Docket No. 50-336
Mr. John F. Opeka
Executive Vice President - Nuclear
Northeast Nuclear Energy Company
P.O. Box 270
Hartford, Connecticut 06141-0270
Dear Mr. Opeka:
SUBJECT: MILLSTONE UNIT 2 INSPECTION 50-336/93-18
This refers to the special inspection conducted by Mr. P. Swetland and Mr. D. Dempsey of
this office on August 2 through September 17,1993, at Millstone . Unit 2 in Waterford,
Connecticut. During this inspection we reviewed your repair activities with regard to a
body-to-bonnet leak on a letdown system isolatian valve which was not isolable from the
reactor coolant system. On August 5,1993, excessive leakage from this valve forced a
shutdown of Millstone Unit 2. The inspection findings were discussed with Mr. S. Scace,
the Unit 2 Director, and others of your staff at the conclusion of the inspection, and are
described in the enclosed report.
Based on the results of this inspection, three apparent violations were identified and are being
considered for escalated enforcement action in accordance with the " General Statement of
Policy and Procedure for NRC Enforcement Actions" (Enforcement Policy),10 CFR Part 2,
Appendix C (1992). The violations involved failure to provide adequate repair instructions
and to properly implement existing guidance for the repair of the valve; failure to perform a
safety evaluation of the changes made to the valve during the repair activities; and failure of
l
your quality programs to assure conformance with documented instructions and procedures -
for the repair. The quality of preparation and implementation of this repair activity was not
commensurate with the safety significance of this nonisolable leak from the reactor coolant
system.
)
!
f
We are concerned that the errant repair activities continued over an extended period without
intervention by either management or the engineering organization. In addition, the fact that
these activities continued despite frequent observation by your quality services inspection and
surveillance personnel is considered to be a breakdown in your quality assurance program.
Accordingly, no Notice of Violation is presently being issued for these inspection findings.
l
Please be advised that the number and characterization of apparent violations described in the
g
l
enclosed inspection report may change as a result of further NRC review.

An enforcement conference to discuss these apparent violations has been scheduled for
October 1,1993. This enforcement conference will be open to public observation in
accordance with the Commission's trial program as discussed in the enclosed Federal
Register Notice (Enclosure 2). The purposes of this conference are to discuss the apparent
violations, their causes and safety significance; to provide you the opportunity to point out
any apparent errors in our inspection report; and to provide an opportunity for you to present
your proposed corrective actions. In addition, this is an opportunity for you to provide any
information concerning your perspective on 1) the severity of the issue, 2) the factors that the
NRC considers when it determines the amount of a civil penalty that may be assessed in
accordance with Section VI.B.2 of the Enforcement Policy, and 3) the possible basis for
exercising discretion in accordance with Section VII of the Enforcement Policy. You will be
advised by separate correspondence of the results of our deliberations on this matter. No
response regarding the apparent violations is required at this time.
