VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNITS 1 AND 2 i PROPOSED TECHNICAL SPECIFICATION CHANGES RADIATION MONITOR SETPOINT UPDATE  :]

Pursuant to 10 CFR '50.90, the< Virginia Electric and Power Company requests .j amendments, in the form ofichanges'to the Technical Specifications,.to Operating 1 License Numbers NPF 4 and NPF-7'for North Anna Power Station Units 01.and 2,  ;

respectively. a

' The proposed Technical Specifications changes will update the clarm setpoints for the i high range effluent ~ monitors. _The high range effluent monitors:and associated Technical Specifications were added due to accident monitoring concerns in NUREG ,

0737. The "Hi" and "Hi Hi" alarms were intended to provide warnings of impending site- 1 area or general emergencies. The criteria for. declaring a site- area or ge_neral emergency are in our Emergency Plan Implementing Procedures (EPIPs),Lwhich have j been revised-since the original setpoint' calculations were done. We wish to change l the setpoints to be consistent with currently' accepted EPIPs. Also, the Ventilation. Vent  !

and Process Vent monitors have.been modified to multiply the concentration by the-flow rate and report releases in units of- Ci/sec, a more relevant measure than the i currently approved Ci/cc. 1 o The proposed changes are presented in' Attachments 1 and 2 for Units 1 and 2, l respectively. The setpoints are not in our proposed MERITS Technical Specifications, j i: therefore a MERITS change is not attached. A. discussion of the proposed changes l Lwith the technical justification and safety evaluation of thel proposed changes is. "

provided in Attachment 3.

This request has been reviewed by the Station Nuclear -Safety and Operating Committee. It has been determined that this request does not involve an unreviewed ,

safety question as defined in 10 CFR 50.59 orLa significant hazards consideration as i defined in 10 CFR 50.92. The basis for our determination that no signification hazards  ;

consideration is involved is presented in Attachment 4.  ;
