' Docket Nos. 50-313 November 20, 1972 and 50-368 Arkansas Power and Light Company ATTN: Mr. J. D. Phillips Vice President &
Chief Engineer Sixth and Pine Streets Pine Bluff, Arkansas 71601 RE: Arkansas Nuclear One - Units 1 and 2 Centlemen:
The Commission's Regulatory Staff 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 Reactor 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 Staff 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 on normal operation, anticipated transients, and accidents, including the postulated loss-of-coolant accident, using the guidance provided in the enclosed report. If the 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.

Sincerely, A. Giambusso, Deputy Director for Reactor Projects Directorate of Licensing
