S. Nuclear Regulatory Commission Document Control Desk Washington, D. C. 20555 Gentlemen: Re: St. Lucie Units I and 2 Docket Nos. 50-335 and 50-389 Seismic Category I Piping Runs Between the Condensate Stora e Tank and the Auxiliar Feedwater Pum s By letter dated November IO, l986 (E. G. Tourigny to C. O. Woody), the NRC staff questioned the adequacy of the protection for the seismic Category I piping runs between the condensate storage tank and the auxiliary feedwater pumps passing underneath a non-seismic Category I structure, the turbine building. The staff postulated a collapse of the turbine building under a seismic event and was unable to confirm that the piping runs would be sufficiently protected. The following information is provided to assist the staff in its review of this issue. This concern was addressed during licensing of St. Lucie Unit 2 in response to NRC Question No. 4I0.38. As indicated in the response to that question, the basemat and steel superstructure of the Unit 2 turbine building was designed to withstand the effects of a Safe Shutdown Earthquake (SSE). The St. Lucie Unit 2 Final Safety Analysis Report, Section 10.4.9.3 reflects the above information. Regarding St. Lucie Unit I, the turbine building was reanalyzed for seismic loading in l975 to assure the integrity of the turbine building structure for the seismic loading condition. These buildings are not classified as Category I structures although they hove been designed to withstand seismic loads, as described above. Therefore, FPL does not postulate a collapse of either St. Lucie turbine building during a seismic event,
- and, as a
- result, there is no potential for interaction between the seismic Category I piping runs and the non-seismic Category I turbine buildings.
