Boston Edison System Maintenance Pilgrim Nuclear Power Station Bechtel Job No. 17849 Bechtel Purchase Order #15086-FN-68090 BIW Order #5D120 10 CFR 50, Part 21 Notification
Dear Dr. Murley:
On October 29th, verbal notification was provided to Mr. J. Strossnider of the N.R.C. regarding material located on-site which was determined to be nonconforming by BIW Cable Systems, Inc. personnel.
In July of 1985, sixteen (16) reels of Bostrad 7E, 600 volt instru-mentation cable consisting of a single twisted shielded pair of #16 AWG and designated by BIW P/N 13285-H-002 was shipped against the above referenced order. The total amount of cable being approximately seventy-five thousand (75,000) feet.
On October 14.-1986, I was notified by a Ms. S. Novak of Boston Edison that Bechtel had issued two nonconformance reports (i.e. Nonconformance Report #674 and #675) against cable presently being installed and was asked if BIW would provide assistance in evaluating the problem.
The Q.C. Manager of bid's North Dighton/Taunton facility, Mr. John Bohn, was on-site within twenty (20) hours of the initial call and his evaluation indicated that two areas of the nonconformance reports related to handling during installation.
(i.e. broken conductor wires due to extreme tensile force and nick in insulation unrelated to the manufacturing process). The sample showing the nick in the insulation, however, did display a nonuniform insulation wall thickness and was taken back to BIW for dimensional analysis.
It was determined that the minimum wall thickness requirement was not being met and BIW recommended that this reel identified as reel #09, be removed from service.
On October 22nd, samples representing all the reels supplied were obtained for the purpose of both dimensional analysis and physical testing.
In the course of ths investigation, it was determined that the following reels contained noncomforming material and Boston Edison was advised verbally that we recommend that cable from these reels be withdrawn from service. These reels are identified as reel #01, #02,
- 09, #10, and #15.
