LIST OF REGULATORY COMMITMENTS The following list identifies those actions committed as regulatory commitments by Dominion Energy Kewaunee (DEK) for the Kewaunee Power Station (Kewaunee). Any other actions discussed in DEKs license amendment request are not regulatory commitments.
This following list is derived from Commitment List, accessible in ADAMS by its Accession number as ML102371197.
No. Commitment Due Date/Event DEK will have written procedures available describing the compensatory measures when LCO 3.7.10, Control Room 1 Post-Accident Recirculation (CRPAR) System, ACTION Upon implementation B, Two CRPAR trains inoperable due to inoperable control room boundary in MODE 1, 2, 3, or 4, is entered.
DEK will establish the Technical Specification Bases for 2 LCO 3.0.8, as adopted, with the applicable license Upon implementation amendment.
DEK will ensure that when LCO 3.0.8a is used, appropriate plant procedures and administrative controls are revised to implement the following Tier 2 Restriction:
3
- At least one AFW train (including a minimum set of Upon implementation supporting equipment required for its successful operation) not associated with the inoperable snubber(s) must be available.
DEK will ensure that when LCO 3.0.8b is used, appropriate plant procedures and administrative controls are revised to implement the following Tier 2 Restriction:
- At least one AFW train (including a minimum set of 4 supporting equipment required for its successful Upon implementation operation) not associated with the inoperable snubber(s), or some alternative means of core cooling (e.g., F&B, firewater system or aggressive secondary cooldown using the steam generators) must be available.

LIST OF REGULATORY COMMITMENTS No. Commitment Due Date/Event DEK will ensure that when LCO 3.0.8 is used appropriate plant procedures and administrative controls are revised to implement the following Tier 2 Restriction:
- Each time the provisions of LCO 3.0.8 are used DEK will confirm that at least one train (or subsystem) of systems supported by the inoperable snubbers would 5 remain capable of performing their required safety or Upon implementation support functions for postulated design loads other than seismic loads. LCO 3.0.8 does not apply to non-seismic snubbers. In addition, a record of the design function of the inoperable snubber (i.e., seismic vs.
non-seismic), implementation of any applicable Tier 2 restrictions, and the associated plant configuration shall be available on a recoverable basis.
DEK will revise the USAR or TS Bases to describe the In accordance with 10 CFR 6
restrictions in commitments 3 and 4. 50.71(e)
DEK will have written procedures available describing compensatory measures to be taken in the event of an intentional or unintentional entry into LCO 3.7.12, Auxiliary 7 Upon implementation Building Special Ventilation (ASV) System, Condition B, Two ASV trains inoperable due to inoperable ASV boundary.
8 Withdrawn, refer to Enclosure Volume 8. N/A 2
LIST OF REGULATORY COMMITMENTS No. Commitment Due Date/Event DEK will implement administrative controls to include the following restrictions.
- Activities that could degrade the availability of the auxiliary feedwater system, reactor coolant system pressure relief (pressurizer PORVs and safety valves), AMSAC (ATWS (Anticipated Transient Without Scram) Mitigating System Actuation Circuitry), or turbine trip should not be scheduled when a RTB is out of service.
9 Upon implementation
- Activities that could degrade other components of the RPS, including master relays or slave relays and activities that cause analog channels to be unavailable should not be scheduled when a logic cabinet is unavailable.
- Activities on electrical systems that support the systems or functions listed in the first two bullets should not be scheduled when a RTB is unavailable.
DEK commits to include in the USAR a requirement to maintain a 5% design margin for the batteries describing how this design margin is required to allow the use of a 2 In accordance with 10 amp float current value that is an indication that the 10 CFR 50.71(e) battery is 95 percent charged. (Duplicated in Commitment 12 but included here for completeness.)
DEK commits to incorporating the expected/qualified life In accordance with 10 11 of the safety related batteries in the battery monitoring CFR 50.71(e) program in the USAR.
3
LIST OF REGULATORY COMMITMENTS No. Commitment Due Date/Event DEK commits to change or verify that the Kewaunee USAR describes:
- 1. The requirement to maintain a 5% design margin for the batteries describing how this design margin is required to allow the use of a 2 amp float current value as an indication that the battery is at least 95 percent charged.
- 2. The minimum established design limit for battery terminal float voltage. In accordance with 12 10 CFR 50.71(e)
- 3. The minimum established design limit for electrolyte level.
- 4. The minimum established design limit for electrolyte temperature.
- 5. The minimum requirements for the alternate means (i.e., spare battery charger) that is used to obtain an extended battery charger completion time (CT).
DEK commits to change (or verify) procedure(s) to include the measuring and test equipment manufacturers 13 Upon implementation recommended practice for instrument stabilization when measuring float current to confirm battery state of charge.
DEK commits to including vital switchgear and battery In accordance with 14 room temperature limits in the USAR. 10 CFR 50.71(e)
DEK has committed in the GL 2008-01 letter to monitor Following NRC approval of the status of the industry/NRC Technical Specification the TSTF, on a schedule 15 Task Force (TSTF) Traveler to be developed as a follow- consistent with the up to GL 2008-01. Following NRC approval of this TSTF, commitment made in the DEK will adopt applicable portions of the Traveler. response to GL 2008-01.
