Gentlemen:
This refers to the inspection performed by Messrs. E. T. Baker, J. B. Jacobson,
P. Prescott, R. Wilson, E. Trottier and R. McIntyre of the Vendor Inspection
Branch on February 2-13 and March 2-6, 1987 at the San Onofre Nuclear Generating
Station, Units 1, 2, and 3. The inspection related to activities authorized
by NRC License Nos. DPR-13, NPF-10, and NPF-15. Our findings were discussed
with Mr. H. E. Morgan and others of your staff at the conclusion of the
inspection.
The purpose of this inspection was to review the implementation of procurement,
vendor interface, and 10 CFR Part 21 programs at San Onofre. Additionally, a
review of specific vendor related technical issues was conducted.
One finding concerning the procurement of a commercial grade circuit breaker
for a safety related application and one finding concerning the potential use
of,unqualified butt splice connectors were identified. The two findings will
be classified as Potential Enforcement Findings (50-206/87-02-01 and 50-361/
87-03-01) and will be referred to the NRC Region V office for their review and
appropriate action.
Should you have any questions on this matter, we would be pleased to discuss
them with you.
Sincerely,
8706150167 870608

POTENTIAL ENFORCEMENT FINDINGS
Southern California Edison Company
Docket Nos. 50-206, 50-361
San Onofre Units 1 and 2
As a result of the inspection conducted on February 2-13 and March 2-6, 1987,
and in accordance with the "General Statement of Policy and Procedures for
NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986), the following
Potential Enforcement Findings were identified.
A. Potential Enforcement Finding 50-206/87-02-01
Criterion III, Appendix B to 10 CFR Part 50 states in part, "Measures
shall be established to assure that applicable regulatory requirements
and the design basis, as defined in §50.2 and as specified in the
license application, for those structures, systems, and components, to
which this appendix applies are correctly translated into specifications,
drawings, procedures, and instructions."
Criterion V, Appendix B to 10 CFR Part 50 states in part, "Activities
affecting quality shall be prescribed by documented instructions,
procedures, or drawings, of a type appropriate to the circumstances
and shall be accomplished in accordance with these instructions,
procedures, or drawings."
Contrary to the above, SONGS Unit No. 1 Equipment Qualification (EQ)
Document Package No. M38777 allows the use of AMP PIDG butt splice
connector terminals in any Class 1E system in any plant location. These
connectors, Model No. 53549-1, are not similar in construction to those
tested, although the environmental qualification is based upon similarity.
Additionally, for the connectors which were tested no performance criteria
were established and-failures which occurred during testing were not
properly justified.
B. Potential Enforcement Finding 50-361/87-03-01
10 CFR Appendix B, Criterion XVI, states, in part, "Measures shall be
established to assure that applicable regulatory requirements and the
design basis.. .for those structures, systems, and components to which
this appendix applies are correctly translated into specifications,
drawings, procedures and instructions.. .Measures shall also be established
for the selection and review for suitability of materials, parts,
equipment and processes that are essential to the safety-related
functions of structures, systems and components."
Southern California Edison's material control procedure S0123-XI-2.1,
paragraph 6.4, "Level III-Verification Method," states that this level
of procurement is applicable to quality affecting items whose critical
characteristics are capable of 6eing verified after receipt by inspection
and/or testing.
Contrary to the above, on Maintenance Order 8504117800 SCE installed in a
safety-related function and operated SONGS Unit 2 for 20 days with a
circuit breaker which had been purchased as commercial grade and was
inadequately evaluated for its ability to function during a seismic event.
At the end of the 20 day period, SCE replaced the breaker with one
received from Brown Boveri with documentation that it was qualified in
accordance with IEEE-344. The breaker's function is to control activation
of one train of main steam isolation and one train of auxiliary feedwater.
SCE's operability determination wa$ based on an external examination of
the replacement breaker. This examination provided no assurance that
the configuration of the operating mechanism of the replacement breaker
was sufficiently identical to the breaker which was originally qualified
by testing and does not justify the conclusion that the replacement
breaker would function properly during a seismic event.
