11RGINIA ELECTRIC AND POWER COMPANY MORTH ANNA POWER STILTION UNITS 1 AND 2 PROPOSED TECHNICAL SPECIFICATION CHANGE CONTAINMENT HIGH RANGE AREA RADIATION MONITORS AND NOBLE GAS HIGH RANGE EFFLUBL)*0NITORS -
TIME PERIOD FOR RESTORING CHANNELS TO OPERABLE STATUS Pursuant to 10 CFR 50.90, the Virginia Electric and Power Company requests an amendment, in the form of changes to the Technical Specifications, to the Operating Licenses for North Anna Power Station Units 1 and 2.
The proposed changes are enclosed.
Technical Specification 3.3.3.1 and Table 3.3-6 provide the operability requirements for radiation monitoring instrumentation.
Associated with each radiation monitor is an action statement should the radiation monitor be determined inoperable.
Currently, Action Statement 35 for the Containment High Range Area Radiation Monitors and the Noble Gas High Range Effluent Monitors requires that with the number of channels operable less than the minimum channels operable requirement, either restore the. inoperable channel (s) to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or initiate the preplanned alternate method for monitoring the appropriate parameter (s).
The action statement continues and requires the submittal of a Special Report within the next 14 days outlining the action taken, the cause of inoperability, and the I
plans and schedule for restoring the monitor to operable status.
In an effo; t to enhance operating flexibility and allow time for the proper calibration and troubleshooting on an inoperable radiation monitor, a change to Action Statement 35 is preposed.
The proposed change ~ is to initiate the l
preplanned alternate method for monitoring the appropriate parameter (s) of the radiation monitor within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and either restore the inoperable radiation 1
monitor to operable status within 7 days or submit a Special Report within 14 days. This change is consistent with NRC guidance provided in Generic Letter No. 83-37, NUREG-0737 Technical Specifications, dated November 1,1983.
