Callaway Plant, Unit 1 - Acceptance of Requested Licensing Action Re:

Request for One-Time License Amendment to Defer Upcoming Steam Generator Inspection (EPID L-2020-LLA-0142)[COVID-19]

Dear Mr. Elwood:

By letter dated June 26, 2020 (Agencywide Documents Access and Management System (ADAMS Accession No. ML20178A668)), supplement by letter dated July 21, 2020 (ADAMS Accession No. ML20203M327), Ameren Missouri (Union Electric Company) (the licensee) submitted a license amendment request (LAR) for Callaway Plant, Unit 1. This LAR is requesting, on an expedited basis, approval of a one-time license amendment regarding the steam generator tube inspection required per part d.2 of Callaway Technical Specification (TS) 5.5.9, Steam Generator (SG) Program. Specifically, approval of a change to the TS is requested to allow the SG tube inspection (eddy current testing), currently scheduled to be performed during Refuel Outage (RFO) 24 this coming October (2020), to be deferred such that it would instead be performed during RFO 25, which is scheduled for the spring of 2022. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this LAR. 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 application for an amendment to a license (including the technical specifications) [or construction permit] 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 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. If additional information is needed, you will be advised by separate correspondence.

Based on the information provided in your submittal and discussions during the pre-licensing meeting held on June 24, 2020 [meeting summary (ADAMS Accession No. ML20189A199)], the NRC staff has estimated that this licensing request will take approximately 300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br /> to complete. The NRC staff expects to complete this review in approximately 4 months, which is

October 2020. 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. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.

If you have any questions, please contact me.

Sincerely, Mahesh Chawla, Project Manager Licensing Branch, LPL4 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Phone: (301) 415-8371 Email: Mahesh.Chawla@nrc.gov
