Subject:
Palo Verde 1, 2, and 3 - Acceptance Review for an Exemption Regarding Elimination of DAFAS Using RIPE Process (EPID L-2022-LLE-0004)
By letter dated January 14, 2022 (Agencywide Documents Access and Management System Accession No. ML22014A415), Arizona Public Service Company (APS, the licensee) submitted an exemption to delete Diverse Auxiliary Feedwater Actuation System (DAFAS) using Risk-Informed Process for Evaluations (RIPE) for Palo Verde Nuclear Generating Station, Units 1, 2, and 3 (Palo Verde). Specifically, the proposed change is a request from APS for an exemption under Title 10 of the Code of Federal Regulations (10 CFR) Section 50.12, Specific Exemptions, from certain requirements in 10 CFR 50.62, Requirements for reduction of risk from anticipated transients without scram (ATWS) events for light-water-cooled nuclear power plants, for Palo Verde.
The licensees request is for partial exemption from 10 CFR 50.62(c)(1). The portion of 10 CFR 50.62(c)(1) for which the exemption is requested is shown below in bold.
(c) Requirements. (1) Each pressurized water reactor must have equipment from sensor output to final actuation device, that is diverse from the reactor trip system, to automatically initiate the auxiliary (or emergency) feedwater system and initiate a turbine trip under conditions indicative of an ATWS. This equipment must be designed to perform its function in a reliable manner and be independent (from sensor output to the final actuation device) from the existing reactor trip system.
The requirements for Palo Verde is to provide a Diverse Scram System (DSS), DAFAS and Diverse Turbine Trip (DTT). The exemption request will remove the requirement for the DAFAS from the Palo Verde licensing basis based on the RIPE. This exemption does not alter the requirements for the DSS or DTT at Palo Verde.
The purpose of this e-mail is to provide the results of the U,S Nuclear Regulatory Commission (NRC) staffs acceptance review for the above Palo Verde exemption. 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.
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 exemption 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 this licensing request will take approximately 93 hours0.00108 days <br />0.0258 hours <br />1.537698e-4 weeks <br />3.53865e-5 months <br /> to complete. The NRC staff expects to complete this review approximately by April 18, 2022, or earlier. 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 request for confirmation of information, or unanticipated addition of scope to the review.
If you have any questions, please contact me at (301) 415-1564.
