November 17, 1993 Docket No. 50-382 Mr. Ross P. Barkhurst Vice President Operations Entergy Operations, Inc.
Post Office Box B Killona, Louisiana 70066
Dear Mr. Barkhurst:
SUBJECT:
INSTRUMENTATION TO FOLLOW THE COURSE OF AN ACCIDENT (REGULATORY GUIDE 1.97) - WATERFORD STEAM ELECTRIC STATION, UNIT 3 Section 6.2 of Generic Letter 82-33 requested licensees to provide a report on their implementation of Regulatory Guide 1.97 (Revision 2), including their methods for complying with the Commission's regulations and a supporting technical justification for any proposed alternatives or deviations. A large number of exception requests were received from pressurized-water reactor licensees asking that the environmental qualification requirement for accumulator level and pressure monitoring instrumentation be relaxed from Category 2 to Category 3, allowing commercial grade instruments to be used.
Prior to 1987 these requests were denied by the staff. Since then, these exceptions have been considered as an open item until a generic resolution can be found.
The staff has now reviewed the bases for these exceptions and has concluded that no operator action is based on this post-accident instrumentation and that this instrumentation does not perform any post-accident safety function.
Accordingly, its qualification requirements can be reduced to Category 3.
A copy of our Safety Evaluation is enclosed.
You have already installed Category 2 instrumentation to monitor accumulator level and pressure.
You are no longer bound by this commitment and may, at your discretion, replace this instrumentation with Category 3 instrumentation.
This letter constitutes prior approval for use of Category 3 instrumentation.
to monitor accumulator level and pressure at the Waterford Steam Electric Station, Unit 3.
