MF5818 - Browns Ferry - Proposed Change to Browns Ferry Unit 3 Technical Specifications Concerning the Safety Limit Minimum Critical Power Ratio (SLMCPR) Acceptance Review decision Importance:
High
- Gordon, By letter dated March 6, 2015 (ML15090A436), Tennessee Valley Authority (the licensee, TVA) submitted a license amendment request (LAR) for Unit 3 of the Browns Ferry Nuclear Plant (BFN). The proposed amendment would modify the Technical Specifications (TSs) to revise values for the safety limit minimum critical power ratio (SLMCPR) based on analyses using a new methodology that was previously approved for BFN, but is being utilized for Unit 3 for the first time. BFN received NRC approval for the SLMCPR methodology update in 2014 associated with the transition core design utilizing the first batch of ATRIUM 10XM fuel (ML14108A334).
The purpose of this e-mail is to provide the results of the NRC staffs acceptance review of this amendment 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 Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the TSs) 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 NRC staff has reviewed TVAs application and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment request in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. The licensee will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.
