NORTH ANNA POWER STATION UNITS 1 AND 2 REPLACEMENT TS PAGE 1.1-5 TO INCLUDE UPRATED POWER PROPOSED LICENSE AMENDMENT REQUEST ADOPTION OF TSTF-490. REVISION O. REGARDING DELETION OF E-BAR DEFINITION AND REVISION TO RCS SPECIFIC ACTIVITY In a letter dated December 17, 2008 (Serial No. 08-0729),
Dominion requested amendments, in the form of changes to the Technical Specifications (TS) to Facility Operating License Numbers NPF-4 and NPF-7, for North Anna Power Station Units 1 and 2,
respectively.
The proposed amendment would replace the current Technical Specifications limits on reactor coolant system (RCS) gross specific activity with a new limit on RCS noble gas specific activity.
Since this submittal, Dominion submitted and received approval of a measurement uncertainty recapture (MUR) amendment. The MUR amendment was issued by the NRC on October 22,2009 and affected a TS page that was also included in the proposed RCS activity change.
As a consequence, the pages initially submitted for the proposed RCS activity change need to be updated to address the page repagination that occurred. to this letter provides the typed TS page 1.1-5 that addresses the recent changes that occurred due to the MUR amendment.
Please use this page when completing the review of the proposed RCS activity amendment.
If you have any questions or require additional information, please contact Mr. Thomas Shaub at (804) 273-2763.
Very truly yours,

PHYSICS TESTS QUADRANT POWER TILT RATIO (QPTR)
RATED THERMAL POWER (RTP)
REACTOR TRIP SYSTEM (RTS) RESPONSE TIME SHUTDOWN MARGIN (SDM)
Definitions 1.1 component, or device to perform its specified safety function(s) are also capable of performing their related support function(s).
PHYSICS TESTS shall be those tests performed to measure the fundamental nuclear characteristics of the reactor core and related instrumentation.
These tests are:
- a. Described in Chapter 14, Initial Tests and Operation, of the UFSAR;
- b. Authorized under the provisions of 10 CFR 50.59; or
- c. Otherwise approved by the Nuclear Regulatory Commission.
QPTR shall be the ratio of the maximum upper excore detector calibrated output to the average of the upper excore detector calibrated outputs, or the ratio of the maximum lower excore detector calibrated output to the average of the lower excore detector calibrated outputs, whichever is greater.
RTP shall be a total reactor core heat transfer rate to the reactor coolant of 2940 MWt.
The RTS RESPONSE TIME shall be that time interval from when the monitored parameter exceeds its RTS trip setpoint at the channel sensor until loss of stationary gripper coil voltage. The response time may be measured by means of any series of sequential, overlapping, or total steps so that the entire response time is measured. In lieu of measurement, response time may be verified for selected components provided that the components and methodology for verification have been previously reviewed and approved by the NRC.
SDM shall be the instantaneous amount of reactivity by which the reactor is subcritical or would be subcritical from its present condition assuming:
