darold L. Prica Director of Regulation Peter A. Morris, Director Division of Reactor Licensing FLORIDA POW.a CORPORATION'S CONSTRUCTION EXDiPTION REQUEST DOCKET NO: 30-302 By letter dated February 14, 1968, the Florida' Power Corporation requested en exemption from the provisions of Section 50.10(b), pursuant to Section 50.12 of the Co= mission's rules to permit construction of the tendon gal-1ery for the Crystal River Unit 3 Nucient Generating Plant prior to issuance of a construction permit. Supplccental information on power margins was furnished by the Florida Pcver Corporation in a suppic-ental icetar dated April 18, 1968.
The tendon gallery installation is required in order to accomplish pouring of a concrete leveling mat helev the base slab of rne reactor building, aractica of for as md the Icoac place.:ent cf reinfu c uent ateel for the bct:.nin of the reactor building.
The e,s11ery u a reinforced concrete pc:: cage located below the contcinrent Eu11 ding b ua alnb hut does net function sa support for the buildin. 'Ihc gallery is pr.rridcd to pernit inctallatica of tha contcierrent building practreasing tendcas and periodic i"aapection of the tc.!denB.
Tha applicant % basis for perfornia the requectad construction is that the ;;allery docs not function as a safety f2atu:a of the containment
'mtiding and that delaying M the placing cf the gallery vould dcIny the overall construction of the facility, i
Our review of the exc~:ption ree.ucs indicates that although the tendon gallery is a ftmetional part of the centainrent building from the view-point of installation and inspection of the prostressive tendens, it does not serve as a structural foundation.. The geological censiderations for i
the Crystal River site have been reviewed.
It has been deter =ined that the subsurface grouting, referri.C to in the applicant's requent for exerp-tion and his PSAR, provides an. acceptable foundation.in the native lime-stone. We conclude that., installation'of the tendon gallery would not present a safety problem, and therefore we have no objection to granting the request.
The applicant states in his supple cnts1 Icteer that by smvr 1972 ene peak power load Ivill: be 1861 W and the generation capacity exclusive of Crystal River Unit. 3 will be 2065 W..-The =argin of 204 W is insuf-ficient for maintenzace outagesi forced outages, or forecast errors.
