NRC Office of Inspection and Enforcement; IE Supplement No. 3 to Bulletin No. 79-OlB, October 24, 1980 3.
NSP Letter to Director of Nuclear Reactor Regulation on January 1, 1980 Lessons Learned Implementation, March 13, 1980 IE Supplement No. 3 to Bulletin No. 79-OlB required submit'.al of qualification information for equipment resulting from TMI Action Plan requirements and equipment which is required to achieve cold shutdown.
Qualification Information for Installed TMI Action Plan Equipment Safety grade subcooling margin monitors have been installed in Unit 1 and 2.
The temperature input is derived from multiple core exit thermocouples and the pressure input is derived from Reactor Coolant System (RCS) wide range pressure. Outstanding items concerning qualification of the temperature and pressure inputs have been previously addressed in Reference 1.
Until the inputs to the subcooling monitors have been upgraded, the P-250 plant computer has been programmed to accept the best available temperature and pressure inputs; see Reference 3.
Qualification relating to components not previously addressed is reported in Attachment A of this response.
Qualification information for future TMI Action Plan equipment will be sub-mitted by the pre-implementation or implementation review date as required DOj by Reference 2, Supplement 3 to Bulletin 79-OlB.
- /
Equipment Required to Achieve Cold Shutdown The November 1, 1980 response to Bulletin 79-OlB has been reviewed to identify additional electrical equipment necessary to achieve and maintain a Cold Shutdown condition.

e b
Mr. James G. Keppler o
Page 2 January 22, 1981 The residual heat removal system, while not necessary, would, if available, normally be used to cool the plant to cold shutdown. Additional electrical equipment normally used would be the nonsafeguarda RHR suction valves from both RCS hot 1 cgs and the nonsafeguards loop B RHR return valve.
The environ-mental specification and qualification of these components is identified in Appendix A of this response. Outstanding items have been identified for specific accident related environmental conditions. NSP intends to continue investigation of these outstanding items.
In the event that the residual heat removal system components identified for
.cooldown are not available, the auxiliary feedwater system along with the secondary side power-operated relief valves would be used to bring the plant to a safe cold shutdown condition. The safety injection pumps and residual heat removal pumps, taking suction from the refueling water storage tank or containment sump, would be used to maintain reactor coolant system inventory.
Use of the steam generators as a forced cooling water heat exchanger at lower temperatures is discussed in FSAR Section I.8.
Yours truly, 0
