Mr. P. C. LeBlond:
Subject:
C & 5 Valve Company Allegations Confirming our conversation of 1/4/88, the following summarizes the facts obtained in QA's investigation of materials received from C & S Valve Company, and presents our conclusions.
1.
Utilizing the Purchasing data base (PIC), we established that there were 18 apparent purchase orders to this firm, dated from 8/20/84 through 9/15/87.
2.
C & S was not an approved supplier (for safety-related purposes),
on its own, to Edison until the Fall of 1985.
Earlier dates on purchase orders undoubtedly reflect orders placed with Clow Corporation, which yas an approved source, and subsequently transferred to the new entity. He did not analyze P.O.'s Nos. 295177 and 751649 because their dates put them in this category.
P.O. #289825 dates from the same period but yas analyzed because data was still available.
3.
For the 16 P.O.'s analyzed, the status is as follows:
- 8 were non-safety.
- I was concercial orad >.
- 7 were safety-related.
4.
Ccmmercial grade P.O. #313311 was for a LaSalle sealed stack assembly which was receipt-inspected with no deficiencies, and was dedicated and put in safety-related service at the Station.
I
<=-r r_c-w m.

5.
The seven safety-related P.O.'s break down as follows:
Station Comment 310782 Zion Cancelled due to this allegation.
306208 Quad Cities Cancelled due to alternative source.
759144 Quad Cities Turbine exhaust check valve, orig. mfr.
TRW Hission, rebuilt by C&S; document problems on receipt resulted in HOLD; specifica.tlon revision in progress as of 1/6/88.
311524 LaSalle Parts for RHR pump discharge check valve.
Thoroughly receipt inspected, no deficiencies; apparently installed.
306901 LaSalle Shop repair of 10 large valves (VQ isolation). Receipt inspected, installed, tested after installation, and entire installation walked down by Sargent & Lundy team.
303307 Quad Cities HPCI turbine steam exhaust check valve (see 759144), spare, in storage at Station; source-inspected by Quad Cities QC, including hydro & pneumatic tests, and receipt inspected at Station -- no deficiencies.
755205 Byron Resilient seat only, for TRW Hission dual-plate check valve. Receipt inspected, instelled about 10/86, full operational tests.
6.
Recelps inspection data was sittsfactory physically in all cases and, in four of the five safety-related purchases which were actually completed, operational data, functional tests, or factory test data, the latter witnessed by Edison, is available to support proper candition and function of the subject valves or
- parts, r
w 7.
QA believes that these data provide adequate confidence that the purchased items were in accordance with applicable specifications and are providing, or will provide, satisfactory service.
Further, QA and QC Involvement with these items has identified no i
indication of physical defects or deficiencies which might be attributable to the alleged omissions / commissions at the
, manufacturer. Indeed, the only problems reported in any instance l
were those of missing documentation as to P.O. #759144, which is in the process of correction.
8.
Further, QA condccted a routine audit of the manufacturer l
(G-87-204) in March, 1987, (report copy attached), which covered, inter alia, equipment calibration; handling, storage, shipping, and product tJ4ntification; material storage; in-process documentation; and treatment of nonconforming items, all of which involved in-plant observation and/or inspection. No deficiencies in practices or adherence to commitments were noted in these areas during this audit; the sole deficiency on the audit related to documentation and follow-up of internal audits, and an open ltem identified a lack of clarity in personnel qualification 4
documents. Both 1tems were addressed promptly by C & S and the results were acceptable; this audit has therefore been closed.
While this audit was not specifically directed at the conditions alleged, QA believes that evidence of such problems, if pervasive, alght well have been detected by this audit. Such evidence was not noted.
He trust that this summary will provide adequate material for your communications with NRC. If you need additional information, please contact me.
