Fangjiashan Nuclear Power Plant (方家山核电站) is a nuclear power plant in the Zhejiang province, China, adjacent to the existing Qinshan Nuclear Power Plant. Two 1,080 megawatt (MWe) CPR-1000 pressurized water reactors (PWRs) are under construction, at a total cost of 26 billion yuan (US$3.8 billion).[1] First concrete for the first unit at the Fangjiashan plant was poured on 26 December 2008. Construction of the second unit followed in July 2009. The reactors were first connected to the grid December 2014 and January 2015, respectively.[2][3] The older Qinshan Nuclear Power Plant is nearby. In December 2014 it was announced that units 3 and 4 would be of the Hualong-1 (updated CPR-1000) design.[4] ...
We estimate the contamination risks from the atmospheric dispersion of radionuclides released by severe nuclear power plant accidents using the ECHAM/Modular Earth Submodel System (MESSy) atmospheric chemistry (EMAC) atmospheric chemistry-general circulation model at high resolution (50 km). We present an overview of global risks and also a case study of nuclear power plants that are currently under construction, planned and proposed in the Eastern Mediterranean and Middle East, a region prone to earthquakes. We implemented continuous emissions from each location, making the simplifying assumption that all potential accidents release the same amount of radioactivity. We simulated atmospheric transport and decay, focusing on 137Cs and 131I as proxies for particulate and gaseous radionuclides, respectively. We present risk maps for potential surface layer concentrations, deposition and doses to humans from the inhalation exposure of 131I. The estimated risks exhibit seasonal variability, with the highest
Produced by controlled non-explosive nuclear reactions, nuclear power accounts for 6% of the worlds energy and an approximate 13% of the worlds electricity supply (World Nuclear News 2010). Nuclear power has accumulated worldwide regards towards a positive move into the goal of sustainability. Conversely, the use of nuclear power has grown to become a major concern due to its obvious destructive effects on the environment, people and the world as a whole. Nuclear power although providing a positive approach in the production of renewable energy, it also provides the world extreme vulnerability to destruction. This essay will discuss and provide evidence of the threats and negative impacts nuclear power plants pose to the world. Nuclear power production poses major threats from the start of the production process through uranium mining. Uranium mine sites increasingly have supplied serious threats and impacts to people and the environment mainly through chemical run-offs and gases polluting ...
Finland has four nuclear reactors units in two power plants. The first unit started operation in 1977 and in the early 1980s all four units were in use. During the last few years the aging management of the Nuclear Power Plants (NPP) concrete structures has grown an important issue because the existing structures are reaching the end of their licensed operating lifetime (about 40 years). Therefore the nuclear power companies are developing aging management systems to avoid premature degradation of NPP facilities and to be able to extend their operating lifetime. This paper is about the development of a computerized ageing management system for the nuclear power plants concrete structures. The computerized ageing management system is built upon central database and implementation applications. It will assist the personnel of power companies to implement the aging management activities at different phases of the lifetime of a power plant. It will provide systematic methods for planning, ...
What most people have use for though are Dosimeters you can buy a handheld radiation detector pretty cheap that are good addition to a survival kit. There are different kinds that you can use that will detect radiation. There are radiation badges that will tell you when radiation become high. Workers at nuclear power plants use these to inform them of how much radiation they have been exposed to. Now also children in the Fukushima prefecture have each been given a radiation badge so they know if they are exposed to radiation. Some come in the shape of a pen that you can carry in your pocket while other are made more compact so that you can attach them to your keychain. And then you have what is called a personal radiation monitor. These are also called Dosimeters and also normally called Geiger counters. Although not all use the Geiger-Muller Tube for the radiation detection some use a semiconductor instead. These and mostly the older geiger counters seen are pretty big to carry around, so they ...
In 2008, the KiKK study in Germany reported a 1.6-fold increase in solid cancers and a 2.2-fold increase in leukemias among children living within 5 km of all German nuclear power stations. The study has triggered debates as to the cause(s) of these increased cancers. This article reports on the findings of the KiKK study; discusses past and more recent epidemiological studies of leukemias near nuclear installations around the world, and outlines a possible biological mechanism to explain the increased cancers. This suggests that the observed high rates of infant leukemias may be a teratogenic effect from incorporated radionuclides. Doses from environmental emissions from nuclear reactors to embryos and fetuses in pregnant women near nuclear power stations may be larger than suspected. Hematopoietic tissues appear to be considerably more radiosensitive in embryos/fetuses than in newborn babies. Recommendations for advice to local residents and for further research are made.

Good article about the relative danger of nuclear power. Im afraid this accident will essentially kill nuclear power, which was just starting to get on its feet again as a response to global warming/coal/gas fears. This isnt meant to suggest that nuclear power is not at all dangerous, but simply to put the danger in context. Everything is dangerous. Not a single person has died as a result of the accident at 3 mile island. According to the World Health organization chernobyl caused 4,000 deaths, up until now those are the only deaths attributed to nuclear power. That works out to less than 100 deaths world wide per year for the past 50 years weve been using nuclear power, compared to 126 deaths per year just in the us attributed to candles. Its unclear how many people will die as a result of the problems in japan, but even if that turns out very badly the fact is the death toll attributed to nuclear power is infinitesimal when compared to something like tobacco or alcohol. There may be more ...
The U.S. Nuclear Regulatory Commission, citing serious concerns about equipment failures at the San Onofre nuclear power plant, has prohibited Southern California Edison from restarting the plant until the problems are thoroughly understood and fixed.. The plant has been shut down for two months, the longest in San Onofres history, after a tube leak in one of the plants steam generators released a small amount of radioactive steam. Since then, unusual wear has been found on hundreds of tubes that carry radioactive water.. Neither regulators nor Edison have said when they believe the plant will reopen. San Onofre is a major supplier of power for Southern California, producing about 2,200 megawatts of power, or enough electricity to serve 1.4 million households. It is Southern Californias only nuclear power plant.". Abby Sewell reports for the Los Angeles Times March 28, 2012. [2]. SEE ALSO:. "Feds: Calif. Nuke Plant To Remain Shut for Probe" (AP) [3]. ...

Nuclear power plants use the heat generated from nuclear fission in a contained environment to convert water to steam, which powers generators to produce electricity. Although the construction and operation of these facilities are closely monitored and regulated by the Nuclear Regulatory Commission (NRC), accidents are possible. An accident could result in dangerous levels of radiation that could affect the health and safety of the public living near the nuclear power plant.

Documentation is being prepared to provide the USNRC with potential structural safety issues and acceptance criteria for use in continued service evaluations of nuclear power plants. Accomplishments include development of a Structural Materials Information Center containing data and information on the time variation of 144 material properties under the influence of pertinent environmental stressors or aging factors, evaluation of models for potential concrete containment degradation factors, development of a procedure to identify critical structures and degradation factors important to aging management, evaluations of nondestructive evaluation techniques. assessments of European and North American repair practices for concrete, review of parameters affecting corrosion of metals embedded in concrete, and ...
In spite of industries effort over the last 40 years, corrosion-related issues continue to be one of the largest unresolved problems for nuclear power plants worldwide. There are several types of strange corrosion phenomena from the point of view of our current understanding of corrosion science established in other fields. Some of these are IGSCC, PWSCC, AOA, and FAC (Erosion-Corrosion). Through studying and coping with diverse corrosion phenomena, the author believes that they share a common basis with respect to the assumed corrosion mechanism (e.g., local cell action hypothesis). In general, local cell action is rarely severe since it produces a fairly uniform corrosion. The long cell action that transports electrons through structures far beyond the region of local cell corrosion activities has been identified as a basic mechanism in soil corrosion. If this mechanism is assumed in nuclear power plants, the structure becomes anodic in the area where the potential is less positive and ...
Figure 2: Categorization of Radioactive Sources.. What we learn from Fukushima. The Fukushima Daiichi nuclear disaster was a series of equipment failures, nuclear meltdowns, and releases of radioactive materials at the Fukushima I Nuclear Power Plant, following the Tohoku earthquake and tsunami on 11 March 2011. The accident at Fukushima Daiichi nuclear power plant in Japan released about 940 PBq (iodine-131 equivalent) of radioactive material, mostly on days 4 to 6 after the tsunami. In May 2013, United Nation Scientific Commission on the Effects of Atomic Radiation (UNSCEAR) reported that "Radiation exposure following the nuclear accident at Fukushima-Daiichi did not cause any immediate health effects. It is unlikely to be able to attribute any health effects in the future among the general public and the vast majority of workers." The lessons that we should be learned from the accident at Japans Fukushima-Daichii nuclear power plant, are that emergency generators should be better protected ...

Historic news that Japan will phase out nuclear power has rounded off yet another terrible week for the global nuclear industry.. Japans decision to end its reliance on nuclear power by the 2030s means it will join countries such as Germany and Switzerland in turning away from nuclear power after last years Fukushima disaster.. This is an incredible step forward for a country that was once 30 percent dependent on nuclear power and follows a wave of public protests in a country not known for civil disobedience.. The decision comes as two nuclear reactors are out of action in Belgium after indications of cracks were found in their reactor vessels.. And adding to the industrys woes this week, Spain said it will close its Garoña nuclear power plant in July 2013, while Quebecs new government has confirmed it will also close the Gentilly-2 nuclear reactor.. These are momentous times.. Greenpeace has cautiously welcomed Japans new "energy and environment strategy" as a long overdue decision. ...
The Nuclear Power Corporation of India Limited (NPCIL) is an Indian public sector undertaking based in Mumbai, Maharashtra. It is wholly owned by the Government of India and is responsible for the generation of nuclear power for electricity. NPCIL is administered by the Department of Atomic Energy (DAE). NPCIL was created in September 1987 under the Companies Act 1956, "with the objective of undertaking the design, construction, operation and maintenance of the atomic power stations for generation of electricity in pursuance of the schemes and programmes of the Government of India under the provision of the Atomic Energy Act 1962." All nuclear power plants operated by the company are certified for ISO-14001 (Environment Management System). NPCIL was the sole body responsible for constructing and operating Indias commercial nuclear power plants till setting up of BHAVINI Vidyut Nigam) in October 2003. As of 10 August 2012 the company had 21 nuclear reactors in operation at seven locations, a ...
Looking at French studies [4,5], similar to the German one, we see that they indeed could not find any significant relation between cancer incidence and absorbed dose or closeness to a nuclear power plant.. Further reading reveals that they have not been able to process data considering children moving around prior to the cancer notice, nor the importance of lifestyle or whether the time the children spend in their homes is of relevance.. All of this summed up leaves us with a report that in effect states: "We think there might be slightly more cases of child cancer around some nuclear power plants, but we dont really know why. And in order for the nuclear plants to be the actual cause, instead of something else, 60 years of radiobiological science must have completely missed something here".. This notwithstanding the Swedish self-proclaimed enviromental movement beats the big drum and claims that it would be "irresponsable to concider constructing new nuclear power plants before it is clear ...
Vietnam has put off construction work on its first nuclear power plant..

The Great East Japan Earthquake that occurred on March 11, 2011, and subsequently occurring Fukushima Daiichi Nuclear Power Plant accident caused tremendously serious damage and left a long-lasting emotional scar on the Japanese people. In particular, the power plant accident thrust upon us the fundamental question "Who owns the information?" The people were confused at that time since many evacuees were exposed to needless radiation because the government did not disclose information immediately after the accident or since various specialists spoke about the radiation exposure from different positions. Even now, one cannot say that the government or Tokyo Electric Power Company (TEPCO) has fulfilled their accountability to the Japanese people regarding the cause of the accident. Now about four years have passed since the accident. We still have 230 thousand or more evacuees (as of December 2014) and a polluted water problem. However, the accident has started to fade from many peoples memory. ...

At 9:40 am (local time) on Thursday there was an explosion at EDFs Flamanville nuclear power plant in northern France.. This explosion was reportedly well outside of the nuclear zones at the plant, as was the fire that apparently caused it. Authorities are saying that, this being the case, there is no risk of contamination to the public.. The facts as we now know them are that: a fire in the turbine hall caused an explosion; this was in a non-nuclear part of the plant; an on-site team brought the fire under control by 11 am; the cause of the fire is unknown but sabotage has been ruled out apparently; the reactor was taken offline by EDF in response to the explosion and fire; and, while there were no reported injuries, 5 people were apparently treated for fumes and smoke inhalation.. Reuters provides some interesting context:. "Industry experts said fires of this nature happened fairly frequently and that there was unlikely to have been any release of radiation, but Flamanville is at the centre ...

The electrical production of a Nuclear Power Plant depends on the performance of the Circulating Water System, which works removes the residual heat of the plant according to regulations. Owing to the old age of Ascós NPP Cooling Towers, which are a part of the Circulating Water System, the performance of this system has been reduced. Consequently, the electrical production of the facility has been decreased and the number of events, which triggers the turbine to trip, have been augmented. The aim of this project is to study the viability of a set of modi cation and improvement proposals of the Cooling Towers. A survey of the current performance of the towers has been carried out. The results of this previous study shows that: On the one hand, the cooling capability of the Natural Draft Tower has decreased around 4 oC from their construction. This deterioration has been intensi ed at a rate of 1 oC/year during the last three years. On the other hand, the performance of the Mechanical Draft ...

This publication describes the procedures for calculating the margins of nuclear power plants in relation to human induced external hazards. It focuses on plant and systems performance evaluations. A two level approach for margin assessment is provided. The first level consists of a deterministic procedure in which for each scenario the existence of at least one undamaged success path to comply with the fundamental safety function is investigated. This procedure can be subsequently extended to calculate probability measures such as conditional core damage probability and the conditional probability of spent fuel damage. In the most elaborated stage probabilistic safety assessment (PSA) techniques are introduced giving consideration to the probabilistic aspects of the hazards and of the capacity of structures systems and components (fragility). Event tree and fault tree models are used to compute PSA metrics such as core damage frequency large early release frequency and frequency of spent fuel ...
