Evaluation of Cracking Susceptibility of Weldment Container for Nuclear Power Plant

Article Preview

Abstract:

The cracking susceptibility of a WSTE-51 steel for pressurized container of a nuclear power plant was evaluated. This evaluation was performed by means of the Controlled Thermal Severity Test and the Cold Cracking TEKKEN Test, as well as the VINCKIER Test for reheating cracking. Conventional mechanical tests and metallographic examinations were performed to characterize additional properties of the welding. The results indicated that the weldment has susceptibility to crack formation. Procedures to avoid this susceptibility were discussed.
