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) 1

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.

Mr. C. E. Larsen

.

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

PINGP.

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.
