Subject:

Calvert Cliffs Nuclear Power Plant Units No. 1 & 2, Docket No. 50-317 & 50-318 Fire Protaction Safety Evaluation Report and Amendments to Facility Operating License File: 013-261-0, L-037-F

Reference:

1) NRC letter dated September 14, 1979 from Reid to Lundvall, same subject
2) BC&E letter dated November 13, 1979 from Lundvall to Reid, same subject Centlemen:

The referenced Baltimore Gas and Electric Company letter dated November 13, 1979 advised that we would furnish later under separate cover responses to items 3.1.19, 3.1.20, 3.2.1, 3.2.2, 3.2.8, and 3.2.9. We had anticipated that this information would be forwarded in November. On November 14, 1979, we met with your staff to discuss our proposed ASTM E-119 test procedure to qualify asbestos braid jacketed, silicone rubber insulated cable for use in safe shutdown systems without further modification. However, by telephone notification on November 20, your Mr. E. L. Conner, Jr. advised that our modified procedure for fire testing conduit having silicone rubber insulated wires would probably not satisfy the concerns of the NRC Fire Pro-tection Staff.

This has necessitated a major revision to our Fire llazards Analysis and documentation.that we had essentially completed. We are now in the process of preparing new drawings and room-by-room documentation to reflect wrapping and other alternative actions to support our Fire llazards Analysis. We antici-pate we will now furnish the revised submittals by December 21, 1979.

Very truly yours, [
