Results of USNRC (Nuclear Regulatory Commission) Research on Fuel Rod Behavior During LOCAs (Loss of Coolant Accidents)

摘要

The understanding of fuel rod behavior during large break loss of coolant accidents (LOCAs) is much more complete now than in January 1974 when licensing criteria were promulgated in 10 Code of Federal Register (CFR) Part 50. This paper presents the results of research sponsored by the United States Nuclear Regulatory Commission that has contributed to this improved understanding of fuel rod behavior. Since the USNRC believes that safety is best served when decisions are based on realistic calculations, the paper also summarizes the possible impact of research results on licensing criteria.
