The in-service inspection program of reactor pressure vessels is mainly based on the ultra-sinic method, visual checking of inner and outer surfaces as well as pressure and leak tests. The test procedure require a design of the pressure vessel suitable for the test methode and the possibility to remove the pressure vessel internals. the possibility to remove the pressure vessel internals. For the outside inspection a gap of sufficient width is mandatory. The present status of the ulta-sonic method and of the inner and outer manipulators affords to conduct the in-service inspection program in form of automatic checkings. The in-service inspection program for NCS-80, the Nuclear Container-Sehip design of 80,000 shp, is intergrated in the refueling periods due to the request for a high availability of the ship and reactor plant.
