Available in PDF, EPUB and Kindle. Book excerpt: The US Nuclear Regulatory Commission has sponsored studies to develop a ''LEAKAGE-BEFORE-FAILURE'' model for use in severe accident risk assessments to provide a means of accounting for significant containment leakage prior to reaching the containment threshold pressure. Six containment types have been studied (large dry, subatmospheric, ice condenser, Mark I, II, and III). Potential leak paths through major containment penetration assemblies were investigated and upper-bound estimates of leak areas established. These leak areas may result from increasing internal pressure and degradation of nonmetallic seal materials due to severe accident conditions. This paper describes the approach and summarizes the results and conclusions of this study.

Available in PDF, EPUB and Kindle. Book excerpt: In 1962 tile US Atomic Energy Commission published TID-14844, C̀̀alculation of Distance Factors for Power and Test Reactors̀̀ which specified a release of fission products from the core to the reactor containment for a postulated accident involving s̀̀ubstantial meltdown of the core.̀̀ This s̀̀ource term, ̀̀ tile basis for tile NRCs̀ Regulatory Guides 1.3 and 1.4, has been used to determine compliance with tile NRCs̀ reactor site criteria, 10 CFR Part 100, and to evaluate other important plant performance requirements. During the past 30 years substantial additional information on fission product releases has been developed based on significant severe accident research. This document utilizes this research by providing more realistic estimates of the s̀̀ource term ̀̀release into containment, in terms of timing, nuclide types, quantities and chemical form, given a severe core-melt accident. This revised s̀̀ource term ̀̀is to be applied to the design of future light water reactors (LWRs). Current LWR licensees may voluntarily propose applications based upon it.

Committee on Lessons Learned from the Fukushima Nuclear Accident for Improving Safety and Security of U.S. Nuclear Plants and published by National Academy Press. This book was released on 2014-10-29 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The March 11, 2011, Great East Japan Earthquake and tsunami sparked a humanitarian disaster in northeastern Japan. They were responsible for more than 15,900 deaths and 2,600 missing persons as well as physical infrastructure damages exceeding $200 billion. The earthquake and tsunami also initiated a severe nuclear accident at the Fukushima Daiichi Nuclear Power Station. Three of the six reactors at the plant sustained severe core damage and released hydrogen and radioactive materials. Explosion of the released hydrogen damaged three reactor buildings and impeded onsite emergency response efforts. The accident prompted widespread evacuations of local populations, large economic losses, and the eventual shutdown of all nuclear power plants in Japan. "Lessons Learned from the Fukushima Nuclear Accident for Improving Safety and Security of U.S. Nuclear Plants" is a study of the Fukushima Daiichi accident. This report examines the causes of the crisis, the performance of safety systems at the plant, and the responses of its operators following the earthquake and tsunami. The report then considers the lessons that can be learned and their implications for U.S. safety and storage of spent nuclear fuel and high-level waste, commercial nuclear reactor safety and security regulations, and design improvements. "Lessons Learned" makes recommendations to improve plant systems, resources, and operator training to enable effective ad hoc responses to severe accidents. This report's recommendations to incorporate modern risk concepts into safety regulations and improve the nuclear safety culture will help the industry prepare for events that could challenge the design of plant structures and lead to a loss of critical safety functions. In providing a broad-scope, high-level examination of the accident, "Lessons Learned" is meant to complement earlier evaluations by industry and regulators. This in-depth review will be an essential resource for the nuclear power industry, policy makers, and anyone interested in the state of U.S. preparedness and response in the face of crisis situations.

These containments are designed according to all applicable code requirements for nuclear reactor containment structures.
Book Synopsis Revised Accident Source Terms for Light-water Reactors by :
Download or read book Revised Accident Source Terms for Light-water Reactors written by and published by . This book was released on 1995 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents revised accident source terms for light-water reactors incorporating the severe accident research insights gained in this area over the last 15 years. Current LWR reactor accident source terms used for licensing date from 1962 and are contained in Regulatory Guides 1.3 and 1.4. These specify that 100% of the core inventory of noble gases and 25% of the iodine fission products are assumed to be instantaneously available for release from the containment. The chemical form of the iodine fission products is also assumed to be predominantly elemental iodine. These assumptions have strongly affected present nuclear air cleaning requirements by emphasizing rapid actuation of spray systems and filtration systems optimized to retain elemental iodine. A proposed revision of reactor accident source terms and some im implications for nuclear air cleaning requirements was presented at the 22nd DOE/NRC Nuclear Air Cleaning Conference. A draft report was issued by the NRC for comment in July 1992. Extensive comments were received, with the most significant comments involving (a) release fractions for both volatile and non-volatile species in the early in-vessel release phase, (b) gap release fractions of the noble gases, iodine and cesium, and (c) the timing and duration for the release phases. The final source term report is expected to be issued in late 1994. Although the revised source terms are intended primarily for future plants, current nuclear power plants may request use of revised accident source term insights as well in licensing. This paper emphasizes additional information obtained since the 22nd Conference, including studies on fission product removal mechanisms, results obtained from improved severe accident code calculations and resolution of major comments, and their impact upon the revised accident source terms. Revised accident source terms for both BWRS and PWRS are presented.

Gieseke and published by . This book was released on 1984 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is volume 5, dealing with the surry nuclear power plant, of a seven-volume report of work done at battelle's columbus laboratories to estimate the amount of radioactive material that could be released from light water reactor (lwr) power plants under specific, hypothetical accident conditions. to make these estimates, five power plants were selected that represent the major categories of lwrs: three pressurized water reactors (pwrs) and two boiling water reactors (bwrs). specifications and data from these plants, along with data from laboratory experiments, were input to computer codes designed to describe various conditions prevailing and physical processes occuring inside reactor systems, including the containment and other buildings. ultimately, these computer codes provide an estimate of how much radioactive material would be able to escape to the environment if a specific series of events (an "accident sequence") took place. this volume reports the results of the analysis of the surry power station, a westinghouse pwr housed in a large, dry, high-pressure containment building. the specific accident sequences investigated for the surry plant were selected to represent cases of high risk, severe consequences, and most importantly, a wide range of physical conditions. the computer codes used to analyze the accident sequences include the new code march 2. the surry plant was previously examined in this study using an earlier version of the code, march 1.1; those results were reported in volume 1 of this series. other power plants included in the study are peach bottom bwr (volume 2); grand gulf bwr (volume 3); sequoyah pwr (volume 4); and zion pwr (volume 6). the seventh volume will address technical questions raised during peer review meetings sponsored by the nuclear regulatory commission.
