Final Review Review Status: Not Cc alete Our me-rrandum of July 3,1973 identified several areas of tae Davis-lesse rsaa.<nich were incomolete to the extent t,at our first-Reuno Technical deviev Schedule was affected. Aronn thes2 areas was the absence ia t1e FSAR of LOCA analyses.
At that time,.de incicated tnat cor.712 tion of Firn-Mcund Questions must t9erefore be delayed until the applicant had sucmitted
- he ruterial.
Amndrent 15, recer.tly suMitted on t,e Javis-Gesse dcchet, provides a nu:cer of FSAR Revisiens in the areas of LOCA analysis and ECCS desi.n..'.!e have 2xamined tais raterial and the attacned li':t orovides the required additional inferraticq vaien we are able to identify at tais ti.Te.
- le 7 ave noted your letter to J. !!. Hendrie, dated 'Jctober 13, 1973, in which you indicated that ilthougn the Davis-Besse facility cemletion las slip?cd, it may se crucent to revie.1 i: mediately r aterial such as Amnd:mnt 16 tc avoid cackloccing tiesa i t cs. Hrvever, tha LOCA analysis is act comicte. The applicant nas providad an analyses of one large break in Amend:r,ent 16, in accordacc? vith oresant ECCS performnce critoria, sn.1 indicates that nther larce break analyses siil 5e pro-vided to tne revised AEC Acceptance Criteria at a later date. We accept tais position and we further note tnat certain portions of tne analyses oresented for Davis-3 esse are inconsistent wita r2ferenced SW topical reports or otS2r 3W SAR's.
Therefore, the LOCA analysis is an ooen iter on the docket whien must be civen First-Round review af.ter receipt of analyses in accordance with tne ney ECCS rule. Should the new ruldA5e published wit 5fn the near future, then a complete ECCS analysis usino the current Interim Acceptance Critaria vill be required. ' dita regard to srall pipe bronks, for the second time the toolic?nt has delayed submittal of these analyses. Again, we will not be able to comleta our First-;1ound Questicns without this caterial.
