Operational Aspects Of Sizewell B Hiigh Integrity Piping

This paper describes operational features considered during the design of Sizewell B (SXB) nuclear power plant's high integrity nuclear piping, and how well they have performed subsequently in service. It concludes that whilst most of the features have performed well, there is scope for improvement, for example in further reductions in snubbers and whip restraints-which hinder access for in-service inspection.
