Docket No. 50-271
Vermont Yankee Nuclear. Power Corporation
ATTN: -Mr. Warren P. Murphy
Vice President and Manager of Operations
RO 5, Box 169
Ferry Road
Brattleboro, Vermont 05301
Gentlemen:
Subject:
Inspection Report No. 50-271/86-05
This refers to the special inspection conducted by Messrs. W. J. Raymond and
G. W. Meyer of this office on February 9-27, 1985, at the Vermont Yankee Nuclear
Power Station, Vernon, Vermont. . The inspection was performed as a result of the
Standby Liquid Control (SLC) system test failure on February 8, 1986.
The inspec-
tion findings were' discussed with Mr. J. Pelletier of your staff at the conclusion
of the inspection.
Our review of the circumstances associated with the SLC system test failure indi-
cates the system was inoperable from July 11, 1984 until testing on February 8,
1986 due to an unintended change in the squib primer wiring by the vendor.- We are
concerned that your procurement program and post-installation testing program did
not detect a product change that affected the operability of a safety system. We
are also concerned with an unapproved change which you made to the squib firing
circuit..
The apparent violation identified in our review of this event is discussed in the
enclosed report.
The need for and nature of appropriate enforcement action rela-
tive to the apparent violation will be the subject of separate correspondence at
>
a later time.
These matters will be discussed in an enforcement conference with
,
}
you and members of your staff scheduled for March 19, 1986.
You should come to
the meeting prepared to discuss ~your understanding of these events and your planned
and implemented corrective actions,
i
In accordance with 10 CFR 2.790 a copy of this letter and the enclosures will be
placed in the P'RC Public Document Room.
.
Your cooperation with us is appreciated.
