Title: Shutdown decay heat removal analysis of a General Electric BWR3/Mark I: Case study
Abstract: A General Electric Boiling Water Reactor (BWR3) with a Mark I containment has been evaluated as part of Task Action Plan A-45, ''Decay Heat Removal Requirements.'' Probabilistic risk assessment models were constructed to determine the dominant internal, randomly initiated accident sequences and special emergency sequences (e.g., earthquakes). The dominant sequences were reviewed to determine what modifications might be made to enhance the plant's ability to remove decay heat. Modifications which held promise went through a preliminary cost and design analysis. Additionally, the impact on the probability of core melt accidents was estimated given implementation of modifications. In the final step, these results were combined in a value-impact format according to NRC guidelines.
