LIC-109 Acceptance of Duane Arnold Energy Center LAR (TSCR-169) - Revision to Technical Specification Table 3.3.2.1-1, "Control Block Instrumentation" - CAC No. MF9494

Dear Mr. Davis:

By letter dated March 24, 2017 (ADAMS Accession No. ML17086A442), NextEra Energy Duane Arnold, LLC (NextEra)(the licensee) submitted a license amendment request for Duane Arnold Energy Center (DAEC). The proposed amendment request would revise DAEC Technical Specifications (TS) Table 3.3.2.1-1, "Control Rod Block Instrumentation." The proposed change would relocate cycle specific Minimum Critical Power Ratio (MCPR) values to the DAEC Core Operating Limits Report (COLR). The purpose of this email is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's 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 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 NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete 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 staff's ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that this licensing request will take approximately 280 hours0.00324 days <br />0.0778 hours <br />4.62963e-4 weeks <br />1.0654e-4 months <br /> to complete. The NRC staff expects to complete this review in approximately 12 months, which is March 31, 2018. 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 staff's 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. Thanks Mahesh Chawla Project Manager Phone: 301-415-8371 2Fax: 301-415-1222 mahesh.chawla@nrc.gov
