Prairie Island Nuclear Generating Plant, Units 1 and 2 - Relief request to extend reactor vessel closure head component inspection frequency (EPID: L-2018-LLR-0023)

Mr. Loeffler, By letter dated March 6, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18065A583), Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, submitted a relief request for Prairie Island Nuclear Generating Plant, Units 1 and 2 to permit an alternative to the frequency specified for performance of volumetric/surface examinations of Reactor Vessel Closure Head components in the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Code Case N-729-4. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this relief request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Pursuant to Sections 50.55a(z)(1) and 50.55a(z)(2) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety.

Based on the information provided in your submittal the NRC staff has estimated that this licensing request will take approximately 120 hours5 days <br />0.714 weeks <br />0.164 months <br /> to complete. The NRC staff expects to complete this review in approximately 12 months, which is March 2019. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager.

These estimates are based on the NRC staffs initial review of the application and they could change, due to several factors including requests for additional information, unanticipated addition of scope to the review, and review by NRC advisory committees or hearing-related activities.

If you have any questions, please contact me.
