SUBJECT:
NRC INSPECTION REPORT NO. 50-275/99-03; 50-323/99-03 AND EXERCISE
Dear Mr. Rueger:
This refers to the inspection conducted on January 24 through March 6,1999, at the Diablo
Canyon Nuclear Power Plant, Units 1 and 2, facility. The enclosed report presents the results
of this inspection.
However,
During the 6-week period covered by this inspection period, your conduct of activities at the
Diablo Canyon Nuclear Power Plant facilitywas generally characterized by safety-conscious
operations, sound engineering and maintenance practices, and good radiation protection
support.
However, four violations of NRC requirements varying in level of significance were
identified.
The most significant violation, which occurred in early 1998, involved the failure to perform an
adequate safety evaluation in accordance with 10 CFR 50.59 for an issue that involved an
unreviewed safety question
(EA 98-517).
Specifically, the issue involved eliminating Diablo
Canyon's dependence
on the Morro Bay Power Plant for reliable offsite power. After
consultation with the Director, Office of Enforcement, the NRC is exercising enforcement
discretion in accordance
with VII.B.6 of the Enforcement Policy and refraining from issuing a
Notice of Violation. Discretion is appropriate because of: (1) confusion surrounding the
determination of whether the change constituted an unreviewed safety question, (2) the
similarity to other issues previously cited for which corrective actions have been taken and are
sufficiently broad to address this violation (EA 98-364), and (3) the apparent improvement in
grid reliabilitythat resulted from the change.
The three additional violations of NRC requirements that occurred are being treated as
noncited violations, consistent with Appendix C of the Enforcement Policy. The circumstances
associated
with each of the noncited violations are described in the enclosed inspection report.
If you contest any of these violations or the severity level of the noncited violations, you should
provide a response within 30 days of the date of this inspection report, with the basis for your
denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington
DC 20555-0001, with copies to the Regional Administrator, Region IV, and the Director, Office
of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001.

As we reviewed the aggregate performance during the recently completed Unit 1 refueling
outage described in this report, it was noted that your staff faced a number of challenges such
as the sudden decrease
in reactor coolant system level, the inadvertent loss of spent fuel pool
cooling, and the higher than expected radiological exposure.
Based upon both number and
potential consequences
of these challenges, numerous questions have arisen concerning the
outage control practices at Diablo Canyon.
Therefore, we would like to schedule a meeting with
your management team to discuss your overall performance during Refueling Outage 1R9.
This meeting would seem to be most appropriately conducted following the completion of your
outage self-critique. My staff willcontact your licensing organization to make the appropriate
arrangements.
In accordance with 10 CFR 2.790 of the NRC's "Rules. of Practice," a copy of this letter and
its'nclosure
willbe placed in the NRC Public Document Room (PDR).
Should you have any questions concerning this inspection, we willbe pleased to discuss them
with you.
Sincerely,
en E.
