APPLICANTS' REVISED ANSWER TO NEW ENGLAND COALITION ON NUCLEAR

' POLLUTION'S FIRST SET OF INTERROGATORIES AND REQUEST FOR THE PRODUCTION OF DOCUMENTS TO APPLICANTS

15) For areas outside of containment, what is Applicants' basis for assuming that the areas will be pumped?- What systems will be available to pump the water? Where will the water be pumped to?

Submergence qualification for the cables outside containment identified in Impell Letter No. 0570-32-NY-156 is 30 days. Sufficient margin is included in the qualification evaluation to ensure that these areas will be pumped prior to exceeding the qualification limitation.

This concern was specifically addressed in SBN-1024 8611110097 861103 PDR ADOCK 05000443 G PDR 1 503

k providing the technical justification for the limited submergence qualification.

The two areas requiring submergence qualification for cables are the Main Steam & Feedwater Pipe Chase &

Mechanical Penetration Area. Two sump pumps located in the chase sump will be used to pump the water from this area.

If these pumps are unavailable or cannot be refurbished these areas will be pumped manually by the use of portable sump pumps. Floor drains are provided in the mechanical penetration area which drain to the equipment vault sump containing two sump pumps. If the floor drains become plugged and cannot be unplugged this area will be pumped manually.

The water from the Main Steam and Feedwater Pipe Chase sump is pumped to'the storm drainage system. The water from the Mechanical Penetration Area is pumped from the Equipment Vault Sump to the Floor Drain Tanks in the Waste Processing Building to be processed.
