CONTAINMENT SYSTEMS AND THEIR SAFETY FUNCTIONS

GENERAL

1.11. The containment systems should be designed to ensure or contribute to the achievement of the following safety functions:

(a) Confinement of radioactive substances in operational states and in accident conditions,

(b) Protection of the plant against external natural and human induced

events,

(c) Radiation shielding in operational states and in accident conditions.

1.12. The safety functions of the containment systems should be clearly identified for operational states and accident conditions, and should be used as a basis for the design of the systems and the verification of their performance.
