초록
Thermal and structural analyses were performed for a geological disposal system for spentnuclear fuel (SNF) with different canister materials: copper, titanium and ceramic. For thermal analysis,copper showed better thermal property than titanium and ceramic, although no significant differencewas observed. In structural analysis different patterns of stress distribution were simulated for copper,titanium, and ceramic, and ceramic did not meet a performance requirement for the geological disposalsystem under uniform and non-uniform load conditions.
