'me use of 8x8 fuel in tuloads has been reviewed cn a ginaric basis by the Licensing staff and the Advisory Otxmittee on Reactor Safegturds (ICS) . '1he reports based cn thcos revicus were transmitted to you lyf letters dated February 11 and 20, 1974. 'Ihe staff Safety Dealuation for

Based on these revicws and the analysis of abnnma_1 core transicnts and the effects of fuel deruification consiocrea in the i.nclosed Safety rNaltution, we haw concitrbd that tne health and safety of the public will not be Wad by operaticn of the ItnHmilo faH11ty with the 8x8 ftel and with the associated prrr=_M changes to the 'nxinical Spomficaticns.

'Iho above hamt No. 3 to License No. IFR-22 with 01ange No.14 to the Tedulical Spacifir-aticos also inniwh most of the chances you rogmsted January 23, 1974, and thrdt 1, L974, as stpplemnted by yotn-filings dated Ihren 8 and 19 and April 10 and 26,1974, relating to pressure relief, c21 trol rod scrau Hnw, Standby gas treatment systm '

and reactor vessel tmporature measummits. A disemsion of those changes and our findings related thereto, and a disemsicn of those ~

itsa not approved follcus.

By letter dated April 10, 1974, you regtestod changes to tna 'Ibcnnical Spncifications to allow oraration of fini ejcle 3 without dopmcence on the prapt relief trip systm (PRr) or reauction in on1culational mnservatis::U. Our revicw of the PRI system prcposed by your letter dated January 23, 1974, is in progrms. At this tine we have not detnrmined that the PRT systrm can be marn operational without affectirx; the existing engineered safety systzx:n or the reactor protection syntan. ,

licrording to your April 10, 1974 prnevel and the analytical results tnat were inn 1wM, core design and plant safety margins are acmqtuto to permit normal plant operations for 4200 fwd /T fml depletirn uuring fml cycle 3. 'Lhmnfter a ;xucr reducticn would be newf unless the PRr systIra has been aW. and pinrM in servim. Approval of the PRr will require amend::ent of the licenso for the obnticello nuclear Facilit/.

i We nave revicwed your @ril 10, 1974 reanalysis for operaticn with fwl cycle 3 without the PRI system and the tecnnical specification chances that you have selected fmn earlier suhtcittals dated February 27, 28 ana j tiardt 1,1974, when it was anticipated that the PRI system would be approwd for the initial reactor operation during cycle 3. de have ococitrud that l

l with four new safety relief valves installed in plam of the four spring-lanced safety valws that nave been rmowd (in addition to tin four initially installcd safety relief valves), there are no significant safeef l ccnsiderations and safety margins during the first 4200 mcVT of cycle 3 ftel exposure and, thercafter as long as 1GFRs are greater than tho l

tectmical specification linit of 1, are accaptable. Because we inw l not cmpleted our evaluation of utr l analytical nethocs and in accorcance i sith telgrcno conversations with your representatives, we have clanged

tne tac!1nical specifications to requiru that a minirun of sewn safety /

relief valves to operative uuring reactcr cperation insteaa of tne six tnat you had proposed. 'ihe reason for titis chanau is that seven safety /

ralinf valves set at a narinal trip pressure of 1980 psig provide a

! total steam relief ficw capacity cauivalent to the four safety / relief i valves and four spring 1movt safety valws that vero instm1N prior to tne spring 1974 plant outago. Ln an interi2n basis or until we have cmpletco our evaluaticrs related to your calculational rethocs, to gevent overstrcesing in the prrary system, the relief capacity emnl to or j quaa mi1 3 i m ei m rie % w 949muius q. l l
