US Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555 MONTICELLO NUCLEAR GENERATING PLANT Docket No. 50-263 License No. DPR-22 Treatment of Commitments as License Conditions (TAC No. 97781)

Ref. Letter from W.J. Hill, NSP, to NRC, dated July 16,1997, " Response to Request for AdditionalInformation Regarding Revision 2 to MNGP License Amendment Dated January 23,1997 (TAC No. 97781)"

By letter dated July 16,1997, NSP made seven commitments in regard to actions associated with implementation of a license amendment request. By telephone conversation between the Monticello NRC Project Manager and Joel Beres, Monticello Licensing Engineer, NSP was notified of the Staffs intent to include these commitments as conditions of the MNGP cperating license. NSP hereby concurs with the Staffs treatment of these commitmente.

These conditions, as agreed to by NSP, are summarized below.

Prior to startup from the current maintenance outage, NSP will revise the emergency operating procedures (EOPs) to require manualisolation of torus and drywell sprays prior to the point where primary containment pressure would not provide adequate NPSH for the ECCS pumps, change the caution statement regarding NPSH in the Primary Containment Pressure EOP to include the core spray pumps, and cdd a caution statement regarding NPSH considerations for pressure control while venting to control primary containment pressure.

P-ior to startup from the current maintenance outage, NSP will finalize the additional containment analysis which extends the existing long-term case evaluation to the time when the required containment overpressure returns to atmospheric conditions. Changes to the ,

requested long-term containment overpressure, if any, will be promptly reported to the Staff prior to startup. I

)/ .

Within 90 days of startup from the current maintenance outage, NSP will submit a revision or supplement to Exhibits D and E of the license amendment request dated June 19,1997 to include the results of the containment analysis associated with the long-term case extension above.

Within 90 days of plant startup from the currer't maintenance outage, NSP willincorporate relevant portions of the Staff's SER regarding containment overpressure into Section 5 2 of the MNGP USAR. The revised Section 5.2 willinclude the approved containment overpressure and the resrective time periods.

Within 180 days of plant startup from the current maintenance outage, NSP will process a 10 CFR 50.59 evaluation to change the EOP definition of adequate core cooling to 2/3 core height. The corresponding EOP changes and the required operator training will also be completed in this time period. Final implementation will be completed when all of the 10 CFR 50.59 evaluation requirements are satisfied.

Please contact Joel Beres, Licensing Engineer, at (612) 2951436 if you require further information.
