Abstract
A tip-over test of the 1/3 scale model is conducted to verify the tip-oner analysis of a dry concrete storage cask under a hypothetical accident condition. The tip-oner analysis is executed using the velocity at each point which are determined from the initial angular velocity as the initial conditions of the model just before the impact. To confirm the structural integrity of the canister of a dry concrete storage cask, the non-detective testing such as Liquid Penetrants testing and Ultrasonic Testing are conducted. The strains and tile accelerations acquired by the tip-over test are compared with those by the analysis to verify the tip-over analysis. The lid of a storage calk are plastically deformed at the impact point. Liquid
고연소도 PWR 사용후연료 건식저장용기의 전복사고조건에 대한 해석 검증을 위한 1/3 축소모델의 시험을 실시하였다. 전복해석은 전각각도에 따른 위치에너지와 동일한 운동에너지를 가지는 초기각속도를 이용하여 결정된 각 점에서의 속도를 충돌직전 모델에 대한 초기경계값으로 입력하여 해석하였다. 전복각도
