BREAK PRECLUSION CONCEPT AND ITS APPLICATION TO THE EPRTM REACTOR

摘要

This paper provides a synthesis of the technical basis supporting the Break Preclusion concept and its implementation on the Main Coolant Lines and Main Steam Lines of the EPR™ reactor. In a first step, it describes the background of the Break Preclusion concept, and then it details the requirements associated to its implementation in a Defense In Depth approach. In second steps, main benefits and few illustrative examples are given for the MCL.
