Description of Site and Environment and safety requirements. Certain activities can be performed while the reactor is operating, while others require that the facility be shut down. Long-term outages are scheduled for refueling and for certain types of repairs or maintenance, such as replacement of a major component. NMC refuels Monticello on a nominal 22- to 24-month fuel cycle. During refueling outages, site employment increases by as many as 600 workers for temporary duty (NMC 2005a). The updated safety analysis report (USAR) (NMC 2005b) regarding the effects of aging on systems, structures, and components was included as part of the Monticello application for renewal of its operating license (OL), in accordance with 10 CFR Part 54. Appendix A of the application includes a supplement to the facility USAR that describes the programs and activities that will manage the effects of aging during the license renewal period. NMC expects to conduct activities related to the management of aging effects during normal plant operation, or refueling and other outages, but plans no outages specifically for the purpose of refurbishment. NMC does not plan to add additional full-time staff (non-outage workers) at Monticello during the period of the renewed license. 2.1.7 Power Transmission System The transmission corridors of concern for license renewal are the corridors that were constructed for the specific purpose of connecting the plant to the electrical grid. Thus, for this license renewal, the transmission lines subject to review are the Monticello-Coon Creek 345-kV line and the Monticello-Parkers Lake 345-kV line (see Figure 2-5 and Table 2-1). The Monticello-Coon Creek 345-kV line (Line #0991) exits the substation to the northeast and continues 5.9 mi northwest to the Sherburne County Substation on a 240-ft wide easement (the Sherburne County corridor). It then extends 37.2 mi to the southeast to connect to the Coon Creek Substation on an easement that varies in width from 125 ft to 150 ft (Xcel Energy 2005a). The original Monticello to Coon Creek Line was modified in 1975 to connect the Sherburne County Generating Plant to the 345-kV system. The NRC addressed the configuration of the Monticello to Coon Creek Substation line in its environmental review for the initial Monticello operating license application. The Monticello-Parkers Lake 345-kV line (Line #0978) exits the substation to the southeast on a 240-ft wide easement for approximately 23.8 mi and then continues approximately 13.3 mi on a 165-ft-wide easement to the Parkers Lake Substation (Xcel Energy 2005a). The line was originally constructed to connect Monticello directly to Parkers Lake and was energized in 1971. The NRC also addressed the line's impacts in its environmental review for the initial Monticello operating license application. The Elm Creek Substation was installed on the Monticello- Parkers Lake line in 1996 (NMC 2005a). NUREG-1437, Supplement 26 2-12 August 2006 1
