Available in PDF, EPUB and Kindle. Book excerpt: The construction of pressurized water reactors with large excess reactivities has made possible accidents with fast power excursions. A knowledge of the fastest power transient that a pressurized water reactor is capable of withstanding without destnactive effects is an important factor in its safety aspects. Possible methods of attack are defined for three categories of problems: (1) what constitutes a destructive effect in a pressurized water reactor? (2) by what mechanisms is the heat which is generated within a fuel plate during a transient transferred to the coolant? (3) what mechanisms are available for spontaneous reactivity reduction during a transient? (W.D.M.).

Book excerpt: This paper summarizes a study of light water reactor event sequences which have been investigated for their potential to result in reactivity accidents with severe consequences. The study is an outgrowth of the concern which arose after the accident at Chernobyl and was recommended by the report of the US Nuclear Regulatory Commission (NRC) on the implications of that accident (NUREG-1251). The work was done for the NRC to reconfirm or bring into question previous judgments on reactivity events which must be analyzed for licensing. Event sequences were defined and then a probabilistic assessment was completed to estimate the frequency of the reactivity event and/or a deterministic calculation was completed to estimate the consequences to the fuel. Using the results of this analysis, analysis done by others, and a set of screening criteria developed within this study, judgments were made for each sequence as to its importance, and recommendations were made as to whether the NRC ought to be considering the important sequences as part of the design basis or for further, more detailed, investigation. 31 refs., 9 figs., 1 tab.

This book was released on 1980 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detail study of a Loss of Coolant Accident (LOCA) in a Pressurized Water Reactor was conducted in order to estimate the consequences of the accident using the computer simulation code EMERALD. An effort was undertaken to modify the EMERALD code and to make it operable on the OSU CYBER computer because this program was too large to run on the present OSU system. This modification was done by breaking EMERALD up into two separate codes, which were called IODINE and NOBLGS, each of which was then small enough to run on the OSU computer. The combination of output results generated by IODINE and NOBLGS gives the same results as EMERALD. For this analysis, two release models, differing in the amount of radioactivity which would be released following a LOCA, were considered. Calculations were performed using the IODINE and NOBLGS programs for both of the release models. In these calculations, three major factors were varied to verify the effect of each on the LOCA. They were the primary containment leak rate, spray removal rate, and the atmospheric dilution factors. A set of calculations was carried out to show the effect of the primary containment leak rate in case of an accident. A significant reduction in off-site doses would result in the situation where the containment does not fail. For example, the total whole body and total thyroid doses, at the plant exclusion boundary, are reduced by a factor of about 290 and 190, respectively, in the case where the primary containment remains intact (normal leak rate) compared to the situation where the containment fails, assuming every other factor is unchanged. Studies were also undertaken to illustrate the dependence of the thyroid exposure on the spray removal rate. Higher doses would result, following a LOCA, for the situation with no spray system operating. For instance, an increase in thyroid dose by a factor of about 16.5 was obtained for the case with no spray as compared to the case when the spray operates at full capacity, assuming the containment remains intact for all periods after the accident. Furthermore, the dependency of the meteorological conditions on the off-site exposures due to a LOCA was studied. As expected, the more unfavorable meteorological conditions give higher dose rates. For example, the total thyroid and total whole body doses for all periods at the plant exclusion boundary increase by a factor of about 360 and 730, respectively, when the most unfavorable meteorological conditions, rather than the actual on-site atmospheric conditions, were used.

This book was released on 2013-11-11 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last 30 years, reactor safety technology has evolved not so much from a need to recover from accidents or incidents, but primarily from many groups in the nuclear community asking hypo thetical, searching (what if) ~uestions. This ~uestioning has indeed paid off in establishing preventive measures for many types of events and potential accidents. Conditions, such as reactivity excursions, large break, loss of coolant, core melt, and contain ment integrity loss, to name a few, were all at one time topics of protracted discussions on hypothesized events. Historically, many of these have become multiyear, large-scale research programs aimed at resolving the "what ifs. " For the topic of anticipated and abnormal plant transients, how ever, the searching ~uestions and the research were not so prolific until the mid-1970s. At that time, probabilistic risk methodolo gies began to tell us we should change our emphasis in reactor safety research and development and focus more on small pipe breaks and plant transients. Three Mile Island punctuated that message in 1979. The plant transient topic area is a multidisciplinary subject involving not only the nuclear, fluid flow, and heat transfer technologies, but also the synergistics of these with the reactor control systems, the safety s;,"stems, operator actions, maintenance and even management and the economic considerations of a given plant.

Available in PDF, EPUB and Kindle. Book excerpt: For more than 40 years, IPSN then IRSN has conducted research and development on nuclear safety, specifically concerning pressurized water reactors, which are the reactor type used in France. This publication reports on the progress of this research and development in each area of study - loss-of-coolant accidents, core melt accidents, fires and external hazards, component aging, etc. -, the remaining uncertainties and, in some cases, new measures that should be developed to consolidate the safety of today's reactors and also those of tomorrow. A chapter of this report is also devoted to research into human and organizational factors, and the human and social sciences more generally. All of the work is reviewed in the light of the safety issues raised by feedback from major accidents such as Chernobyl and Fukushima Daiichi, as well as the issues raised by assessments conducted, for example, as part of the ten-year reviews of safety at French nuclear reactors. Finally, through the subjects it discusses, this report illustrates the many partnerships and exchanges forged by IRSN with public, industrial and academic bodies both within Europe and internationally. This publication reflects IRSN's desire to keep an enduring record of its results and to share its knowledge.
