SUBJECT:
NORTH ANNA POWER STATION, UNIT NOS. 1 AND 2 - SUPPLEMENTAL INFORMATION NEEDED FOR ACCEPTANCE OF REQUESTED LICENSING ACTION RE: PROPOSED LICENSE AMENDMENT REQUEST ADOPTION OF TSTF-490, REVISION 0, REGARDING DELETION OF E BAR DEFINITION AND REVISION TO RCS SPECIFIC ACTIVITY USING THE CONSOLIDATED LINE ITEM IMPROVEMENT PROCESS (TAC NOS. ME0264 AND ME0265)
Dear Mr. Christian:
By letter dated December 17, 2008, (Agencywide Documents Access and Management System (ADAMS) Accession Number ML083530982), Virginia Electric and Power Company (Dominion),
submitted a license amendment request for North Anna Power Station, Unit Nos. 1 and 2 (North Anna 1 and 2). The proposed amendment would replace the current North Anna 1 and 2 technical specification (TS) limit on Reactor Coolant System (RCS) gross specific activity with a new limit on RCS noble gas specific activity. The noble gas specific activity limit would be based on a new dose equivalent Xe-133 definition that would replace the current E Bar average disintegration energy definition.
The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this amendment request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
The NRC staff has reviewed your application and concluded that the information delineated in the enclosure to this letter is necessary for the NRC staff to conclude that the application is acceptable.
In order to make the application complete, the NRC staff requests that Dominion supplement the application to address the information requested in the enclosure by January 28, 2009. This will enable the NRC staff to begin its technical review. If information responsive to the NRC staffs request is not received by the above date, the application will not be accepted for review pursuant to 10 CFR 2.101, and the NRC will cease its review activities associated with the application. If the application is accepted for review, you will be advised of any further information needed to support the NRC staffs technical review by separate correspondence.
The information requested and associated time frame in this letter was discussed with Mr. Thomas Shaub of your staff on January 13, 2009.
Please contact Donna Wright at 301-415-1864, if you have any questions.
Sincerely,
/RA/
John Stang, Senior Project Manager Plant Licensing Branch II-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-338 and 50-339

1.)
The application dated December 17, 2008, refers to an NRC staff Safety Evaluation (SE),
described as Reference 1, dated September 27, 2006 (ADAMS Accession No. ML062700612). This document is not publicly available. The NRC acknowledges that reference to ADAMS Accession No. ML062700612 was mistakenly contained in the notice of availability of model application for this TS improvement that was published in the Federal Register (72 FR 12217). However, since the submittal states that the methodology described in this NRC staffs SE was applied to develop the proposed TS changes, it is not clear how this was accomplished. In order to make the application complete, the NRC staff requests that Dominion supplement the application to provide a corrected reference for the methodology used to develop this proposed TS change as well as a correct reference to the public version of the NRC's SE for this Technical Specification Task Force Traveler.
