SUBJECT:
ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT RE:
DRESDEN STATION UNIT NO. 3, LICENSE NO. DPR-25 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 Ev al uatf on for the Environmental Qual i fiCatf on.
of Safety-Related Electrical Equipment at your facility. This evaluation was based on your submtt.t.a.L tf..a.te..d.. ~Jo.vember 1, 1980-.
Our 1 etter of t'.pri l 1, 1981, which fontarded our prel1m1nary-results, indicated that an item-by-;tem re-evaluation would be required at a later d_ate.
This safety evaluation identifies the specific information required *by the staff and the actions,* on your part, necessary to comply with Reference {a).
We I request that you provide the i nfor-mat1 on identified in sections 3 and 4 of this Safety Evaluation to us within 90 days.
This Safety Evaluatiol'\\ addresses only the safety-related electrical equipment exposed to a harsh environment resulting from an accident (1.e., the IEB 79-018 review).
Reference {a) requires that all safety-related electrical equipment be qua11fied by June 30, 1982.
The ~JRC review effort for the equipment in mild environments wi 11 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 (1.e. Section 3.3) must base that service condition on the FSAR analysis or other ~JRC approved analysis,.provf ded that the specific analysis, together witti reference to the previous NRC acceptance of that analysis,
_ accompanies the 90 day response.
In addition. some of the 1nfonnat1on *in the Safety Evaluation may require clarification. Contact your project manager for assistance in these matters.
