Dear Vr. Ziemann:

M*)8' f.DilTICELLO IJELEAR GEtERAlliti PL AfJT Docket tb. 50-263 Li cence ib. DPR-22 Pequest for Supplemental Information on Technical Speci fication Change Reg;est Dated September 1,1972 Your letter of December 21, 1972, requested supplemental informat ion wi thin 33 days on the f.bnticello Technical Speci fication Change Requect dated Septomber 1,1972 (Supplement Ib.1 to Chance Reques t tb. 3).

The portion of the Cham e Recpest dealing with the rod drop accident analysic was based on General Electric topical report TED010527.

We have determined that General Electric will iccue another topical report on this subject in early February.

Uce of this report will enable uc to provide information which is more responsive to your request.

particularly for the core as constituted subsequent to our flarch-Apri;, 1973 refuelinf outare.

'hu W i th the e xi s t i ng '.b nt i cel l o co re, current plant operating conditions and our present operating practices, the consequences of the unlikely rod drop accident would be significantly loss severe than those analyzed in the referenced topical

" ^ "

report and in the '/enticello FSAR.

Based on the above information, we believa that a timo extension for our reply is appropriate.

This was discussed by telephone with your organi:stion and was deemed acceptable.

No expect to have our response completed by March 1,1973.

7 Yours very truly, D.
