Subject:
NRC Inspection of Diablo Canyon Units
and
This refers to the routine inspection conducted by H.
Wong and M. Miller during the period of February 4 through March 16, 1992.
This inspection examined your activities as authorized by NRC.License Nos.
At the conclusion of the inspection, discussions of their findings were held with you and other members of your staff.
Areas examined during this inspection are described in the enclosed inspection report.
Within these areas, the inspection consisted of selective examinations of procedures and representative records, interviews with personnel, and observations by the inspectors.
No violations or deviations were found within the scope of this inspection.
However, apparent weaknesses were identified in the maintenance performed on
'some of the backdraft dampers of the containment fan coolers unit in Unit 1 and in the actions taken to correct the deficiencies.
These weaknesses could have led to the inoperability of three containment fan cooler units during certain design bases accidents.
This matter, which was discussed at the management meeting held on April 2, 1992, is still being reviewed and will be addressed in a future inspection report.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice,"
a copy of this letter and the enclosure will be placed in the NRC Public Document Room.
Should you have any questions concerning this inspection, we will be pleased to discuss them with you.
Sincerely, Ihc S.
