DeYoung The acceptability of the design End' any additional information relating ~ to the pitimate haat sink and plant flood protectica capabilities will be dependent upor the final results of the applicant's nodal for the Probable Maxieum Hurricane, the Site Analysis Branch (hydrology) receipt of outstanding information, and a site visit achedulad for the last half of July. One area where difficulty may ba ancountered during the review and will require a aseting with ths' applicant, relates to the acceptability of the design of the nuclear services cooling water system and the nuclear servica elesed cycle cooling water system with respect to its capabilities to withstand the effects of a single active or fassive failure so that long tarned post-accident cooling will be assured. ~ Robert L.
