Rancho Seco Nuclear Generating Station

Heralo, California 95638-9799
Dear Mr. Firlit:
SUBJECT:
PROCUREMENT AND MATERIALS CONTROL INSPECTION (50-312/88-02)
\\
This letter transmits the report of the inspection conducted January 4 through
14, February 10 through 12, and March 7 through 9,1988, at the Rancho Seco
1
Nuclear Generating Station by Messrs. R. P. McIntyre and J. B. Jacobson of the
Vendor Inspection Branch and Mr. W. J. Wagner of Region V.
The inspection was
'
related to activities authorized by NRC License Number DPR-54.
At the conlusion
of the inspection, the findings were discussed with Mr. Gary J. Legner and other
members of your staff.
l
The purpose of the inspection was to review the implementation of your program
for procuring items for safety-related applications and your material control
j
program, both past and present. The results of the inspection identified
i
weaknesses in the procurement program; specifically, the coninercial grade item
dedication process ano the auditing and placement of vendors on the approved
suppliers list (ASL).
The inspection findings identified include: (1) failure
to properly dedicate and provide documentation for several comercial grace
items used in safety-related applications (these items were accepted on the
basis of a "like-for-like" comparison of part numbers without the licensee
adequately) evaluating their suitability for use in these safety-related applica-
<
l
tions); (2 failure to impose the requirements of 10 CFR Part 21 on vendors
where certifications to nuclear specifications were required; and (3) failure
to adequately evaluate vendor quality assurance (QA) programs before placing
the vendors on the approved supplier list (ASL).
Also, certificates of
conformance (C of Cs) for comercial grade procurements from vendors not on
the ASL, were accepted without verification of the validity of the C of Cs.
Certain findings discussed in the report have been ciassified as potential
enforcement findings (50-312/88-02-01. -02 and -03 encloseo) and will be
referred to the NRC Region V office for appropriate action,

POTENTIAL ENFORCEMENT FINDINGS
Sacramento Municipal Utility District
Docket No.: 50-312
Rancho Seco Nuclear Generating Station
License No.: DPR-54
.
As a result of the inspections conducted from January 4 through 14,' February 10
through 12, ano March 7 through 9,1988, and in accordance with the "General
Statement of Policy and Procedures for NLC Enforcement Actions " 10 CFR Part 2. Appendix C (1986), the following potential enforcement findings were
identified:
A.
Potential Enforcement Finding 50-312/88 02 01
i
l
l
The NRC inspectors found that several purchases of spare and replacement
l
comercial grade items to be used in safety-related applications were
accepted on the basis of a "like-for-like" compariscn of part numoer
l
l
without adequate evaluation of their suitability for use in safety-related
l
applications.
Specifically:
1.
A COMSIP catalyst assembly for the hydrogen monitor was purchased
without qualification documentation for use in an environmentally
qualified (EQ) application. Also, no certificate of Confontance
(C of C) for this item was received.
2.
An Agastat relay installed in the undervoltage protection sys.em was
received without any seismic qualification or verification that no
design cr manufacturing changes had been made.
3.
A K3 connercial grace relay was received without any seismic qualifi-
cation or verification that no design or n.anufacturing changes had
been made.
4.
A circuit breaker for use in the "A" inverter vital bus was
functionally tested upon receipt without acceptance criteria being
established (i.e., the trip times were unkncwn.) Also, no verification
of cesign or manufacturing changes was performed.
l
S.
A General Electric (GE) relay in the reactor sampling system was
I
accepted without seismic qualification or verification that no
l
design or manufacturing changes had been trade.
l
l
6.
A Wilnar relay in the reactor coolant pump underpcwer protection
i
cabinet in the reactor coolant system was accepted without seismic
i
qualificottor, or verification that no design or ranufacturing changes
!
had been coce,
l
l
7.
Conn.ercially procurec Ohmite relays for the B norr.al battery charger
were received with a different configuration and accepted on the basis
'
of a *1ike-for-like" cetermination without seismic qualification
cocunentation or verification that no cesign or u.anufacturing changes
had been trade.

10.
A comercial grade of lube oil cooler for the high-pressure injection
and makeup pumps for the nuclear raw water system were purchased from
Basco mid accepted on the basis of a C of C without verification of
the validity of the C of C.
B.
Po'+ntial Enforcement Finding 50-312/88-02-02
The NRC inspectors found two instances of procurement of safety-related
items that did not include a requirement for the vendor to meet 10 CFR Part 21.
1.
The purchase of the five thousand feet of 5 kV power cable from NSSS/
DIVESCO, Inc., did not impose the requirements of 10 CFR Part 21;
however, generic test data performed to IEEE standards 383 and 323/324
was requested. This cable does not qualify as a commercial grade
item as defined by 10 CFR Part 21.
2.
Commercial grade replacement parts for Bnrgen-Patterson hydraulic
snubbers were procured during 1980 through 1985 and required a C of C
to nuclear specification (ANSI B31.7, "Nuclear Power Piping").
SMUC
never imposed the requirements of 10 CFR Part 21 on Bergen-Patterson.
It should also be noted that during the SMUD evaluation of their Class 1
items with green tags,11 of 75 purchase orders failed to impose 10 CFR Part 21 reporting requirements on the vendors as required.
C.
Potential Enforcement Finding 50-312/88-02-03
Safety-related procurements were made from vendors placed on the SMUD
approvcd supplier list (ASL) solely on the basis of desk audits of the
quality assurance (QA) manual.
Even after SMUD upgraded their process
for approving suppliers in late 1987, SMUD procedures still albwed
procurements to be made with no established time limits for performing
some form of proaram implementation evaluation.
This process could
potentially allow items to be procured and placed in service without the
vendor ever rec 61ving a QA program implementation evaluation.
Also, C of Cs for comercial grade procurements from vendors not on the
ASL were accepted without verification of their validity.
