Prairie Island Nuclear Generating Plant, Units 1 and 2 - Acceptance Review for LAR Supporting SFP Criticality TS Changes (CAC Nos. MF7121 and MF7122)

Dear Mr. Adams:

By letter to the U.S. Nuclear Regulatory Commission (NRC) dated November 17, 2015 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML15327A244), Northern States Power Company - Minnesota (the licensee), doing business as Xcel Energy, Inc., submitted a license amendment request (LAR) for the Prairie Island Nuclear Generating Plant (PINGP), Units 1 and 2. The licensee proposes to revise PINGP Technical Specification (TS) 3.7.16, "Spent Fuel Storage Pool Boron Concentration," and TS 4.3.1, "Fuel Storage Criticality," to allow spent fuel pool storage of nuclear fuel containing a boron-based neutron absorber in the form of zirconium diboride IFBA [integral fuel burnable absorber]. The proposed change involves an explicit change to the criticality analysis methodology, and also introduces two changes to the licensing basis as inputs to the models used in the spent fuel criticality analysis.

Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the technical specifications) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations. The purpose of this e-mail is to provide the final results of the NRC staff's acceptance review of this 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 and make an independent assessment regarding the acceptability of the proposed change. 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. The NRC staff has reviewed your application and concluded that there appears to be sufficient technical information, both in scope and depth, to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the LAR in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised by separate correspondence. Should you have any questions regarding this review, please contact Rob Kuntz at (301) 415-3733.
