Dear ifr. Carey:

SUBJECT:
TMI Action Item II.K.3.25, Integrity of RCP Seals Re:
Letter, J. Carey to S. Varga, December 30, 1981 He have reviewed your response to TMI Action Item II.K.3.25.
This Action Item requires you to demonstrate that the integrity of your reactor coolant pump (RCP) seals is maintained (e.g., adequately cooled) during a loss-of-offsite-power event.
Your response stated that the reactor coolant pump seals are cooled by two independent methods:
(1) The chemical and volume control system, and (2) The component cooling water system. During a loss of offsite power event, the RCP motor is de-energized and both cooling systems to the seals are terminated. However, the diesel generators are automatically initiated and the seal injection flow and the component cooling water to the themal barrier heat exchanger are automatically restored within seconds.
Either of these cooling supplies is adequate to provide seal cooling and prevent seal failure during a loss of offsite power event.
i We find your submittal acceptable to c16secutt Action Plan Item II.K.3.25 i
for Beaver Valley Unit 1.
Sincerely, priginal signed by:
