The main purpose of this project was to advance the basic scientific understanding of colloid and colloid-facilitated Cs transport of radionuclides in the vadose zone. We focused our research on the hydrological and geochemical conditions beneath the leaking waste tanks at the USDOE Hanford reservation. Specific objectives were (1) to determine the lability and thermodynamic stability of colloidal materials, which form after reacting Hanford sediments with simulated Hanford Tank Waste, (2) to characterize the interactions between colloidal particles and contaminants, i.e., Cs and Eu, (3) to determine the potential of Hanford sediments for \textit{in situ} mobilization of colloids, (4) to evaluate colloid-facilitated radionuclide transport through sediments under unsaturated flow, (5) to implement colloid-facilitated contaminant transport mechanisms into a transport model, and (6) to improve conceptual characterization of colloid-contaminant-soil interactions and colloid-facili\-tated transport for clean
It has generally been recognized that molecular diffusion can be a significant process affecting the transport of carbon-14 in the subsurface when occurring either from a permeable aquifer into a confining layer or from a fracture into a rock matrix. An analytical solution that is valid for steady-state radionuclide transport through fractured rock is shown to be applicable to many multilayered aquifer systems. By plotting the ratio of the rate of diffusion to the rate of decay of carbon-14 over the length scales representative of several common hydrogeologic settings, it is demonstrated that diffusion of carbon-14 should often be not only a significant process, but a dominant one relative to decay. An age-correction formula is developed and applied to the Bangkok Basin of Thailand, where a mean carbon-14-based age of 21,000 years was adjusted to 11,000 years to account for diffusion. This formula and its graphical representation should prove useful...
This paper focuses on the radioactive Cs in seawater and summarizes estimates of the total amount of released radioactive Cs from the FNPP site, spatio-temporal changes in the concentrations of 134Cs and 137Cs not only off the coast of Fukushima and adjacent prefectures, but also in the North Pacific, and adjacent seas such as Japan…

This study examined potential microbial impacts of cyanide contamination in an aquifer affected by ferrocyanide disposal from nuclear waste processing at the US Department of Energys Hanford Site in south-eastern Washington State (USA). We examined bacterial productivity and microbial cell density in groundwater (GW) from wells with varying levels of recent and historical total cyanide concentrations. We used tritiated leucine (3H-Leu) uptake as a proxy for heterotrophic, aerobic bacterial productivity in the GW, and we measured cell density via nucleic acid staining followed by epifluorescence microscopy. Bacterial productivity varied widely, both among wells that had high historical and recent total cyanide (CN−) concentrations and among wells that had low total CN− values. Standing microbial biomass varied less, and was generally greater than that observed in a similar study of uranium-contaminated hyporheic-zone groundwater at the Hanford Site. Our results showed no correlation between 3H-Leu
FRAMES 1.7/GENII 2.10 replaces GENII 2.09, which has been distributed by RSICC. The GENII system includes capabilities for calculating radiation doses following chronic and acute releases. Radionuclide transport via air, water, or biological activity may be considered. Air transport options include both puff and plume models, each allowing use of an effective stack height or calculation of plume rise from buoyant or momentum effects (or both). Building wake effects can be included in acute atmospheric release scenarios. The code provides risk estimates for health effects to individuals or populations; these can be obtained using the code by applying appropriate risk factors to the effective dose equivalent or organ dose. In addition, GENII Version 2 uses cancer risk factors from Federal Guidance Report 13 to estimate risk to specific organs or tissues. Although the codes were initially developed at Hanford, they were designed with the flexibility to accommodate input parameters for a wide ...
In 1943, the US government needed a reliable center for processing the Manhattan Projects nuclear material. Officials chose the 568-acre Hanford site in the deserts of Washington State to house nine nuclear reactors and 143 single-walled, underground waste tanks. Fast-forward 68 years and the US government is still working at Hanford - not as a research facility, but as one of the countrys most polluted Superfund sites.
February 3, 2017.. The REDOX Complex, comprised of the 202S building and surrounding structures, was used for chemical separation of plutonium from irradiated fuel rods from 1952 through 1967. A limited shut-down of REDOX was performed after operations ceased, and the facility is currently in Surveillance and Maintenance (S&M) mode awaiting a final Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) cleanup decision. DOE-RL recommends a removal action be performed prior to the final cleanup to mitigate potential threats to human health and the environment posed by contamination in the area. DOE-RL proposes to address hazards through a variety of actions including removing legacy waste, performing hazard abatement activities inside the 202S Building, and demolishing the 293S Building along with the annex portions of the 202S Building. These actions would reduce the potential threats of contamination by allowing workers access to clean up radioactive and hazardous ...

RICHLAND, Wash.-The U.S. Department of Energy has given the state of Washington a plan for emptying a leaking nuclear waste storage tank at the Hanford Nuclear Reservation. The Tri-City Herald reports (http://is.gd/fIi6tP) that while the Energy Department will start buying equipment and making other plans to remove the radioactive sludge from the double-shell tank with a leak between its shells, actual waste pumping would start no sooner than March 2016. The plan for emptying Tank AY-102 was given to the state near the close of business Friday. The state has not yet reviewed the plan to comment on it. The newspaper says DOE already has equipment in place to remove liquid waste from the tank. But according to the plan, no waste would be pumped until the department is ready to proceed with liquid and sludge removal. No waste is believed to have escaped into the soil beneath the tank. Hanford authorities have known the tank was leaking for about a year. State officials have urged the Energy ...
Life first stirred at the Department of Energys Hanford Site in Richland, Wash., in 1943. The mission of the site was to produce plutonium for the worlds first atomic weapons. It was known worldwide as the birthplace of the Fat Man bomb which was dropped on Nagasaki. Now it is known as one of the most contaminated places on earth. The current mission at Hanford is waste remediation and environmental
A low temperature waste form known as Cast Stone is being considered to provide supplemental Low Activity Waste (LAW) immobilization capacity for the Hanford site. Formulation of Cast Stone at high sodium concentrations is of interest since a significant reduction in the necessary volume of Cast Stone and subsequent disposal costs could be achieved if an acceptable waste form can be produced with a high sodium molarity salt solution combined with a high water to premix (or dry blend) ratio. The objectives of this study were to evaluate the factors involved with increasing the sodium concentration in Cast Stone, including production and performance properties and the retention and release of specific components of interest. Three factors were identified for the experimental matrix: the concentration of sodium in the simulated salt solution, the water to premix ratio, and the blast furnace slag portion of the premix. The salt solution simulants used in this study were formulated to represent the ...
Radionuclides of the naturally occurring decay chains of uranium-238, uranium-235 and thorium-232 are present in traces in all rocks and mineral ores. So when using raw materials like rocks and mineral ores, natural radionuclides are generally introduced unintentionally into industrial processes. In some branches of industry, natural radionuclides can accumulate in parts of the material flux. In specialist literature, these residues are often referred to as "naturally occurring radioactive materials" ("NORM" for short).. ...
A]t this current time in July of 2013, ***ushima is 80 to 100x more expansive and more intense - letting out about 100x more of the radiation of Chernobyl. The problem with ***ushima is that its not only continuing for 865 days… I mean, lets wrap our minds around that for a second - it has been leaking out radiation in increasing volumes for 865 days. Thats two years, four months, 12 days to be precise - since 3/11/11. And its coming in the air. Its all over the Pacific. And what we have to do is -weve been charting the progress of this - how its been affecting stillbirths - and the Canadian government let out some studies saying that it found stillbirths along the British Columbia coastline that are 800% -- year over year - increased since 2011 ...
Writing for the Portland Independent Media Centre on 3 July 2005, he declares: "Health physicists are deeply concerned with the public health and welfare, and as experts in radiation and its effects on people and the environment, are quite aware that something other than exposure to uranium is the cause of the illnesses suffered by those who have had contact with depleted uranium from munitions. A truly enormous body of scientific data shows that it is virtually impossible for uranium to be the cause of their illnesses. Despite this body of scientific data to the contrary, misguided or unknowing people continue to allege that the depleted uranium, and specifically the radioactivity associated with the depleted uranium is the cause of these illness. This is indeed unfortunate, for health physicists and other scientists and physicians already know that depleted uranium is not the cause of these illnesses and thus any investigations into the cause of these illnesses should focus on other possible ...

However, when depleted uranium explodes upon impact, and burns with high temperature, it becomes micro-particles of oxidized uranium (ceramic form aerosol of diametrical-micron; a micron is equivalent to 1/1000mm), discharged heavily, and are packed in tanks. Also, the particles diffused in the atmosphere and whirled up in the sky, pollute vast range of the atmosphere, and also, the particles that fall on the ground pollute the environment such as the soil and water, etc.. 4. Dreadful Negative Effects of Depleted Uranium Weapons on the Human Body. Once the uranium particles are inhaled into the body, the particles attach first to the trachea and the respiratory system. As the particles are practically insoluble, they are difficult to dissolve in the blood, and stay there for a long period of time. Eventually these clinging particles continue to expose the neighboring organs to radiation. By that, they cause the cell and the gene to go into some transformation, and cause cancers, leukemia, ...
Access to radium-223 dichloride has been restored following a temporary suspension in production by its manufacturer Bayer HealthCare Pharmaceuticals to adjust its manufacturing process to meet certain quality standards that the company has in place.
US uranium concentrate production slumped 89% last year, to 174 000 lb of U3O8, according to information by the US Energy Information Administration (EIA). This is a sharp decrease from the 4.89-million pounds a year that the US produced five years earlier. The EIA report comes about a month after the Trump Administration outlined
This book features scientific research that supports the safe and effective disposal of radioactive waste in a geological repository. One highlight of the volume is the opening talk by Rustum Roy, who was instrumental in establishing the first symposium on this topic in 1978. Professor Roy summarizes his views of the past 19 years of progress in the field. A second highlight is the participation by several Russian and Ukrainian scientists who authored papers on nuclear waste disposal aspects of the Chernobyl Unit 4 reactor that exploded in April 1986. Additional topics include: glass formulations and properties; glass/water interactions; cements in radioactive waste management; ceramic and crystalline waste forms; spent nuclear fuel; waste processing and treatment; radiation effects in ceramics, glasses and nuclear waste materials; waste package materials; radionuclide solubility and speciation; radionuclide sorption; radionuclide transport; repository backfill; performance assessment; natural analogues
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

How do you get rid of hundreds of tons of highly radioactive water? You dump it into the Pacific Ocean of course! In Japan, the Tokyo Electric Power Co. has made the "painful decision" to begin purposely dumping massive amounts of radioactive water currently being stored at the destroyed Fukushima nuclear facility directly into the Pacific. This is being done even though water radiation levels near Fukushima spiked to a brand new all-time record high just a few days ago. The radioactive material that is being released will enter our food chain and will potentially stay with us for decades to come. Fukushima is an environmental nightmare that never seems to end, but the mainstream media in the United States decided to pretty much stop talking about it long ago. So dont expect the big news networks to make a big deal out of the fact that Japan is choosing to use the Pacific Ocean as a toilet for their nuclear waste. But even though they arent talking about it, that doesnt mean that radioactive ...
Solid radioactive waste can be broken down into two categories: waste that contains radioisotopes with half-lives of greater than 90 days, and waste that contains radioisotopes with half-lives of less than 90 days.. Waste containing radioisotopes of half-lives less than 90 days are allowed to decay to background radiation levels before disposal. Waste with half-lives greater than 90 days are either stored or incinerated.. Less than 90 day half-life? See Solid Radioactive Waste Management. Greater than 90 day half-life?

Hospital workers sift through ashes for tiny tubes of radium using a Radium Hound detector 1944. Examples of recovered radium from Dr. Tafts publications are listed below:. Dr. Curtis F. Burnam lost radium tube that was misplaced in hospital dressing. Using the electroscope instrument, the radium was discovered in a city dump.. Dr. Albert Soiland lost 75 mg of radium. The patient slipped away from hospital and deposited radium behind soil pipes in a bathroom. It was located using the electroscope. In a second incident, 2 or 3 mg of radium was discarded with dressing and discovered in the basement of the building.. J. L. Weatherwax lost 50 mg of radium in 1930 and was recovered in an ash pile which had gone through an incinerator using the electroscope. Others were lost which included 10 mg radium in 1931, 200 mg radium applicator in 1932, 140 mg applicator in 1935, 10 mg radium needle in 1935, 8 or 10 mg needles lost but crushed and dispersed, and a 50 mg applicator lost in 1932. These were ...
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.
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 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 ...

Properties. Pure metallic radium is dazzling white after it has been isolated, but as it is exposed to the air it turns black due to oxidation. Radium displays luminescence, emits a red colour when it is exposed to a flame and decomposes when it is placed in water. Radium is similar in its properties (except for its radioactivity) to the alkaline earths - calcium, strontium and barium. It comes from pitchblende an ore of uranium and is separated from it by using similar methods to those of the Curies. Radium emits alpha, beta, and gamma rays and when mixed with beryllium produces neutrons. Inhalation, injection, or body exposure to radium can cause cancer and other body disorders. It has four naturally occurring radioactive isotopes, but others can be produced in the laboratory. Radium has a half-life of 1620 years and the product of its disintegration is, radon, an inert gas disintegrated radioactively until it reaches stable lead. Radium is over a million times more radioactive than the same ...
Radium was formerly used in self-luminous paints for watches, nuclear panels, aircraft switches, clocks, and instrument dials. More than 100 former watch dial painters who used their lips to shape the paintbrush died from the radiation. Soon afterward, the adverse effects of radioactivity became widely known. Radium was still used in dials as late as the 1950s. Although tritiums beta radiation is potentially dangerous if ingested, it has replaced radium in these applications. During the 1930s it was found that workers exposure to radium by handling luminescent paints caused serious health effects which included sores, anemia and bone cancer. This use of radium was stopped soon afterward. This is because radium is treated as calcium by the body, and deposited in the bones, where radioactivity degrades marrow and can mutate bone cells. The litigation and ultimate deaths of five "Radium Girl" employees who had used radium-based luminous paints on the dials of watches and clocks had a significant ...
The chapter on radium in particular sparked my interest. Blum describes in vivid detail the well-known misadventure of the "radium girls", a label given to young women in a watch factory in Orange, NJ, in the early 1920s. She sets up the story with the fascinating background of radium discovery by the Curies and Marie Curies penchant for carrying a "pet" bottle of radium in her skirt pocket, exhibiting its breathtaking beauty in a circus-like fashion (she died a horrible death from aplastic anemia induced by radiation exposure). Once its tumor shrinking properties became known, it did not take long for entrepreneurs, backed by the medical establishment, to create and sell all kinds of tonics and pills containing radium to the clueless public searching for the fountain of youth. The tragic tale of the radium girls, who, because of occupational ingestion of radium used for painting numbers on the faces of watches (according to Blums account, the girls were encouraged to lick the paint brushes to ...
Microbiological reduction of soluble U(VI) to insoluble U(IV) has been proposed as a remediation strategy for uranium-contaminated groundwater. Nitrate is a common co-contaminant with uranium. Nitrate inhibited U(VI) reduction in acetate-amended aquifer sediments collected from a uranium-contaminated site in New Mexico. Once nitrate was depleted, both U(VI) and Fe(III) were reduced concurrently. When nitrate was added to sediments in which U(VI) had been reduced, U(VI) reappeared in solution. Parallel studies with the dissimilatory Fe(III)-, U(VI)- and nitrate-reducing microorganism, Geobacter metallireducens, demonstrated that nitrate inhibited reduction of Fe(III) and U(VI) in cell suspensions of cells that had been grown with nitrate as the electron acceptor, but not in Fe(III)-grown cells. Suspensions of nitrate-grown G. metallireducens oxidized Fe(II) and U(IV) with nitrate as the electron acceptor. U(IV) oxidation was accelerated when Fe(II) was also added, presumably due to the Fe(III) ...
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..
