there was ...

Tritium is usually measured by using a liquid scintillation counter. However, liquid scintillator used for measurement will become radioactive waste fluid. To solve this issue, we have developed a method of measuring tritium samples with plasma-treated plastic scintillator (PS)sheets (Plasma method). The radioactive sample is held between 2 PS sheets and the whole is enclosed in a a low-potassium glass vial. With the Plasma method of 2-min plasma treatment, we have obtained measurement efficiency of 48 ± 2 % for 2 min measurement of tritium except for tritiated water. The plasma treatment makes the PS surface rough and hydrophilic which contributes to improve the contact between tritium and PS. On the other hand, it needed almost 6 hours to obtain constant measurement efficiency. The reason was that the dry-up handling in the vial needed longer time to vaporize H{sub 2}O molecules than in the air. We tried putting silica gel beads into vials to remove H{sub 2}O molecules from PS sheet surface ...

Yucca Mountain, in southern Nevada, is being investigated by the U.S. Department of Energy as a potential site for a repository for high-level radioactive waste. This report documents the results of surface-based geologic, pneumatic, hydrologic, and geochemical studies conducted during 1992 to 1996 by the U.S. Geological Survey in the vicinity of the North Ramp of the Exploratory Studies Facility (ESF) that are pertinent to understanding multiphase fluid flow within the deep unsaturated zone. Detailed stratigraphic and structural characteristics of the study area provided the hydrogeologic framework for these investigations. Multiple lines of evidence indicate that gas flow and liquid flow within the welded tuffs of the unsaturated zone occur primarily through fractures. Fracture densities are highest in the Tiva Canyon welded (TCw) and Topopah Spring welded (TSw) hydrogeologic units. Although fracture density is much lower in the intervening nonwelded and bedded tuffs of the Paintbrush nonwelded

Iodine 129 is a radioactive waste produced by the nuclear industry. Due to its high volatility, it cannot be vitrified in conventional borosilicate glasses. This paper investigates the feasibility of iodine conditioning using a glass matrix intended for long-term storage in a geological repository. Silver phosphate glasses, which can incorporate high amounts of iodine and can be synthesized at low temperature, were chosen for this study. In order to increase their chemical durability, the glasses were cross-linked by niobium and bismuth oxides. Niobium and bismuth incorporation limits were determined for an iodine amount of 12 wt% and ranged from 1.6 mol% to 4.0 mol%, depending on the Ag2O/P2O5 ratio. The glass structures were investigated using 31P MAS NMR, RAMAN spectroscopy and X-ray absorption spectroscopy. The iodine local environment was determined by EXAFS at iodine K-edge. Structural investigations showed that the introduction of these crosslinking reagents induces a significant increase in the

The nuclear fission is generally considered as a dangerous energy due to its contaminant risks of radioactive waste resulting from the electricity generation process. The past events occurred in Japan after the tsunami of 2011 increased the risk perception of this type of energy generation what has provoked that research on alternative ways to obtain energy have gained more importance than ever.. For years, nuclear fusion was studied as an alternative to nuclear fission because of its remarkable advantages for security and financial issues. However, today, there is not working any fusion reactor to produce continuous electrical energy of high voltage.. As a result of the Project Fusion Power, the Professor González Díez designed a prototype of fusion reactor by inertial confinement, of total conversion of material into energy, whose fusion chamber can adapt to the type of fuel that wishes to be used, specially deuterium-tritium, deuterium- deuterium or hydrogen-hydrogen. Therefore, according ...

If that werent bad enough, Fukushima continues to leak an astounding 300 tons of radioactive waste into the Pacific Ocean every day. It will continue do so indefinitely as the source of the leak cannot be sealed as it is inaccessible to both humans and robots due to extremely high temperatures. It should come as no surprise, then, that Fukushima has contaminated the entire Pacific Ocean in just five years. This could easily be the worst environmental disaster in human history and it is almost never talked about by politicians, establishment scientists, or the news. It is interesting to note that TEPCO is a subsidiary partner with General Electric (also known as GE), one of the largest companies in the world, which has considerable control over numerous news corporations and politicians alike. Could this possibly explain the lack of news coverage Fukushima has received in the last five years? There is also evidence that GE knew about the poor condition of the Fukushima reactors for decades and ...

In argillaceous rocks, which are considered as a potential host rock for nuclear waste repositories, sorption and diffusion processes govern the migration behaviour of actinides like neptunium. For the safety analysis of such a repository, a molecular-level understanding of the transport and retardation phenomena of radioactive contaminants in the host rock is mandatory. The speciation of Np during sorption and diffusion in Opalinus Clay was studied at near neutral pH using a combination of spatially resolved synchrotron radiation techniques. During the sorption and diffusion experiments, the interaction of 8 μM Np(V) solutions with the clay lead to the formation of spots at the clay-water interface with increased Np concentrations as determined by μ-XRF. Several of these spots are correlated with areas of increased Fe concentration. Np L3-edge μ-XANES spectra revealed that up to 85% of the initial Np(V) was reduced to Np(IV). Pyrite could be identified by μ-XRD as a redox-active mineral ...

WISE NC 503.4965; The Dutch Energy Research Foundation (ECN) in Petten organized a workshop on transmutation of nuclear waste on November 13, 1998. The researchers claimed that results are so favorable that further reprocessing and vitrification of nuclear waste better be stopped: if nuclear waste has been reprocessed and vitrified, transmutation is not possible any longer.

6 Aquifers: Our groundwater storage units Water and contaminants can move quickly through cracks and fractures. Aquifers are geologic formations that store and transmit groundwater. The aquifer properties determine how quickly groundwater flows, how much water an aquifer can hold and how easily groundwater can become contaminated. Some aquifers may also contain naturally occurring elements that make water unsafe. Wisconsins geology is like a layered cake. Underneath all of Wisconsin lies the Crystalline bedrock which does not hold much water. Think of this layer like the foundation of your house. All groundwater sits on top of this foundation. Groundwater is stored in the various sandstone, dolomite and sand/gravel aquifers above the crystalline bedrock layer. The layers are arranged in the order which they formed, oldest on the bottom and youngest on top.

A team of researchers from the University of South Carolina is using neutrons to develop more durable and efficient materials called waste forms for safely storing hazardous substances.. The USC team recently visited the Department of Energys Oak Ridge National Laboratory to study salt-inclusion materials (SIMs) that contain internal silicate channels with the capacity to safely immobilize nuclear waste. The researchers hope to obtain valuable insights into the materials properties using resources at ORNLs Spallation Neutron Source such as the POWGEN instrument, SNS beamline 11A. We are studying SIMs with the intent to create new materials that more efficiently and safely sequester nuclear waste elements like technetium, said principal investigator Hans-Conrad zur Loye. This is a long-term process, and we hope to develop the fundamental chemistry needed to design these waste forms over the next several years.. Waste form materials act as a sort of crystalline bag to contain radioactive ...

This attractive book presents the role of nuclear power in providing energy to meet current and future global demands. Its chapters address current and future energy use; the generation of electricity; nuclear power; the front end of the nuclear fuel cycle (mining, milling, enrichment, and current reactor technology); the back end of the cycle (waste reprocessing, storage, and disposal); other applications of nuclear energy (hydrogen generation, desalination, production of radioisotopes, and marine propulsion); issues associated with the environment, health, and safety; the avoidance of proliferation; and the history of nuclear energy. A clear, reasonably balanced narrative combined with numerous diagrams and tables make the book an excellent choice for an introduction to nuclear power. Seven previous editions of the book were titled Nuclear Electricity; the full text of the seventh, published in 2003, is available online.. ...

The two new atoms are called daughters. One typical daughter product is Xenon 135. Xenon is not the sister of a mythical warrior princess. Xenon is a colorless, heavy gas, that is chemically inactive. Xenon 135 is produced as a byproduct of nuclear fission in reactors and is notorious among nuclear scientist because it poisons nuclear chain reactions. Xenon 135 is very radioactive, but this also means that it has a short half life. In fact the half life of Xenon 135 is a little over 9 hours, and decays into Caesium 135. Caesium 135 is weakly radioactive. It has a half life, of 2.3 million years, and then it decays by releasing a weak beta particle, and is transformed into barium 135. Barium 135 is stable. Because other, more dangerous, isotopes of Caesium are produced in chain reactions, Caesium 135 comming out of nuclear fuel is a candidate for long term disposal ...

Sometimes things just naturally come full circle.. For decades Nevadas former U.S. Sen. Harry Reid constantly pounded on two themes: Blocking nuclear waste from being stored in Yucca Mountain in Nye County and pressing for more and more solar panels to be thrown up on thousands of acres of public land and on rooftops across the state.. When Congress designated Yucca Mountain as the nations sole nuclear waste dump in 1987, Reid said two things, no and hell no. As he rose in seniority in the Democratic Party to become Senate majority leader, he finally found the power to make those words stick and steadily turned down the funding spigot for the project until President Obama shut it down entirely.. As he neared retirement, Reid declared Yucca Mountain dead, though President Trump and his Energy Secretary Rick Perry have been trying to breathe life back into it.. Meanwhile, Reid campaigned vigorously for green energy, bragging about his role in the state investing $6 billion in green energy and ...

WASHINGTON U.S. Senate Majority Leader Trent Lott (R-MI) today failed in his plan to file a motion to invoke cloture in the U.S. Senate in his first formal attempt to bring S. 1287, the Nuclear Waste Amendments Act of 1999, to the floor of the U.S. Senate for consideration. Majority Leader Lott backed off of his effort to file cloture after U.S. Senator Richard Bryan (D-NV) warned the Majority Leader that he would not allow the Senate to consider the Bankruptcy bill or any other legislation once a cloture motion for the nuclear waste bill was invoked. While Senator Lott failed to file cloture today, it is expected that he may file the motion at some point next week. However, with the Senate calendar for the year quickly coming to a conclusion, with an expected adjournment date within the next several weeks, the remaining time for the consideration of this misguided legislation is quickly slipping away.. This was our closest call yet for the year, Senator Bryan stated. Every day that the ...

We Japanese civil organizations express our deepest concern that our government does not inform its citizens about the extent of risk of the Fukushima Daiichi Unit 4 spent nuclear fuel pool. Given the fact that collapse of this pool could potentially lead to catastrophic consequences with worldwide implications, what the Japanese government should be doing as a responsible member of the international community is to avoid any further disaster by mobilizing all the wisdom and the means available in order to stabilize this spent nuclear fuel. It is clearly evident that Fukushima Daiichi Unit 4 spent nuclear fuel pool is no longer a Japanese issue but an international issue with potentially serious consequences. Therefore, it is imperative for the Japanese government and the international community to work together on this crisis before it becomes too late. We are appealing to the United Nations to help Japan and the planet in order to prevent the irreversible consequences of a catastrophe that ...

With the introduction of modern medical practice the biomedical wastes would get piled up in coming times. The condition that Kashmir valley is going through demands special attention to this problem. In normalcy if the hospitals generate such a huge percentage of these wastes what should be the level of the production of such waste in the present day circumstance. It has been estimated that there will be a growth of 8% of such waste annually in peaceful atmosphere assuming that each bed of the hospital generates about 2 kgs of such wastes. Is the government of Jammu and Kashmir ready to face the worst situation? Infact there has developed a relationship of hatred between the Municipal authorities and the people residing near the dumping site, what will happen if it spreads to other areas.

05 December 2012. Back in 2000, when Kirk Sorensen was a NASA engineer looking at nuclear-power options for future colonies on the Moon, he came across a book that described the molten-salt reactor: an energy source in which the nuclear fuel was liquid.. It sounded bizarre, says Sorensen. Every reactor he had ever heard of used some form of solid uranium fuel - starting with the light-water reactors that currently dominate the nuclear-power industry. But the book explained that the molten-salt technology had been demonstrated some three decades earlier at the Oak Ridge National Laboratory in Tennessee - and that the fluid uranium- or thorium-containing fuel offered major advantages. Molten-salt reactors would be impervious to catastrophic meltdown, for example, and instead of producing nuclear waste laced with plutonium and other long-lived radioisotopes, they could destroy those isotopes almost completely.. The list of advantages went on and on, says Sorensen: the molten-salt idea had the ...

Modelling Studies for the Assessment of the Advanced Cold Process Canister. The Advanced Cold Process Canister (ACPC) is a new concept for the encapsulation of spent nuclear fuel for geological disposal. It consists of steel canister encased in a copper overpack. In this paper, modelling studies to assess the performance of the ACPC under repository conditions are presented. The production of nitric acid and ammonia through radiolysis of any water remaining inside the canister under fault conditions has been examined in this study. However, results suggest that only low levels are possible, and the risk of stress-corrosion cracking is considered small. The corrosion behaviour subsequent to a breach in the outer canister was also considered. A model was constructed to predict the hydrogen gas production due to corrosion reactions, and evolution of the corrosion behaviour.
