O ATTACllMENT 2 DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGE
DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGE The proposed Technical Specification revises North Anna 1 Technical Specification 3/4.6.3.1 Table 3.6-1 to reflect the addition and deletion of containment isolation valves.
The Fire Hose Rack Standpipe System is an extension of the Interior Fire Protection System. The fire hose rack standpipe piping is routed through the Auxiliary Building to penetration no. 34 of Unit 1 Containment. Containment isolation is provided by one manual isolation valve (1-FP-274) and one check valve (1-FP-272).
The Steam Generator Wet Layup Circulation System is being implemented to add forced circulation capabilities to each of three Steam Generators. Each Steam Generator will have a new 2 inch penetration installed through the upper shell wall with piping running to existing spare Containment penetrations. Return flow to each Steam Generator will be provided through existing Steam Generator blowdown lines. The installation of a new piping line from each of three Steam Generator upper shells to a Containment penetration requires the installation of six manual isolation valves (1-WT- 465, 1-WT-468, 1-WT-488, 1-WT-491, 1-WT-511, and 1-WT-514).
The addition of two (2) direct-acting solenoid valves (TV-SS103A and TV-SS103B) will be used to replace two (2) air-operated trip valves 4 (TV-SS107A) and TV-SS107B) in the Residual Heat Removal System Sample Lines.
i The double isolation direct-acting solenoid valves are bing installed to j provide increased assurance of reliable operation during accident conditions.
The valves will be normally closed and receive a Phase A signal to assure they are tripped closed on a safety inj ection signal. These modifications are required to meet the provisions of NUREG-0737, II.B.3, Post-Accident Sampling.
The addition of two air-operated Phase A trip valves (TV-DA103A and TV-DA103B) are being installed on the Post-Accident Sampling System return lines. These valves will reduce radiation levels outside containment should post-accident samples be required to be withdrawn from the reactor coolant system and containment sump. These modifications are required to meet the provisions of NUREG-0737, II.B.3, Post-Accident Sampling.
Four (4) manual isolation valves (1-HC-12, 1-HC-31, 1-HC-16, and 1-HC-28) in the hydrogen-recombiner and analyzer system are being replaced with sixteen (16) remote-manual valves (HC-series valves) to upgrade the hydrogen recombiner and analyzer system. The addition of these remote-manual isolation valves will reduce radiation levels outside the containment should the hydrogen analyzer and recombiner be required to be in service for post-accident conditions.
Eight of these valves are in the suction and return lines for the hydrogen analyzers. These remote-manual valves are TV-HC-200A&B (in series), TV-HC-201 A&B (in series), TV-HC-202 A&B (in series) and TV-HC-203 A&B (in series).
Eight of these valves are in the suction and discharge lines for the hydrogen recombiners. These remote-manual valves are TV-HC-204 A&B (in series)
TV-HC-205 A&B (in series), TV-HC-206 A&B (in series ) and TV-HC-207 A&B (in series).

, 1 o.
The probability of occurrence or'the consequences'of'a malfunction of equip-ment important to safety and previously evaluated in the FSAR is not increased because the upgrading and the installation of the atove containment isolation valves meets the reqdirements for Category I Containment Isolation Valves as specified in the FSAR.
The possibility of a different type of accident or malfunction than was previously evaluated in the FSAR has not been created by the additien of these containment isolation valves because double. barrier protection is provided to assure that no single failure will result in a loss of containment integrity.
The margin of safety as described in the BASIS section of any part of the Technical Specifications is not reduced because the addition of containment isolation valves provides, containment integrity and protects safety related equipment.
