Structural research needs for Clinch River Breeder Reactor licensing

Abstract

This paper discusses several structural issues for the Clinch River Breeder Reactor Plant (CRBRP) that need to be investigated before the review for an operating license begins. The issues exist because of differences between the CRBRP structures and typical light water reactor (LWR) plant structures. CRBRP structures are generally larger and must withstand loads characterized by lower pressures and higher temperatures than occur in LWRs. In the paper each major issue is described along with research needed to determine its impact on plant safety.
