s' Mr. D. B. Vassallo, Assistant Director for Light Water Reactors Division of Proj ect Management U. S. Nuclear Regulatory Commission Washington, D. C. 20535

Dear Mr. Vassallo:

Enclosed is the revised enclosure to my August 30, 1977 letter as we dis-cussed on the telephone on September 9, 1977 and September 14, 1977. The revisions are identified as Revision 1.

We regret that the error was made, but we are confident that the corrected calculations are conservative and still show that there is no safety significance.

Yours very truly, cts

Enclosure:

Safety Evaluation by Toledo Edison Company as presented at August 25, 1977 meeting with NRC (Revision 1) l t i F
