Findings a.
Nonconformance See Notice of Nonconformance The procedures dealing with handling and storage pertain to items during the manufacturing process, and not long term storage after the vessel has been completed.
RSV-A's customer has directed that the completed reactor vessel is not to be shipped until July,1981.
The need for use of the manufacturing area occupied by the com-pleted reactor vessel necessitated movement of the vessel to outside the facility.
The vessel's total expected time in outside storage will be approximately six months.
Procedures have not been developed to provide for storage, pre-servation, and inspection of the reactor vessel during outside storage.
Visual observation by the NRC inspector disclosed entrapped water in various flange areas and the beginning stages of corrosion.
b.
Unresolved Items None.
C.
