SUBJECT:
ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT RE:
YERMONT YANKEE NUCLEAR POWER STATION, FACILITY OPERATING LICENSE NO. DPR-28 Reference (a) - Order for Modifica. tion ofIicense Concerning the Environm ntal Qualification of Safety-Related Electrical Equipment dated October 24, 1980
Dear Mr. Smith:
i
.This letter transmits the Safety Evaluation for the Environmental Qualification of Safety-Related Electrical Equipment at your facility. This evaluation was based on your submittals dated June 2 and November 1,1980.
Our letter of February 20, 1981, which forwarded our preliminary results, indicated
. that an item-by-item re-evaluation would be required at a later date. This safety evaluation identifies the specific informatiort, required by the staff and the actions, on your part, necessary to comply with Reference (a).
We request that you provide the information identified in sections 3 and 4 'of this Safety Evaluation to us within 90 days.
This Safety Evaluation addresses only the safety-related electrical equipment exposed to a harsh environment resulting from an accident (i.e., the IEB 79-01B review).
Reference (a) requires that all safety-related electrical equipment be qualified by June 30, 1982. The NRC review effort for the equipment in mild environments will be addressed by separate correspondence.
Your response may presen,t alternatives to the staff positions in the evaluation.
The staff will consider alternative approaches if these methods are within
~.
the DDR Guidelines or NUREG-0588, as appropriate.
For example, an acceptable alternative to the NRC staff's. temperature criterion used for the service conditions (i.e. Section 3.3) must base that service condition on the FSAR analysis or other NRC approved analysis, provided that the specific analysis, together with reference to the previous NRC acceptance of that analysis, accompanies the 90 day response.
In addition, some of the information in the Safety Evaluatiorgay require clarification.
Co.ntact your project manager for assistance in these matters.

It temains your responsibility to assure that the qualification deadline is met 'for al1 ~ safety-related electrical equipment. The staff's review of your response to this letter'should not delay any action which is required in
. order to meet the deadline.

Sincerely,
[b Ippolito. Chief Thoma Operating Reactors Branch #2 Division of Licensing
