. of NUREG 0737 Item II.K.3.25 "Effect of Loss of A.C. Power on Pump Seals"

Dear Sir:

Reference (a) submitted the generic BWR Owners ~ Group position on NUREG 0737 Item II.K.3.25 "Effect of Loss of Alternating Current Power on Pump Seals". Boston Edison Company (BECo) endorsed this position in our Reference (b) response and stated that no modifications related to this item were planned for Pilgrim Nuclear Power Station (PNPS).

I

Supplemental information to the BWR Owners Group evaluation.of NUREG 0737 Item II.K.3.25 was transmitted to the NRC in Reference (c). Boston Edison Company has reviewed this supplemental informhtion and has determined that the test results from Byron Jackson apply to PNPS, based on the similarity of pumps, to those at PHPS. Two tests were conducted on Byron Jackson pumps and both showed that seal leakage is acceptable even with the loss of seal cooling.
