Acceptance Review Determination - Millstone Unit 3 - Proposed Alternative Request P-06 for "C" Charging Pump Test (EPID: L-2018-LLR-0078)

Wanda, By letter dated May 29, 2018 (ADAMS Accession No. ML18156A131), Dominion Energy Nuclear Connecticut, Inc. (DENC) requested an alternative to the requirements of the American Society of Mechanical Engineers Code for Operation and Maintenance of Nuclear Power Plants 2012 Edition, ISTB-3400, "Frequency of lnservice Tests," for Millstone Power Station, Unit 3 (MPS3) for the 'C' charging pump (3CHS*P3C).

The purpose of this e-mail is to provide the results of the Nuclear Regulatory Commission (NRC) staffs acceptance review of this relief 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 submittal 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 DENCs submittal and concludes 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. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that the review of the relief requests will take approximately 150 hours6.25 days <br />0.893 weeks <br />0.205 months <br /> to complete. The NRC staff expects to complete this review by March 2019 (i.e., approximately 9 months). 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.

Thanks,
