[en] The Management Advisory Committee of the Inspection Validation Centre (MAC/IVC) was set up by the Chairman of the UKAEA early in 1983. IVC has been established for the purpose of validating the techniques, equipment and personnel proposed by the CEGB for use in the ultrasonic inspection at different stages of the fabrication, erection and operation of the CEGB's proposed PWR reactor pressure vessels and such other components as are identified by the CEGB. This first report sets out the scope and policy of the Committee and the technical progress made. A list of ultrasonic inspections agreed to be validated is given. (U.K.)
