| Abstract Scope |
SMR (Small Modular Reactor) refers to a reactor with a power capacity of up to 300MW per unit, smaller than conventional nuclear power plants. The conventional manufacturing methods for SMRs, casting and forging, have long production times. This study aims to eliminate these drawbacks by using the PM-HIP (Powder Metallurgy-Hot Isostatic Pressing) process with powder instead. The material selected is SA508 Grade 3, used in commercial nuclear power plants. To produce the powder, Vacuum Induction Melting Inert Gas Atomization (VIGA) and Electrode Induction Gas Atomization (EIGA) methods were used. HIP and heat treatment were performed, and the mechanical properties were evaluated to analyze differences based on the powder production method. Mechanical properties were measured using tensile and Charpy impact tests, and microstructures were analyzed using SEM. |
