The Sizewell 'B' project and its graded approach to implementing quality assurance

The project scope and the organizational arrangements for its execution are defined. An outline of the structure of the Quality Assurance documentation used within the Project Group and at the Group's interface with its contractors are also included. The Project Group's graded approach to Quality Assurance is discussed with details of the four levels of Quality Assurance controls applied. The application of the levels is then discussed by reference to International Quality System standards and the degree of supervision of suppliers imposed by the Project Group, both in terms of QA-related activities and engineering approval of design and other documentation produced by suppliers. The logic of the approach is also followed through into the production and retention of records required to demonstrate compliance to the PPG, and, via the PPG, to the Regulatory bodies. (author)
