Design, choice of material, execution and quality assurance regarding pressure vessels and pipelines in nuclear power plants

As compared to conventional installations, nuclear plants must satisfy particularly high safety demands, which is reflected in the design, choice of material used, execution and quality assurance for the components of such installations. The paper briefly discusses the current 'safety philosophy' and the catalogue of technical rules and goes on to describe in detail design aspects, the choice of suitable materials and their spheres of use as well as particular factors related to their production. Furthermore the comprehensive test program is presented. (orig.)
