The Monticello Extended Power Uprate (EPU) application was supplemented during acceptance review on May 20, May28, May 30, June 3, June 5, and June 12,2008 by References 2, 3, 4, 5, 6, and 7. In a teleconference held June 20, 2008, the NRC staff stated that the application lacks sufficient information in some areas to allow the staff to proceed with its detailed technical review. Therefore, NMC is withdrawing the referenced request for the license amendments with plans to resubmit at a later date.
The revised application may refer to information previously submitted.
Commitments made for the grid stability summary and TSTF-493 in Reference 1 and a commitment made for responses to the lnstrument and Control Branch acceptance review questions in Reference 5 will be cancelled. The content of the lnstrument and Control Branch questions will be considered for inclusion into the new extended power uprate submittal.
NMC understands that, in response to this request for withdrawal, the NRC will document the results of the staffs acceptance review, indicating the areas for which additional detail is required for acceptance. Additionally, further pre-application meetings may be scheduled to discuss the technical areas lacking sufficient information.
