SUBJECT:
ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT RE:
QUAD CITIES STATION UNITS 1 AND 2, FACILITY OPERATING LICENSE H0S. DPR-29 AND DPR-30 Reference (a) - Order for Modification of License Concerning the Environmental Qualification of Safety-Related Electrical Equipment dated October 24, 1980
)
Dear Mr. Abel:
This letter transmits the Safety Evaluation for the Environmental Qualification of Safety-Related Electrical Equipment at your facility. This evaluation was based on your submittal dated November 1,1980. Our letter of March 17, 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 information required by the staff and the... actions, on your part, necessary to comply with Reference (a). We request that you provin the informa-tion 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 present alternatives to the staff positions in the evaluation.
The staff will consider alternative approaches if these methods are within the DOR 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 FSAP, analysis or other NRC approved analysis, provided that the specific analysis, together with reference to the previous HRC acceptance of that analysis, accompanies the 90 day response.
In addition, some of the information in the may require clarification. Contact your project manager for Safety Evaluation,Tmatters.
