By letter dated June 19, 2023 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML23170A015), Duke Energy Carolinas, LLC, (the licensee, Duke Energy) submitted a license amendment request (LAR) for Catawba Nuclear Station, Units 1 and 2. The proposed change would revise Catawba Technical Specification (TS) 3.7.11, Control Room Area Chilled Water System (CRACWS), to modify the TS Actions for two inoperable CRACWS trains.
The NRC staff has reviewed the application and determined that additional information is needed to complete the review. Please respond within 30 days of the date of this e-mail.
Please note that the NRC staffs review is continuing and further requests for information may be developed.
As described in LIC-115, Revision 1, Processing Requests for Additional Information (ML21141A238), NRC staff requests the following requests for confirmation of information (RCI).
RCI No. 1 Section 2.4 of the LAR states:
A new Condition E is added. The new Condition E states, Required Action and associated Completion Time of Condition E not met in MODE 1, 2, 3, or 4.
The TS markup page states:
Required Action and associated Completion Time of Condition D not met in MODE 1, 2, 3, or 4.
The TS markup page appears to be correct. Please confirm the apparent editorial error in LAR Section 2.4.
Duke Energy Response to RCI No. 1 Duke Energy hereby confirms the editorial error in Section 2.4 of the LAR. The TS markup page from Attachment 1 of the LAR dated June 19, 2023 is correct. Section 2.4 of the LAR should have stated, Required Action and associated Completion Time of Condition D not met in MODE 1, 2, 3, or 4.
