Sizewell ‘B’ - a one tenth scale containment model test for the UK PWR programme

Abstract

To fulfil a commitment given to H.M. Nuclear Installations Inspectorate, the CEGB has carried out a pressure test on a one tenth scale prestressed concrete model of the Sizewell ‘B’ containment building in order to validate the computer codes used in the design of the full size structure. This paper describes the model used, its differences and similarities to the full size structure, the construction of the model, the instrumentation used and outlines the test predictions as compared to such test results as were available immediately after completion of testing.
