The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) held another presentation in its monthly Community of Practice (CoP) series last month. RP3C chair Steven Krahn opened the meeting with brief introductory remarks about the importance of risk-informed, performance based (RIPB) decision-making and the need for new approaches to nuclear design that go beyond conventional and deterministic methods.

The compound system doubling time of the Clinch River Breeder Reactor has been evaluated for a broad range of breeding ratios and fuel cycle parameters. Reprocessing plant fissile inventory and fissile losses due to incomplete fuel recovery are shown to have a strong influence on the doubling time when the breeding ratio is low. If the breeding ratio is above 1.2, fissile losses are much less significant and acceptable doubling times are achieved.
