Available in PDF, EPUB and Kindle. Book excerpt: The ANSI/ANS-5.1 [1] standard on decay heat in light water reactors is one of the most widely used standards for reactor design and safety analysis. The standard was last revised and issued in 2005. The 2005 revision included several important accomplishments, including incorporation of ENDF/B-VI nuclear data in the development of correction factors implemented in the standard, and revisions to the 'simplified method.' The status of the 2005 ANS-5.1 standard has been summarized previously [2]. Future revisions of the standard under consideration, as proposed by the working group, were to (a) improve the neutron capture effect specification, (b) include contributions from actinides not already addressed by the standard, and (c) specify values for the total recoverable decay energy Q for major fissionable elements. These items are carried over from recommendations by Dickens et al. [3] during development of the 1994 revision. The current working group has also identified the representation of decay heat uncertainties as an area for improvement. This paper discusses recent development activities to further improve and extend the utility of the ANS-5.1 decay heat standard. These developments are in progress, and this paper summarizes the status of the activities. The proposed revisions discussed in this paper are being considered by the working group for adoption in the next publication of the standard.

Available in PDF, EPUB and Kindle. Book excerpt: ANS 5.1-2014 (R2019) sets forth values for the decay heat power from fission products and actinides following shutdown of light water reactors (LWRs) using nuclear fuel initially containing 235U and 238U. The decay heat pwer from fission products is presented in tables and equivalent analytical representations. Contributions from the decay of 239U and 239Np and the contributions from all other actinides are represented separately. Methods are described that account for the reactor operating history, for the effect of neutron capture in fission products, and for assessing the uncertainty in the resultant decay heat power. The standard applies to decay times of up to 1010 after shutdown. This standard provides bases for determining the decay heat power and its uncertainty following shutdown of LWRs. The information in this standard can be used in the design, performance evaluation, and assessment of the safety of LWRs. The methods prescribed in this standard enable the calculation of fission product decay heat power with accuracies comparable to those of summation codes but without the need for complex calculations. The fission product decay heat power values in this standard have the advantage of being developed directly from experimental measurements for time periods

Available in PDF, EPUB and Kindle. Book excerpt: The Savannah River Laboratory (SRL) is upgrading the methods used to predict the post shutdown decay heat of the Savannah River reactors by implementing procedures based on the ANS Decay Heat Power in Light Water Reactors standard. This approach takes advantage of the large volume of research used in developing the standard and establishes compatibility with the nuclear industry. To qualify the decay heat standard for use, a series of comparisons were made between detailed decay heat calculations performed using the SHIELD code system and results obtained from the standard.

Available in PDF, EPUB and Kindle. Book excerpt: This standard presents the requirements of the Nuclear Safety Related Cooling Water Systems (NSRCWS) for Light Water Reactors (LWRs). It establishes nuclear safety requirements in the areas of design, materials, fabrication, placement and testing of systems. This standard is applicable to open and closed NSRCW systems. 58.9-1981 (R2020) provides criteria for the designer which interpret the requirements of Title 10, Code of Federal Regulations, Part 50, "Licensing of Production and Utilization Facilities," Appendix A, "General Design Criteria for Nuclear Power Plants," with respect to design against single failures in safety-related Light Water Reactor (LWR) fluid systems. Means of treating both active and passive failures are addressed for safety-related fluid systems following various initiating events. Current acceptable practice is used as a basis for these criteria.
