Characterization of the removed-from-service Surry 2A steam generator

Conference ·
OSTI ID:5344703

A service degraded steam generator has been established in a unique research facility. This generator has undergone extensive nondestructive characterization from the primary side and photographic documentation of the secondary side. The unit is currently being disassembled with validation of the accuracy and reliability of primary side nondestructive examination (NDE) techniques, used during in-service inspections, as a major objective. This paper discusses variations found in multiple repeat primary side NDE, and presents evidence of deterioration documented via secondary side inspection techniques. 5 figs., 2 tabs.
