Mr. Thomas J. Kovach Nuclear Licensing Manager Conunonwealth Edison Company Post Office Box 767 Chicago, IL 60690
Dear Mr. Kovach:
SUBJECT:
SAFETY EVALUATION REGARDING COMPLIANCE WITH 10 CFR PART 50, APPENDIX R, ITEMS IIIiG~3 AND III.LAND EXEMPTION REQUEST FOR HOT SHUTDOWN REPAIRS FOR DRESDEN UNITS 2 AND 3 (TAC NOS. 59853 AND 59854)
By submittals dated September 10 and November 17, 1987, and March 15, April 19 July 13, and September 16, 1988, you further revised your Appendix R compliance program at Dresden regarding Items III.G.3 and III.L {alternative/dedicated shutdown capability} which was previously approved by the staff in a Safety Evaluation issued July 17, 1987.
As discussed in the enclosed Safety Evaluation, we have determined that the revised alternative shutdown capability for Dresden Units 2 and 3 meets the requirements of Appendix R, Item III.G.3 and the performance goals of Item III.L and is, therefore acceptable.
In addition, your request for exemptions from the Appendix R, Item III.G~l requirement for performing proposed hot shutdown repairs is also granted.
\\
In this context, we note that a few of the proposed manual.actions require completion within a very short time after scram (e.g., replacement of blown controlpower fuses for the swing diesel generator starting controls, removal of 20 control power fuses for reactor relief valves, and engaging the automatic blowdown inhibit switch prior to evacuating the control room for a fire in the control room).
We will request that the Region verify your ability to perform the identified short-term hot shutdown repairs in a timely manner.
