50-275 and 50-323 3 JUN 1987 Nr. J.
D. Shiffer, Vice President Nuclear Power Generation c/o Nuclear Power Generation, Licensing Pacific Gas and Electric Company 77 Beale Street, Room 1451 San Francisco, California 94106
Dear Nr. Shiffer:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION - DIABLO CANYON SPENT FUEL POOL RERACKING (TAC NO. 64470 AND 64471)
We have recently learned that some anomalies have been found in the Boraflex neutron absorbing material used in the spent fuel pools at the Point Beach Nuclear Plant and the Quad Cities Station.
See the enclosed letter and report from Commonwealth Edison dated Nay 5, 1987 (Enclosure
( 1)).
Since Boraflex is planned to be used in the proposed modified racks at Diablo Canyon, we request that you provide the additional information identified in Enclosure (2) as soon as possible.
The reporting and/or recordkeeping requirements of this letter affect fewer than ten respondents; therefore, ONB clearance is not required under PL 96-511.
Sincerely, Original signed by
