_Gentlement I

Your letter dated November 21, 1973, responded to our letters dated

~

i:

July 3 and August 7,1973; in part, regarding protection of equipment important to safety against flooding due to rupture of non-Category I l

equipment or piping in the Oyster Creek facility. Following are items i

of concern regarding your response:

4 1.

You stated that the condenser room, which contains feedwater and condensate pumps and 460V MCCs, is closed off from the adjacent

)

(main condenser) rooms by four double doors that are normally in the closed position. Figure I-4-9, " General Arrangement, Turbine Building - Basement Floor Plan", shows these doors, two i

parallel sets of two doors in series, open outward relative to the main condenser room. Based on the flooding rate of the main '

condenser room,1 foot per minute as stated in your response, the doors would be subjected to a relatively high head of water within a short period of' time. Explain how the doors are designed to i

remain closed and watertight against the expected head of water L'

that would occur if the condenser circulating water pumps were to continue operating for a period of up to 15 minutes after i

rupture of the condenser circulating water pipe expansion joint.

Describe the damage that could occur to equipment important to L

safety and the consequences relating to safe shutdown of the facility if the pumps should continue op' rating and if the doors e

are forced open. Explain how procedures would. mitigate the con-sequences of such an occurrence.

2.

Explain how equipment important to safety in the condensate pump room is protectes from rupture of the condensate transfer piping d

to the condensate storage tanks.

Piping exists near the ceiling in the room containing the 4160 kV

. switchgear. - Is this piping designed as Category I? If the pipe is non-Category I design, explain the consequences of its rupture regarding safe shutdown of the facility.
