The containment vessel constitutes the structural part

14、 of the reactor containment system. This standard deals with the design of containment vessels, including all penetrations insofar as their function needs to be taken into account to enable the consequences of accidents to be controlled. Containment vessels need to be able to withstand the structura

15、l, dynamic and thermal loads (such as forces, internal and external excess pressures and temperatures) without exceeding the leakage rate on which their design is based. This document also applies to structural elements that affect the structural stability of the containment vessel. 2 Normative refe
