Request for Additional Information Regarding Braidwood Request for Alternative (I4R-18)

By letter dated January 11, 2024 (ML24012A003), Constellation Energy Generation, LLC (CEG or the licensee) requested a proposed alternative from the minimum percentage requirements contained in the ASME Code, Table IWC-2411-1, for the second inspection period which would require examination of two components in refueling outage A1R24 (April 2024) at Braidwood Unit 1 and examination of three components in refueling outage A2R24 (October 2024) at Braidwood Unit 2.

The NRC staff has identified a potential discrepancy in Section 1.0 of the Proposed Alternative I4R-18.

Section 1 states that the affected components include Steam Generator (SG) Nozzle -to-Shell Welds and Nozzle Inside Radius Sections which is part of Examination Category C-B.

Section 1 lists Item Number C2.21 - Nozzle-to-Shell (Nozzle to Head or Nozzle to Nozzle) Weld.

However, Section 1 did not list Item Number C2.22 Nozzle Inside Radius Sections even though Section 1 indicates that Steam Generator (SG) nozzle Inside Radius Sections are included in the scope of the proposed alternative.

Provide clarification whether the proposed alternative I4R-18 includes Item Number C2.22, nozzle inside radius sections.
