Description

Mechanical properties and fracture toughness testing of substrate pressurizer material is performed on simulated cast with same chemical composition and same production treatment as original material in Nuclear Power Plant. Tests were performed on artificially 2 years aged specimens at service temperature 300 deg C. The fracture toughness values in term of J-integral=81 N/mm was determined according to ASTM test procedure. Mechanical properties of clad and weld metal are taken from ASME Boiler and Pressure Vessel Code. Considering the material and physical properties of pressurizer bottom and internal pressure, the numerical analysis of displacement and stress distribution through the thickness was performed
