KEWAUNEE POWER STATION LICENSE AMENDMENT REQUEST 244: PROPOSED REVISION TO RADIOLOGICAL ACCIDENT ANALYSIS AND CONTROL ROOM ENVELOPE HABITABILITY TECHNICAL SPECIFICATIONS By letter dated July 25, 2011 (ML11222A123), Dominion Energy Kewaunee, Inc. (DEK) requested an amendment to Facility Operating License Number DPR-43 for Kewaunee Power Station (KPS).
This proposed amendment would revise the KPS Operating License by modifying the Technical Specifications (TS) and the current licensing basis (CLB) to incorporate changes to the current radiological accident analysis (RAA) of record. This proposed amendment would revise the current RAA for the design-basis accidents (DBAs) described in Chapter 14 of the KPS Updated Safety Analysis Report (USAR).
This amendment would also fulfill a commitment made to the NRC in response to Generic Letter 2003-01, "Control Room Habitability" (references 1 and 2).
The commitment stated that DEK would submit proposed changes to the KPS TS based on the final approved version of TSTF-448, "Control Room Habitability."
The purpose of this letter is to re-submit the amendment request.
The originally submitted amendment request contained Attachment 2, "Marked-up Operating License and Technical Specification Pages." Due to an apparent printing error, some of the markups in the originally submitted Attachment 2 are not visible.
The remainder of this submittal is an unchanged version of what DEK submitted in its letter dated July 25, 2011. This submittal replaces the submittal dated July 25, 2011 in its entirety.
Enclosed is a compact disc (CD) containing this letter's Attachments and Enclosure. contains a description, safety evaluation, significant hazards consideration determination, and environmental considerations analysis for the proposed changes. contains marked-up Technical Specification pages.
contains marked-up Technical Specification Bases pages for information. Attachment 4 contains the revised RAA. contains an evaluation of two new manual actions credited in the revised RAA. contains the meteorological data A / o 19es~y~o27'e ai
Serial No. 11-025A Page 2 of 5 used to determine the atmospheric dispersion factor (X/Q) values used in the revised RAA and program files used to analyze the data (ARCON96 RSF and LOG files).
DEK requests approval of the proposed amendment by August 30, 2013.
Once approved, the amendment will be implemented within 90 days.
The KPS Facility Safety Review Committee has approved the. proposed. change and a copy of this submittal has been-provided to theo.. State of Wis consin in accordance with 10 CFR 50.91(b).
If you have questions or require additional information, please contact Mr. Craig Sly at 804-273-2784.

Supplemental Response," dated April 1, 2005. [ADAMS Accession No. ML050970303]
Commitments made by this letter:
- 1. The following guidelines will be included in the assessment of systems removed from service during movement of recently irradiated fuel:
- a. During fuel handling of recently irradiated fuel, ventilation system and radiation monitor availability (as defined in NUMARC 91-06) will be assessed, with respect to filtration and monitoring of releases from the fuel.
Following shutdown, radioactivity in the fuel decays away fairly rapidly. The basis of the Technical Specification operability amendment is the reduction in doses due to such decay. The goal of maintaining ventilation system and radiation monitor availability is to reduce doses even further below that provided by the natural decay.
- b. A single normal or contingency method to promptly close primary or secondary containment penetrations will be developed.
Such prompt methods need not completely block the penetration or be capable of resisting pressure.
The purpose of the "prompt methods" mentioned above is to enable ventilation systems to draw the release from a postulated fuel handling accident in the proper direction such that it can be treated and monitored.
Serial No. 11-025A Page 5 of 5
- 2. DEK will provide the necessary administrative controls to ensure that in the event of a fuel handling accident inside containment, any open containment penetration flow paths can and will be promptly closed (within 30 minutes). However, if it is determined that closure of any containment penetrations would represent a significant radiological hazard to the personnel involved; the decision may be made to forgo the closure of the affected penetration(s).
- 3. DEK will provide the necessary administrative procedures to:ensure tati e
event of a fuel handling accident inside containment, an open equipment hatch can and will be promptly closed following containment evacuation (within 45 minutes). However, if it is determined that closure of the containment hatch would represent a significant radiological hazard to the personnel involved; the decision may be made to forgo the closure of the containment hatch.
- 4. DEK will relocate the current technical specification requirements related to Radiation Monitor R-23 to the KPS Technical Requirements Manual as part of the implementation of this amendment.
The carbon copy (cc:) recipients of this letter will receive a compact disk (CD) which contains this submittal's Attachments and Enclosure.
