CALLAWAY ISI RELIEF REQUEST G System:
Reactor Coolant Category:
B-G-2 Component
Description:
Valve BB-8378B, a 3" cl.eck valve from Chemical and Volume Control System (CVCS) to Reactor Coolant System cold leg A.
Identified for inspection in the CVCS program plan.
Code Requirement:.
Visual inspection (VT-1) of bolting surfaces as required by item B7.70, category B-G-2.
Areas for Relief:
100% of the bolting, i
Basis for Relief:
Due to the encapsulation of the body to bonnet joint the bolting is inaccessible without removal of the welded encapsulation. The encapsulation is a modification supplied by the vendor (West-i inghouse) which was installed by Union Electric.
Alternate Test Method: None; provided the valve is not disessembled.
The reactor coolant system leakage detection system and ISI visual examinations for leakage l
will establish the integrity of the pressure l
boundary. When the encapsulation is removed the required exam will be performed.
