, RE: Quad-Cities. Units Nos.1 & 2 Gentlemen:

.. 'Ibe Cortmission's Regulatory Staff has conpleted a myiew of fuel densification and its effect on mactor operation including transients and postulated loss-of-coolant accidents. 'Ihe Staff's investigations

~

and conclusions am mported in "'Dechnical Report en Densification of Light Water Beactor Fuels" dated November 14,1972, a oopy of tich is-enclosed for your infomation and guidanoe. 'Ihis mport ecnoludes that densification of fuel may occur and that the asulting-formation of fuel colunn gaps should be anticipated in all light water mactor fuels. 'Ihe mport also provides the essential elements to be included in calcula-tional nodels used to account fbr the effects of fuel densification.

'Ibe Begulatory Staff believes that the fuel dn the . subject facility (s) is susceptible to densificaticn. 'Ibemfozy,, we aquest that you pro-vide the necessary analysea and other relevant data for &temining the l consequences of densification and the eUects cn nomal operation, anti-cipated transients, and accidents, dncluding the pcetulated loss-of-coolant accident, using the guidance provided in the enclosed sport.. ,

'Ibese analyses should be provided for your pmsent fuel loading. Ii"the i analyses indicate that changes in design or operating conditions am necessary to maintain mquimd margins, you should submit proposed changes and operating limitations with the analyses.

. . In order that th6 Begulatory Staff can conduct an egeditious and ozderly myiew of these matters, we aquest that you submit the analysos and
