The Monticello BWR Pilot Plant Life Extension Program was initiated in 1985 to examine in some detail the technical and economic viability of life extension for an operating nuclear power plant. The scope of the Phase 1 study was the identification, importance ranking and life assessment of the critical plant components. Results of this initial phase were reported in EPRI Report NP-5181 and provided the basic encouragement to embark on a generic effort and formulation of the Nuclear Utility Plant Life Extension Program (NUPLEX). The Phase 1 conclusions, based on the initial 27 critical component assessments, contained a number of qualifiers and assumptions with respect to the remaining plant components. To verify the earlier assumptions and to expand the technical bases for a planned future license renewal process, the scope of the Phase 2 program was chosen to include evaluation of essentially all remaining plant components and structures and to supplement the technical assessments with in-plant inspections and component condition assessments. In the course of the Phase 2 assessments, the maintenance aspect of life extension was evaluated and a comprehensive listing was developed of anticipated or recommended life extension activities. Even though the evaluations were limited to the Monticello unique components and operating history, the plant is substantially generic and representative of many other operating BWR's, such that a significant value can be derived in the planning phase for other similar plants wishing to commence with longer term preparation for license renewal. 2 refs., 15 figs., 36 tabs.
