Therefore, the emergency cooling system for the water cooled delay beds will be removed from service soon after reactor shutdown to permit decommissioning work on this system early in the schedule.3.4.7 All piping connections which penetrate the contain-ment will be severed, capped and welded outside the containment, except for the containment vacuum breaker assembly and associated penetration.

Electrical penetrations will be left as is. The ventilation supply and exhaust ducts will be severed and welded shut outside the containment.

A six inch pressure equalization line equipped with a replaceable absolute filter will be installed on the containment to prevent a pressure differential from developing between the inside and outside of the containment.

In addition, the containment vacuum breaker assembly was left as-is per NCR 95-00043.3.4.8 The outer door of the emergency air lock and the equipment door on Elevation 116' will be welded closed. The inner doors of the personnel air lock on Elevation 116' and the access lock on Elevation 176'-6" will be welded in the open position.

The interlock mechanisms in these two latter locks will be disabled and the outer door on each lock will be secured with a heavy duty padlock.3.4.9 Flammable materials other than electrical cables and solid graphite left in the sealed reactor vessel will be removed from the containment.

AUG 14 2009 Revision 5 Other possible radiological hazards could occur in the event of a fire, flooding, or severe local storm damage. Since all readily flammable material has been removed as appropriate from the SAFSTOR facility, the chance of fire has been reduced considerably.

Flooding has been discussed in Section 4.2.Since this SAFSTOR facility is in the immediate vicinity of Units 2-3, which are operating, any local condition which may require emergency action will be apparent to the Unit 2-3 operating staff so that they can take appropriate, timely action.4.4.7 Processing of Unit 1 Liquid Radwaste Any liquid waste created or found at Unit 1 will be designated as Unit 1 waste and appropriately reported to the NRC in accordance with Technical Specifications.

This waste will be transferred to the PBAPS radwaste facility located between Units 2 and 3 for processing.

This waste will be clearly designated as belonging to the Unit 1 facility.

This process will be controlled by written procedures.
