" Containment system integt by as defined in Specification TS.1 shall not be violated except when one of the following conditions exist: (a) the reactor is in the cold shut-down condition with the reactor vessel head installed, (b) the reactor is in the refueling shutdown condition with the vessel head removed, or (c) the fuel inside containment has not been used for power operation."
Technical Specification 1.C states in part that: " Containment system integrity exists when the containment vessel, shield building, and ABSVZ are closed and the following conditions are satisfied... 9.
At least one door in each ABSVZ air lock type passage is closed...."
Technical Specification 3.6.A.8 allows the Auxiliary Building Special Vent Zone (ABSVZ) to be opened, "provided such openings are under dir-ect administrative control and can be reduced to less than 10 square feet within 6 uinutes following an accident."
