consistent with exception and enhancement. One was not applicable. One example is the Buried and Underground Piping and Tanks programme. The staff examined 19 enhancements to this existing programme. Several enhancements refer to additional inspection:


● An inspection method that has been demonstrated to be capable of detecting cracking when inspections of uncoated stainless steel piping are performed.


● Inspect controlled low strength material backfill for cracking that could admit groundwater to the external surface of the embedded pipe.

● Additional inspections when measured pipe wall thickness, projected to the end of the subsequent period of extended operation, does not meet the minimum pipe wall thickness requirements due to external corrosion.


● Visual inspections of buried steel piping in the fuel oil system at least once every ten years. Visual inspections of at least one ten-linear-foot section of buried stainless-steel piping in the primary and demineralised water makeup system at least once every ten years.

● Visual inspections of at least two ten-linear-foot sections of underground coated steel piping in the condensate or service water systems at least once every ten years.


● Visual inspections of at least one ten-linear- foot section of underground uncoated stainless steel piping in the auxiliary feedwater, chemical and volume control, condensate, primary and demineralised water makeup, or service water systems at least once every ten years.


● Visual inspections of the concrete encapsulated components in the north service water header.


Renewing the licence A licence renewal application must include an Updated Final Safety Analysis Report (UFSAR) with a summary description of the applicant’s programmes and activities for managing the effects of ageing. Time limited ageing analyses must be identified and updated for the period of extended operation, demonstrating that these analyses will remain valid, that the analyses have been projected to the end of the period or that the effects of ageing will be adequately managed. The requirements for licence renewal are described in 10 CFR Part 54. One section, ‘Contents of application – technical specifications’,


requires that the SLRA include any changes or additions to the technical specifications that are necessary to manage ageing effects during the period of extended operation. Duke stated that no changes to technical specifications are necessary for issuance of a subsequent renewed operating licence and the NRC staff found that this statement adequately addresses the requirements. An item is considered to be open if the NRC staff


have not determined that the item meets all applicable regulatory requirements. After reviewing the SLRA, including additional information the staff identified no open items. An item is considered confirmatory if the staff and the applicant have reached an acceptable resolution that meets all applicable regulatory requirements but, at the time of the issuance of this SE, the staff had not received the necessary documentation to confirm the resolution. After reviewing the SLRA, including additional


information, the staff found no confirmatory items exist that require a formal response from Duke. After reviewing information submitted up to 1 October 2025, the NRC staff


deemed two licence conditions appropriate: ● Following the staff’s issuance of the subsequent renewed licence, Duke has to include the UFSAR supplement (containing a summary of programmes and activities for managing the effects of ageing and an evaluation of time limited aging analyses) in its next periodic UFSAR update


● Duke is required to complete future activities described in the UFSAR supplement no later than six months before the beginning of the subsequent period of extended operation and must also notify the NRC in writing when it has completed those activities. Unless modified in accordance with 10 CFR 50.59, the programmes and commitments described in the UFSAR supplement remain in effect during the subsequent period of extended operation. ■
