Subject:
Millstone Power Station, Unit No. 3 - Acceptance Review Determination for Alternative Request for Extension of Examination Interval for Reactor Pressure Vessel Head Penetration Nozzles (EPID L-2022-LLR-0067)
Date: Tuesday, October 25, 2022 1:37:52 PM
- Shayan, By letter dated September 28, 2022 (ADAMS Accession No. ML22271A913), Dominion Energy Nuclear Connecticut, Inc. (the licensee) submitted Alternative Request IR-4-11 pursuant to Title 10 of the Code of Federal Regulation (10 CFR) Section 50.55(z)(2) for the extension of the examination interval for the Millstone Power Station, Unit 3 (MPS3) reactor pressure vessel head penetration nozzles (RPVHPNs) that have undergone the ultra high pressure cavitation peening process. Specifically, the licensee proposes to extend the MPS3 RPVHPN follow-up volumetric examination from the second refueling outage (RFO) after peening (i.e., in fall 2023), to the third RFO after peening (i.e., in spring 2025).
The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this proposed licensing action. 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 10 CFR, whenever a holder of an operating license under this part desires to amend the license, application for an amendment must be filed with the Commission fully describing 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, the NRC staff has estimated that this licensing request will take approximately 120 hours0.00139 days <br />0.0333 hours <br />1.984127e-4 weeks <br />4.566e-5 months <br /> to complete. The NRC staff expects to complete this review by October 25, 2023. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date (greater than a month) or significant changes in the forecasted hours (greater than 25%),
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 and unanticipated addition of scope to the review. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.
Please contact me if you have any questions. A copy of this email will be made publicly available in ADAMS.
