Inaccordance with the requirements of 10 CFR 54.21, measures are described in this application which provide assurance that the effects of aging will be adequately managed, consistent with the current licensing basis, for the requested period of extended operation. In some cases, new aging management programs or enhancements to existing programs are described.

In some cases, new aging management programs or enhancements to existing programs are described.
During the performance of the environmental review, no new and significant information was identified that would either invalidate NRC Category 1 findings in NUREG-1437 or identify any new issues requiring evaluation. A review of the applicable Category 2 issues determined that the impacts of MNGP license renewal will be small.

NM C Monticello Nuclear Generating Plant Committed to Nuclear ExceIl enc Operated by Nuclear Management Company, LLC March 16, 2005 L-MT-05-014 10 CFR Part 54 US Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 Monticello Nuclear Generating Plant Docket 50-263 License No. DPR-22 Application for Renewed Operating License Pursuant to U. S. Nuclear Regulatory Commission (NRC) regulations 10 CFR Parts 50, 51, and 54, Nuclear Management Company, LLC (NMC) hereby applies for renewal of the Operating License for the Monticello Nuclear Generating Plant (MNGP).

The current operating license for the Monticello plant expires at midnight, September 8, 2010. NMC requests that the MNGP Operating License be extended for 20 years beyond the current expiration date to midnight, September 8, 2030.

The enclosed 'Application for Renewed Operating License, March 2005" is submitted in accordance with the applicable requirements of 10 CFR Part 54, Sections 54.17, 54.19, 54.21, 54.22, and 54.23. This application meets the timeliness requirements of 10 CFR 2.109(b) and 10 CFR 54.17(c) and provides the administrative, technical, and environmental information sufficient to support the NRC findings required by 10 CFR 54.29.

In accordance with the requirements of 10 CFR 54.21, measures are described in this application which provide assurance that the effects of aging will be adequately managed, consistent with the current licensing basis, for the requested period of extended operation. In some cases, new aging management programs or enhancements to existing programs are described.

During the performance of the environmental review, no new and significant information was identified that would either invalidate NRC Category 1 findings in NUREG-1437 or identify any new issues requiring evaluation. A review of the applicable Category 2 issues determined that the impacts of MNGP license renewal will be small.
