Equipment qualification for the Sizewell 'B' pressurized water reactor

A programme of Equipment Qualification in support of the Sizewell 'B' Pressurized Water Reactor is being undertaken within the UK. The multi-disciplinary teams of NNC's R and D Division are responsible for both Equipment Qualification testing and investigations of the underlying methodology. A brief overview of Equipment Qualification is presented together with a more detailed discussion of qualification for ''harsh environment'' operation, and a description of some of the supporting development undertaken by NNC.
