The proposed amendments would revise the technical specifications (TSs) for each facility based on Technical Specification Task Force (TSTF) traveler TSTF-541, Revision 2, Add Exceptions to Surveillance Requirements for Valves and Dampers Locked in the Actuated Position (ADAMS Accession No. ML19240A315).

make similar changes to surveillance requirements (SRs) not included in TSTF-541, Revision 2, and additional editorial changes to the TSs.

The U.S. Nuclear Regulatory Commission staff has reviewed the application and determined that the information below is needed to complete its review.

Request Additional Information (RAI) 1

The TS markups provided in the application include several changes that are not consistent with TSTF-541, Revision 2, and are not identified as variations in the application. The differences between the markup and the changes in TSTF-541, Revision 2, are as follows:

Dresden In its TS markup for SR 3.6.4.3.3, the licensee added except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position. The TSTF-541 markup does not include valves.

Fitzpatrick In its TS markup for SR 3.6.4.3.3, the licensee added except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position. The TSTF-541 markup does not include valves.

Limerick In its TS markup for SR 4.6.5.3.d.2, the licensee added except for valves that are locked, sealed, or otherwise secured in the actuated position. The TSTF -541 markup includes only dampers, not valves for this SR.

NMP-2 In its TS markup for SR 3.6.4.3.3, the licensee added except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position. The TSTF-541 markup does not include valves.

Peach Bottom In its TS markup for SR 3.6.4.3.3, the licensee added except for valves that are locked, sealed, or otherwise secured in the actuated position. The TSTF-541 markup only includes dampers, not valves.

Quad Cities In its TS markup for SR 3.6.4.3.3, the licensee added except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position. The TSTF-541 markup does not include valves.

In its TS markup for SR 3.7.4.3, the licensee added except for dampers that are locked, sealed, or otherwise secured in the actuated position. The TSTF-541 markup includes dampers and valves.

Confirm that these differences are variations from TSTF-541, Revision 2, that are necessary to reflect plant-specific configurations. Otherwise, provide an explanation for these variations from the TSTF traveler.

RAI 2

The TS markup for Limerick, Unit 2, proposes to add the following footnote to SR 4.7.3.c.1 :

Except for valves that [are] locked, sealed, or otherwise secured in the actuated position.

However, the word are is missing as indicated by the bracketed text. Provide the correct wording for this proposed footnote.
