The containment cooling system and the containment spray system.are redundant to each other in providing post accident cooling of the containment atmosphere.

As a result of this redundancy in cooling capability, the allowable out of service time requirements for the containment cooling system have been appropriately adjusted.

However, the allowable out of service time requirements for the containment spray system have been maintained consistent with that
