VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 NORTH ANNA POWER STATION UNITS 1 AND 2 RESPONSE TO NRG BULLETIN NO. 88-05, SUPPLEMENTS 1 AND 2 BACKGROUND Serial No.
NO/HWB:vlh Docket Nos.
License Nos.88-282 Rl 50~280 50-281 50-338 50-339 DPR-32 DPR-37 NPF-4 NPF-7 NRG Compliance Bulletin 88-05, issued May 6, 1988, requested licensees to review their purchasing records to determine if they procured material from Piping Supplies, Incorporated (PSI) and West New Jersey Manufacturing Company (WJM).
It also requested that actions be taken to assure that material purchased from these suppliers either comply with ASME Code and design specifications or that it be demonstrated that the material is suitable for its intended service or that such material be replaced.
The period for this records review was to cover January 1, 1985 and January 1, 1976 to the present for PSI and WJM, respectively.
Supplement 1
to Bulletin 88-05, issued June 15, 1988 provided additional information on material supplied by PSI and WJM and reduced the scope of the review to flanges and fittings.
It also delineated actions that licensees should take to determine whether the materials complied with ASME and ASTM design and material specifications and clarified what actions licensees were requested to tak~ once they identified nonconforming material.
Supplement 2 to Bulletin 88-05, issued August 3, 1988, modified the schedule for requested actions identified in Bulletin 88-05 and in Supplement 1 and provided further information on materials supplied by
- PSI, WJM and by a
recently identified company, Chews Landing Metal Manufacturers Incorporated (CLM).
For licensees with operating units, Supplement. 2 also suspended, as of August 3,
. 1988, record review, testing, analysis efforts requested by the initial Bulletin and by Supplement 1.
The 120 day reporting requirement remained unchanged.

The following is a summary of the actions taken by Virginia Power in response to NRC Bulletin 88-05 and to Supplements 1 and 2.
REVIEW FOR POSSIBLE DIRECT PURCHASES The current Virginia Power vendors list, initiated in 1980, was reviewed to determined if any material had been purchased directly from PSI and WJM.
This review showed that neither WJM nor PSI were approved for safety-related purchases.
Betwee*n 1976 and 1980 the Virginia Power vendors list was in the process of being compiled.
During this time, vendors were typically added to the list and not deleted.
Therefore, it can be reasonably concluded that the 1980 list also encompasses those vendors used between 1976 and 1980.
To provide added assurance that no material was purchased directly from WJM or PSI, a review of accounting records was conducted.
. Available Virginia Power accounting records date back to 1977.
Neither PSI or WJM were identified in our records.
Virginia Power purchasing activities were supported through contracts with our primary Architect Engineer, Stone & Webster Engineering Corporation, during the mid to late seventies.
Neither WJM or PSI were on their approved safety-related vendors list during that time.
Based on these reviews of our vendors lists, accounting records and the Stone &
Webster vendo_r list, it can be concluded that no material was purchased directly from WJM or PSI.
REVIEW FOR POSSIBLE INDIRECT PURCHASES Virginia Power contacted the suppliers of safety related material who may have used WJM or PSI as a subsupplier.
This search was limited to safety related procurements since there is no requirement to provide documentation from subsuppliers on non-safety related equipment.
Each manufacturer was asked if they had used PSI or WJM as a subsupplier on Virginia Power orders.
Of the 213 vendors contacted, 153 (72%) confirmed that no materials had been purchased from either PSI or WJM and supplied to Virginia Power; 36 (17%) of the suppliers were not located and; 23 (11%) responded with uncertainty.
One manufacturer responded positively and provided the corresponding p*urchase order numbers.
For those who were not located or who responded with uncertainty, an accounts payable search was conducted to produce a listing of paid purchase orders.
These documents were to be retrieved from storage and reviewed to determine if PSI or WJM was used as a
subsupplier when efforts for the Bulletin response were suspended in accordance with Supplement 2.
TESTING AND ANALYSIS RESULTS In the case of the vendor who_did provide purchase order numbers, the associated purchase documentation was pulled and the material identified.
A total of eight pieces were procured from PSI through Consolidated Power Supply.
One piece was located in a non-safety related system at North Anna while the other seven were st~ll in storage.
All eight pieces have been tested.
I' Five of the eight pieces were two inch raised face blind type flanges.
The five yielded test results which indicated that the material is marginal and questionable.
Four of the five exhibited a macrostructure that indicates they were fabricated from plate and not forged as required by ASME SA-105.
One of the five exhibited a significant difference in copper content from the others indicating that it was not from the same heat as claimed.
The remaining three flanges are of the three inch raised face socket weld type.
Two of these three were available from the warehouse and produced laboratory test results which indicated they do meet the specification.
The final piece was tested in place using the Equotip hardness tester.
These test results indicated that the temperature correction factor supplied by NUMARC, used to determine an equivalent tensile strength may be sensitive to differences between different heats of material on different product forms.
Using the two pieces of the same heat removed from the warehouse, temperature correction factors were generated by Virginia Power.
Chemical analysis of a material sample, and application of the correction factors for temperature and orientation confirmed that the installed material, also met the specification.
Detailed results of this testing have been supplied to Bechtel Power Corporation for incorporation into the NUMARC database.
The information provided in this response is true and accurate to the best of my knowledge.
If additional information is required, please let me know.
