ii EOUIN .CR Operability Review: No Degraded or Nonconforming Condition exists per EN-OP-104.

Based on the below input from civil engineering, the identified conditions do not impact the structural integrity of the steel liner or the containment building.Therefore the vapor containment system remains operable.

No immediate reportability required per IP-SMM-LI-108.

During tours of the VC at the start of 2R21, Operations identified an additional area of liner insulation that is degraded on the 68'elevation of the VC behind column 7. This area has been added to WO 308669.This condition is not an immediate operability issue as the insulation is not structural and their sole design basis function is to protect the liner from hot liquid due to possible high energy line breaks and provide a vapor barrier against possible flooding of the 46' elevation.

The identified insulation degradation is minor and represents a very small percentage of the insulation coverage, and, as a result, the identified degradation will not adversely affect the design function of the steel liner.CR Action: Fix liner. Reference WO# 308669 Initial Action: CR Generated
