Docket No. 50-346 Novemoer 20, 1972 The Toledo Edison Company ATTN:
Mr. Glenn J. Sampson Vice President, Power 300 Edison Plaza Toledo, Ohio 43652 RE:
Davis-Besse Nuclear Power Station Gentlemen:
The Commission's Regulatory Staf f has completed a review of fuel densification and its effect on reactor operation including transients and postulated loss-of-coolant accidents. The Staff's investigations and conclusions are reported in " Technical Report on Densification of Light Water aeactor Fuels" dated November 14, 1972, a copy of which is enclosed for your information and guidance. This report concludes that densification of fuel may occur and that the resulting formation of fuel column gaps should be anticipated in all light water reactor fuels. The report also provides the essential elements to be included in calculational models used to account for the effects of fuel densi-fication.
The Regulatory Staf f believes that the fuel for the subject facility (s )
is susceptible to densification. Therefore, we request that you provide the necessary analyses and other relevant data for determining the conse-quences of densification and the effects en normal operation, anticipated transients, and accidents, including the postulated loss-of-coolant accident, using the guidance provided in the enclosed report. If tne analyses indicate that changes in design or operating conditions are necessary to maintain required margins, you should submit proposed
~
changes and operating limitations with the analyses.

s 2-In order that the Regulatory Staff can conduct an ' expeditious and orderly review of these matters, we request that you submit the analyses and additional information within 45 days from the date of this letter.

If your submittal is for more than one unit, a total of sixty copies is needed.
Sincerely,
