1 REQUEST FOR CONFIRMATORY INFORMATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SEQUOYAH 1&2 - REVISE FHA ANALYSIS, DELETE TS 3.9.4 AND TO MODIFY TS 3.3.6 LAR to TENNESSEE VALLEY AUTHORITY SEQUOYAH, UNITS 1, 2 DOCKET NO. 05000327, 05000328 EPID L-2024-LLA-0117 ISSUE DATE: 12/12/2024

Background

By letter dated August 28, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24247A185), the Tennessee Valley Authority submitted a license amendment request to the U.S. Nuclear Regulatory Commission. The request is to revise the Fuel Handling Accident Analysis, to delete Technical Specification 3.9.4, and to modify Technical Specification 3.3.6 for Sequoyah Nuclear Plant, Unit 1 and 2.

Question 1 RG 1.183, Revision 0, Footnote 11 states that the non-LOCA gap release fractions in Table 3 of RG 1.183 Rev. 0 are acceptable for fuel with a peak rod-average burnup up to 62 GWd/MTU, provided the maximum linear heat generation rate does not exceed 6.3 kW/ft peak rod average power for burnups exceeding 54 GWd/MTU.

Table 3.1.1-1 of Enclosure 1 of the license amendment request indicates that the RG 1.183 Rev.

0 non-LOCA gap release fractions are used in the updated fuel handling accident dose analysis, but does not clarify that the Footnote 11 range of applicability is met. Please confirm that the RG 1.183 Rev. 0 Footnote 11 burnup and linear heat generation rate range of applicability will be met.
