Final SE Associated for EPRI Technical Report 3002018337 _Use of DVR Methods for MUR.pdf Mr. Kurtis Crytzer, Program Manager Electric Power Research Institute 1300 West W.T. Harris Boulevard Charlotte, NC 28262

Dear Mr. Crytzer,

By letter dated January27,2021 (Agencywide Documents Access and Management System (ADAMS) Accession No.ML21053A027), Electric Power Research Institute (EPRI) submitted EPRI Report 3002018337, "Use of Data Validation and Reconciliation Methods for Measurement Uncertainty Recapture: Topical Report, to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. EPRI Report 3002018337, November 2020, presents a process for using a mathematical Data Validation and Reconciliation (DVR) method for monitoring core thermal power and use of the methods for Measurement Uncertainty Recapture (MUR) Uprates.

By email dated May6,2023, the NRC staff issued its draft safety evaluation (SE) (ADAMS Accession No.ML23088A184) for proprietary review.

By letter dated June15,2023 (ADAMS Accession No.ML23170A020), EPRI informed the NRC staff that there was no proprietary information in the draft SE.

The NRC staff has found that there is reasonable assurance that the DVR method as described in EPRI TR3002018337 can be used to determine the core thermal power and the core thermal power uncertainty, provided all DVR conditions and limitations have been satisfied. The final SE defines the basis for our acceptance of the TR.

Our acceptance applies only to material provided in the subject TR. We do not intend to repeat our review of the acceptable material described in the TR. When the TR appears as a reference in license applications, our review will ensure that the material presented applies to the specific plant involved. License amendment requests that deviate from this TR will be subject to a plant-specific review in accordance with applicable review standards.

In accordance with the guidance provided on the NRC website, we request that EPRI publish an accepted version of TR3002018337, within three months of receipt of this email. The approved versions shall incorporate this letter and the enclosed final SE after the title page.

The accepted version shall include an A (designating accepted) following the TR identification symbol.

If future changes to the NRCs regulatory requirements affect the acceptability of this TR, EPRI will be expected to revise the TR appropriately. Licensees referencing this TR would be expected to justify its continued applicability or evaluate their plant using the revised TR.

If you have any questions or require any additional information, please feel free to contact the
