3/4.6.l.4 INTERNAL PRESSURE The limitations on containment internal pressure ensure that:
- 1) the containment structure is prevented from exceeding its design negative pressure differential with respect to the outside atmosphere of 3.5 psig, and 2) the containment peak pressure does not exceed the design pressure of 47 psig during the limiting pipe break conditions.
The pipe breaks considered are LOCA and steam line breaks.
The limit of 0.3 psig for initial positive containment pressure is consistent with the accident analyses initial conditions.
The maximum peak pressure expected to be obtained from a LOCA or steam line break event is ~ 47 psig.
