SUBJECT:
INSPECTION OF THE VENDOR INTERFACE AND PROCUREMENT PROGRAMS
AT THE PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNITS 1 AND 2
(INSPECTIONREPORT.NOS.: 50-282 & 306/88-201)

Dear Mr. Larsen:
This_ letter transmits the report of the' inspection conducted October 25 through'
]
~
November 4, 1988,~at the Prairie Island Nuclear Generating Plant (PINGP),: Units
'
1 and 2, by Messrs. R. P.- McIntyre, R. L. Pettis
S. D. Alexander, and.
'
.W.P..HaassoftheNRCVendorInspectionBranch(VIB). The inspection was
.
related to plant site activities authorized by NRC License-Numbers DPR-42 and
DPR-60. At the conclusion of the-inspection, our. findings were. discussed with.
j
Mr. Leon Eliason, General Manager, Nuclear Power Plants, and the members of your
'
1 staff identified in Appendix.A of the enclosed inspection report.
1
The purpose of the inspection was to review the implementation of the PINGP
i
vendor interface program and the programs for the procurement of items for use
1
in safety-related applications. The: inspection team reviewed the documentation
of specific vendor-related technical issues,-including 10 CFR.Part 21 notifi-
i
cations received at PINGP, and documentation concerning the procurement of bothL
!
safety-related and commercial grade items, either installed in the plant or
,
stored in the warehouse.
,o
'
The results of the inspection indicate that weaknesses exist in the areas of
procurement and dedication of commercial grade items and interfaces between
' Northern States Power Company (NSP)/PINGP and its vendors. During review of
the procurement program and procedures, the inspection team identified signi-
ficant' deficiencies in the procurement of commercial grade-items for eventual
use.in safety-related applications. The deficiencies included the failure to
properly dedicate _and provide documentation for commercial grade items procured
for use .in safety-related applications.
PINGP failed to perform documented
technical evaluations to identify attributes such as the components' safety
functions and critical characteristics, verifications of design and manufactur-
ing/ material changes, and receipt inspection requirements beyond, generally,
,
a part number verification.and a check for physical damage and cleanliness.
This resulted in the utilization of numerous components of indeterminate
quality and qualification in safety-related applications.

The review of the PINGP vendor interface program indicates the need for
improvement, especially as related to the level and depth of the assessment of
communications from the NRC and vendors and the evaluation and implementation of
corrective action on service and maintenance recommendations received from Colt
Industries /Fairbanks Morse Engine Division (FMED).
PINGP failed to perform
documented assessments of 17 Colt /FMED Service Information Letters (SIL's) for
1
their applicability to the PINGP emergency diesel generators. One SIL, dated
April 27, 1988, had not been received and therefore, had not been evaluated by
The review of the vendor interface program also identified a weakness in which
certain vendor communications received at PINGP describing potential safety
!
concerns were improperly and incompletely assessed for their applicability to
PINGP. The inspectors also identified several assessments that lacked the
necessary level of documentation to permit clear understanding of the disposition.
The inspection findings discussed above and in the enclosed report have been
classified as Potential Enforcement Findings 50-282 & 306/88-201-01, 02, and 03
(Enclosure 1). These will be referred to the NRC Region III office for appro-
priate action.
We acknowledge the receipt of your letter, dated January 9,1989, wherein you
described your plans for reviewing a representative sample of installed commer-
cial grade parts using a new dedication process based on EPRI-5652, and for the
implementation of this process for all commercial grade parts purchased after
.
November 4, 1988.
!
Should you have any questions concerning this inspection, we will be pleased
to discuss them with you.
Sincerely,
}?

POTENTIAL ENFORCEMENT FINDINGS
Northern States Power Company
Docket No.: 50-282 & 306
Prairie Island Nuclear Generating Plant
Licensee Hos.: DPR 42 & 60
<
During the period of October 25 through November 4,1988, representatives of
l
the NRC's Vendor Inspection Branch reviewed the vendor interface and procurement
j
programs of the Prairie Island Nuclear Generating Plant (PINGP). As a result of
1
the inspection, and in accordance with the " General Statement of Policy and
l
Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986), the
-
NRC inspection team identified the following potential enforcement findings:
A.
Potential Enforcement Finding 50-282 & 306/88-201-01
The NRC inspectors identified numerous examples where the licensee installed
commercial grade items (CGI's) in safety-related systems without adequately
evaluating their suitability for use in such applications.
CGI's were
a
procured without performing technical evaluations to identify attributes
such as the components'/ items' safety functions and critical characteris-
tics.
No verification of design and manufacturing / material changes, and
receipt inspection requirements beyond a part number verification and a
check for physical damage and cleanliness was performed. This program-
matic deficiency resulted in the installation of numerous components of
.'
indeterminate quality in safety-related systems.
The examples identified by the inspectors are listed in Section I.B.2 of
the inspection report.
B.
Potential Enforcement Finding 50-282 & 306/88-201-02
The NRC inspectors determined that the licensee failed to comply with
PINGP Procedure SACD3.7, " Operating Experience Assessment," for the evalu-
ation and implementation of recommended actions given in 17 Service
Information Letters (SIL's) received from the emergency diesel generator
(EDG) manufacturer, Colt Industries /Fairbanks Morse Engine Division (FMED).
The SIL's were not evaluated properly or in a timely manner for their
applicability to the PINGP.
Furthermore, appropriate pen-and-ink changes
to the governing maintenance and operation manuals for the D1 and D2 EDG's
were not made.
SIL A-17, dated April 22, 1988, was not received by the licensee and thus
the recommended SIL modifications were not made to the D1 and D2 EDG's.
C.
Potential Enforcement Finding 50-282 & 306/88-201-03
The NRC inspectors identified several NRC and vendor communications
describing potential safety concerns that were received at PINGP, but were
improperly and/or incompletely assessed for their applicability to PINGP.
3
Also, the depth of the documented assessments in many cases was at a
'
level that did not enable the inspectors to make a clear determination of
the adequacy of disposition of the issue. The examples identified by the
inspectors are listed in Section III.C. and III.E of the inspection report.
