>> Recently, the ever-increasing use of fossil fuels for rapid industrial development and population significantly caused an environment pollution and global warming such as climate change. So research and development of sustainable and eco-friendly energy have been performed. Especially the interest in nuclear fusionfuel was significantly increased from the developed countries. The system of fusion energy production was tritiumseparation, storage and delivery, and purification. Republic of Korea is in charge of Storage and Delivery System (SDS) in the International Thermonuclear Experimental Reactor (ITER). Welding part of the SDS bottles for storingthe tritium is known to be susceptible to hydrogen embrittlement. In this study, conducted a study for the relaxationof the stability and hydrogen embrittlement of the weld area. The hydrogen heat treatment was processed throughthe Pressure-Composition-Temperature (PCT) device according to the time variation. Also mechanical properties suchas impact test and hardness test according to using the alkaline cleaning liquid for hydrogen embrittlement reliefand the fracture was observed by scanning electron microscopy (SEM) after the mechanical properties evaluation. |
