DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGE The proposed Technical Specification Change reflects a revision to Technical Specification 3/4.6.3.1 Table 3.6-1 to reflect the addition and deletion of containment isolation valves.
The addition of one direct-acting solenoid valve (TV-SS203A) is being used to replace two air-operated trip valves (TV-SS207A and TV-SS207B) to improve post-accident sampling capabilities.
The double isolation direct-acting solenoid valve is being installed to insure more reliable operation during accident conditions.
The addition of two air-operated trip valves (TV-DA203A and TV-DA203B) are being installed on the sample return line for the Post-Accident Sampling System in order to reduce radiation levels outside the containment when post-accident samples are being withdrawn from the reactor coolant system and containment sump. These valves will be normally closed and receive a Phase A signal to assure they are tripped closed on a safety injection signal.
The replacement of four manual valves (2-HC-13, 2-HC-29, 2-HC-18 and 2-HC-33) with sixteen remote operated manual valves (HC series valves) and the addition of remote manually operated double barrier isolation valves decreases personnel exposure to put the hydrogen analyzer and hydrogen recombiner into service and it also provides the capability of double isolation between containment atmosphere and all other systems.
The probability of occurrence or the consequences of a malfunction of equipment important to safety and previously evaluated in the FSAR is not increased because sampling system valve additions are designed consistent with codes and standards of the existing system and the replacement of containment isolation valves and the addition of double barrier isolation valves will maintain containment isolation capabilities.
The possibility of a different type of accident or malfunction than was previously evaluated in the FSAR has not been created because the sampling system valve additions do not change the characteristics of any system in operation during reactor operation and the containment atmospheric cleanup system is designed to Seismic Class 1 and single failure criteria.
The margin of safety as described in the BASIS section of any part of the Technical Specifications is not reduced because the upgrade and installation of containment isolation valves satisfies the seismic design criteria for safety related systems and continues to provide containment isolation integrity.
O
