Dear Mr. Stolz:
Ihe desire for additional information concerning the design requirements for the Borated Water Storage Tank (BWST) was identified in discussions held on September 21, 1976 between Mr. E. C. Novak, Toledo Edison General Superintendent, Power Engineering and Construction, and Mr. Leon Engle, NRC Licensing Project Manager. That following information is provided, and will be incorporated into section 6.3.3.2 in the next revision to the FSAR, tentatively planned for October 15, 1976. We understand that this advance information will allow timely disposition of this review item.
The BWST is not required to take the Davis-Besse Unit 1 to cold shut-down following a postulated tornado. In going to cold shutdown, the reactor coolant contracts 3166 cubic feet. This " void" can be filled with water which is available from the boric acid addition tank, the makeup tank, the core flood tanks and the pressurizer, all located within seismic Class I, tornado protected structures.
Yours very truly,
/
