ASME Section XI Task Group on Reactor Vessel Integrity Requirements

Full Description

The purpose of the ASME Section XI Task Group on Reactor Vessel Integrity Requirements was to examine the ASME Code requirements for reactor vessel integrity. As a part of this effort, the historical basis of the current ASME Section III, Appendix G limits for plant operating criteria was revisited. With the benefit of advancing technology, the appropriateness of the existing Code requirements was reexamined.

The goals of the Task Group were to:Review current regulations for material reference toughness, assumed reference flaw size and plant operating criteria, and identify areas of conservatism and potential nonconservatism.Provide recommendations for determining plant operating pressure-temperature limits while maintaining the necessary requirements to assure vessel integrity.
