Evaluation of the Core Damage Frequency of the Marine Reactor X

摘要

The Japan Atomic Energy Research Institute has designed a new type marine reactor MRX. The reactor is an integrated type PWR and has passive type safety systems, which require few valve operations for the start of their function. The core damage frequency has been evaluated for the MRX. Analysis result shows the MRX has the low core damage frquency, althouth there is no external power source.
