Reinforced and prestressed concrete containment for nuclear power plants
Sicherheitsbehälter aus Stahlbeton und Spannbeton für Kernkraftwerke
Overview
This document applies to nuclear power plants with containment vessels (inner containment) made of reinforced or prestressed concrete and fitted with a steel liner. The containment vessel constitutes the structural part of the reactor containment system. The containment vessel, including all penetrations and cooling devices, insofar as their function needs to be taken into account to enable the consequences of accidents to be controlled, shall be designed to withstand the structural, dynamic and thermal loads (such as forces, internal and external excess pressures and temperatures) without exceeding the leakage rate on which the design is based. This document also applies to structural elements that affect the structural stability of the containment vessel. The committee responsible for this standard is NA 062-07-43 AA "Bauteile aus Stahl- und Spannbeton in kerntechnischen Anlagen" ("Components made of reinforced and pre-stressed concrete in nuclear plants") at DIN.
