Serial No.09-491 ATTACHMENT 5 LICENSE AMENDMENT REQUEST 249 KEWAUNEE POWER STATION CONVERSION TO IMPROVED TECHNICAL SPECIFICATIONS COMMITMENT LIST KEWAUNEE POWER STATION DOMINION ENERGY KEWAUNEE, INC.
Serial No.09-491 Docket No. 50-305 Attachment 5 Page 1 of 3 COMMITMENT LIST The following list identifies those actions committed to by Dominion Energy Kewaunee (DEK) for the Kewaunee Power Station (Kewaunee) in this document. Any other actions discussed in the submittal represent intended or planned actions; they are described only for information and are not regulatory commitments. Please contact Mr.
Gerald O. Riste - ITS Conversion, Licensing, at (920) 388-8424 for any questions regarding this document or any associated regulatory commitments.
No. Commitment Due Date/Event DEK will have written procedures available describing the compensatory measures when LCO 3.7.10, Control Room Post-Accident Recirculation 1 Upon Implementation (CRPAR) System, ACTION 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 2 Bases for LCO 3.0.8, as adopted, with the Upon Implementation applicable license 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 Upon Implementation minimum set of 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 supporting equipment 4 required for its successful operation) not Upon Implementation 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.
Serial No.09-491 Docket No. 50-305 Attachment 5 Page 2 of 3 COMMITMENT LIST 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:
- Every 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 remain capable 5 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 restrictions in commitments 3 and 4. In Accordance with 6
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 Building Special 7 Ventilation (ASV) System, Condition B, Two ASV Upon Implementation trains inoperable due to inoperable ASV boundary.
DEK will add procedural direction to perform an extent of condition evaluation and perform additional testing for plausible common failure 8 modes associated with RPS and ESFAS Upon Implementation instrument analog channels.
Serial No.09-491 Docket No. 50-305 Attachment 5 Page 3 of 3 COMMITMENT LIST No. Commitment Due Date/Event DEK will implement administrative controls to include the above 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
- Activities that could degrade other Upon Implementation 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.
