Dear Sir:
Subject:
Environmental Qualification of Electrical Equipment In reference (b), each SEP license was asked to perform a review of their safety related electrical equipment against the guidelines furnished in that letter. YAEC has already completed an extensive review of its safety related equipment and submitted this review in Reference (c). The review was subsequently updated and resubmitted in Reference (d). We have not received any comments from the NRC on the contents of this report and feel that it had adequately addressed all the concerns for environmental qualification of electrical equipment and met the guidelines provided.
In response to the request of Reference (e), we have reviewed the previously submitted equipment list using the new guidelines furnished in Reference (e).
Enclosure A is the new master equipment list which takes into account the new guidelines for identifying electrical equipment and incorporates equipment added or changed as a result of system modifications made at the Yankee Rowe Plant since the earlier submittals. Equipment added strictly in response to TMI Lessons Learned Short Term Requirements and audited by the TMI review team has not yet been listed but will be included in the next revision.
In reference (f), we submitted the data necessary for the calculation of the containment pressure and temperature decay time as requested in Enclosure 2 of Reference (b). Enclosure 3 of Reference (b) requested information necessary for review of plant spccific containment analyses. This information is provided in Enclosure B of this letter. This scoping analysis is being used in determining the service environments for equipment inside the containment until a more detailed analysis is performed as discussed in Enclosure B.

Att:nticna Mr. Dennis M. Crutobrisld, Chict Paga 2 For high energy line breaks (HELB) outside the containment, we have submitted in Reference (g) a supplementary report on the effects of pipe breaks outside the containment. This report did not address the environmental effects of such breaks. To address these effects, our approach is to identify the breaks that can affect the safety related equipment required to mitigate the consequences of the break from an environmental viewpoint. In such cases, we are planning to implement localized leak detection in conjunction with in service inspection to give advanced warning of impending pipe breaks. This would allow the plant operators sufficient time t6 bring the plant to a stable condition prior to a possible line break. This el'iminates the need to perform a detailed analysis of the environmental effects of a line break outside containment and to qualify electrical equipment to withstand the effects of this environment.
We have obtained the service of two outside consultants to assist us in evaluating the ability of the electrical equipment listed in Enclosure A to withstand the doses from recirculating fluids outside the containment after a LOCA and to evaluate the effects of aging on electrical equipment. We are analyzing the effects of the doses to mechanical equipment from recirculating fluids as noted in Reference (h). We have obtained preliminary schedules from these consultants for the time required to perform this work. According to these schedules, the analysis of in-containment equipment will be completed in September 1980, based on timely completion of the consultant's work, adequate and timely response from manufacturers, and YAEC review of the results. For equipment outside containment, we expect the analysis to be completed in December,1980, again based on the timely completion of the consultant's work, adequate and timely response from manufacturers and YAEC review of the results.
We trust you will find this information satisfactory.
However, if you have any questions, please contact us.
Very truly yours, s_l\\
