SUBJECT: NRC INSPECTION REPORT 50-275I98-007; 50-323/98-007 AND NOTICE OF
VIOLATION
Dear Mr. Rueger:
From February 15 through March 28, 1998, a routine NRC inspection was conducted at your
Diablo Canyon Nuclear Power Plant, Units 1 and 2 reactor facilities. The enclosed report
presents the scope and results of that inspection.
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.
Based on the results of this inspection, violations of NRC requirements were identified. The first
violation involved failure to provide a procedure that assured proper stowage of a nonseismic
hoist. This violation was discovered while Unit 2 was conducting midloop operations, and the
hoist was over the operating residual heat removal pump. The second violation involved a
failure to implement refueling procedures
in that the source range monitor high flux alarm was
not restored when the required number of fuel assemblies were placed in the core. The third
violation involved multiple failures to properly implement the clearance procedure.
Clearance
errors have been a previous concern.
The fourth violation involved a failure to translate the
design of the reactor vessel refueling level indicating system into procedures
in that the
shutdown abnormal operating procedures allowed, for several years, the system to be
pressurized to 400 psig when the design pressure of the system was 50 psig. The initial
corrective actions did not address the procedure change process deficiencies that allowed this
'rror
to occur.
These violations are cited in the enclosed Notice of Violation (Notice) and the circumstances
surrounding the violations are described in detail in the enclosed report.
Please note that you
are required to respond to this letter and should followthe instructions specified in the enclosed
9804280093

Notice when preparing your response.
The NRC will use your response,
in part, to determine
whether further enforcement action is necessary
to ensure compliance with regulatory
requirements.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter, its
enclosures,
and your response 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,
Reactor Projects Branch E
