Attention:
Mr. Harold B. Ray, Senior Vice President, Nuclear
Gentlemen:
This refers to the routine inspection conducted by Messrs. C. W. Caldwell,
D. L. Solorio and C. D. Townsend of this office on June 4, 1992 through
July 16, 1992, of activities authorized by NRC License Nos. DPR-13, NPF-10 and
NPF-15, and to the discussion of our findings held by the inspectors with
Mr. H. E. Morgan and other members of the Southern California Edison staff at
the conclusion of the inspection.
Areas examined during the inspection are identified 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 inspector.
Based on the results of this inspection, one of your activities appeared to be
in violation of NRC requirements, as specified in the enclosed Notice of
Violation (Notice). This violation is an example of weakness in the interface
between Station Technical (STEC) and Operations in controlling plant equipment
configuration during performance of surveillance activities. Specifically,
Station Technical personnel did not obtain approval from the Senior Reactor
Operator (SRO) Operations Superintendent to perform an inservice test of a
Unit 2 auxiliary feedwater pump. As a result, the SRO was not involved to the
level required by both Operations and Engineering procedures.
A second instance of this weakness in the STEC/Operations interface was noted
in which a Unit 2 salt water cooling (SWC) pump became inoperable due to a
misaligned valve as detailed in licensee event report 2-92-009. In that case,
Operations personnel failed to recognize that an Engineering procedure did not
comply with station requirements to provide for an Operations sign-off and an
independent verification of equipment manipulation. Thus, proper
configuration control was not maintained.
You are required to respond to this letter and should follow the instructions
specified in the enclosed Notice when preparing your response. In your
response, you should document the specific action taken and any additional
actions you plan to prevent recurrence. Also, please include your evaluation
of the adequacy of the interface between Station Technical and Operations to
.ensure
proper configuration control of equipment. After-reviewing your
response to this Notice, including your proposed corrective actions and the
9208310298 920813
ADOCK 05000206
G
results of future inspections, the NRC will determine whether further NRC
enforcement action is necessary to ensure compliance with NRC regulatory
requirements.
In accordance with 10 CFR 2.790, of the NRC's "Rules of Practice," a copy of
this letter, the enclosures, and your response will be placed in the NRC
Public Document Room.
The response directed by this letter and the accompanying Notice are not
subject to the clearance procedures of the Office of Management and Budget as
required by the Paperwork Reduction Act of 1980, PL 96-511.
Should you have any questions concerning this inspection, we will be pleased
to discuss them with you.
Sincerely,
S. A. Richards, Chief
Reactor Projects Branch
