J' UL 111986
Docket No. 50-29
Yankee Atomic Electric Company
ATTN: Mr. L. H. Heider
Vice President Of Operations
1671 Worcester Road
Framingham, Massachusetts 01701
Gentlemen:
Subject: Inspection No. 50-29/86-09
This refers to the special inspection conducted by Mr. H. Eichenholz of this of-
fice on June 26 - July 2, 1986, at the Yankee Nuclear Power Station, Rowe, Massa-
chusetts.
The inspection was performed as a result of your discovery on June 26,
1986 that the Reactor Coolant System Vents (RCSV) and Emergency Feedwater (EFW)
System motor operated valves were inoperable.
The inspection findings were dis-
cussed with Mr. N. St. Laurent of your staff at the conclusion of the inspection.
Our review of the circumstances associated with the identified deficiencies indi-
cates that the RCSV and the EFW System were inoperable from November 27, 1985 until
June 26, 1986 due to the installation of undersized trip coils in the combination
breaker / starters for valves EBF-MOV-557, PR-MOV-558, VD-MOV-559, and PR-MOV-560.
We are concerned that (1) your procurement and post-installation testing programs
did not detect the inclusion of an incorrect device that affected the operability
of these safety systems, and (2) that this specific issue may be symptomatic of
4
a broader problem.
As a related matter, we are also concerned that you apparently
have not provided sufficient resources and training to site engineering personnel
involved with the above programs as recommended in our most recent SALP report.
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 July 22, 1986 at 9:00 a.m. in the
Region I office. You should come to the meeting prepared to discuss your under-
standing of these events, the reasons that they occurred, and your planned and
completed corrective actions.
Your cooperation with us is appreciated.
Sincerely,
Original S1BD80 3Y'
William F. Kane, Deputy Director
Division of Reactor Projects
