The identification of the indication required the removal of insulation in order to complete the inspection. The
unidentified leakage rate is below Tech Spec limits and the leak location is within the isolable boundary of the 'B'
Reactor Recirculation Pump. This failure constitutes a welding or material defect in the primary coolant system that is not acceptable under
ASME Section XI for
ASME Code Class 1 piping.
