Description of Proposed Action M
Dy letters dated July 9,1975 and August 4,1975, Northern States Power Co m ny suloittn' nroposed changer to the Tcchiical Spccii n cations Appendi: A to License Di M 2.
The proposed changes resulted frc 1: ' a^piication ef tire Accepttnce Criteria for Ercrgency Corc Coalinc Susten ('JCCS) in conjunction uito core changeout nu% er 5 and rcfueling with 8 x 8 fuel, i,orthern St' tes Pcner Ctr any is presently liccased to cperate F.cnticellc, U iit 1, located in tSc State of Minnesote, '.!rit ;t County, at pm.er levels up to 1670 r.;egawatt thermal (Mut).
Tne proposed change to incorporate the ECCS Acceptance Criteria in conjunction with the core reload will not result in any change in authorized full power level of the unit. Although restrictions on heat generation rates night require car eful control of fuel opecatir; history, there shoulc be no reduction of tctal burau;'
resulting frora application of the revised ECCS evaluation roethocs.

Envirormntal Irapacts of Proposed Action Potentici environmntal impects associated with the propored actica are those which nient be associated with incorporation of the ECCS Acceptance Criteria and utilization of new nuclear fuel for this facility.
It is particularly noted that, in the absence of any significant change in power levels, there will be no change in cooling water require ients anc consequently no increase in environmental irapact f rea rac'ioactive effluis ai.c thenral effluents for normal operating or post-accident conditions, which in turn could not lead to significant increases in radiation d ses or thennal stress to the public 'r to biota in the environment.

. For normal operating conditior,, no environmental impact other than as described in the Coast.ission's Final Environmental State-ment (FES) for tionticello, Unit 1, Docket I o. 50-263, dated November 1972, can be predicted for the proposed action. The Co:rraission's calculated releases oi radioactive effluents, both gaseous and liquid, are based on expected release rates to the environment and are quantified on the tasis of the total quantity of nuclear fuel within the reactor. The estimates of radionuclides and release rates will not be affected by the proposed action, cnd since the total quantity of nuclear fuel is unchanged, no increase in the calculated release of radioactive effluents is predicted.
Consequently, no increases in radiation doses to man or other biota are predicted.

Conclusion and De sis for liqq,tjy D:claration On th'e basis of the foregoing analysis, it is concluded that there will be no environmental impact attributable to the proposed action other than that already predictcd and described in the Conmission's FES for 14anticelle I;uclear Generating Plant, Unit 1.
