Gentlemen:
Subject: NRC Region I Inspection No. 50-336/89-24
This refers to the routine resident safety inspection condv ced by
Mr. P. Habighorst of this office on December 5,1989 - January 19, 1990, at
Millstone Nuclear Power Station, Unit 2, Waterford, Connecticut, of activities
authorized by NRC License No. DPR-65 and to the discussions of our findings
held by Mr. Habighorst with Messrs. S. Scace and J. Keenan of your staff at the
conclusion of the inspection.
Areas examined during this inspection are described in the NRC Region I
inspection report which is enclosed with this letter. Within these areas, the
inspection consisted of observation of activities, interviews with personnel,
measurements and document reviews.
Based on the results of this inspection, it appears that one of your activities
was not conducted in full compliance with NRC requirements, as set forth-in the
Notice of Violation enclosed herewith as Appendix.A.
The licensee-identified
violation involved operation of the facility in cold shutdown for a period of
29 hours3.356481e-4 days <br />0.00806 hours <br />4.794974e-5 weeks <br />1.10345e-5 months <br /> without an operable containment gaseous and particulate radiation
monitor. You reported this event in Licensee Event Report (LER)89-009.
This
violation has been categorized by severity. level in accordance with the
" General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy). You are required to respond to this
letter and in preparing your response, you should follow the instructions in
Appendix A.
In review of the apparent violation, NRC inspection identified two deficiencies
not recognized or reported in LER 89-009; specifically, the failure to identify
an-additional technical specification limiting condition for operation appli-
cable to the event; and secondly, an inaccurate time interval for the
out-of-service radiation monitors. Our independent review determined that a
plant vulnerability existed based on plant decay heat rate and reduced
inventory operation at the time of the event. Therefore, in your response to
this letter .you are requested to address LER accuracy and your assessment of
plant vulnerability during the event.
