HEAT TRANSFER TESTING DEVICE OF CONTAINER USED FOR TRANSPORTING AND/OR STORING SPENT FUEL

To provide a heat transfer testing device capable of efficiently performing a heat transfer test by reducing time required for inserting a pseudo heat source heated to temperature obtained by simulating the amount of heat generation of a spent fuel into each of a plurality of storage spaces demarcated by a lattice-like basket in preparation work of a heat transfer test.SOLUTION: When a temporary cover is lowered toward a container body from above the container body in a state in which each of a plurality of storage spaces is open upward, at least movement to a direction of separating downward from the temporary cover is restricted among respective movements of a plurality of pseudo heat sources such that each of the plurality of pseudo heat sources is maintained to be suspended with respect to the temporary cover, and a lower end of each of the plurality of pseudo heat sources abuts on a bottom face of the container body in a state in which each of the plurality of pseudo heat sources is stored in a corresponding storage space and the temporary cover is mounted to the container body, thus canceling a state in which each of the plurality of pseudo heat sources is suspended with respect to the temporary cover.SELECTED DRAWING: Figure 1 【課題】伝熱試験の準備作業のうち、使用済燃料の発熱量を模擬した温度に加熱される模擬熱源を格子状のバスケットによって画定された複数の収容空間の各々に挿入する作業に要する時間を短縮して、伝熱試験を効率よく行うことができる伝熱試験装置を提供する。【解決手段】複数の収容空間の各々が上方に向かって開口している状態の容器本体の上方から仮蓋を容器本体に向かって降下させるときには、複数の模擬熱源の各々が仮蓋に対して吊り下げられた状態を維持するように、複数の模擬熱源の各々の動きのうち少なくとも仮蓋から下方に離れる方向への動きを拘束し、複数の模擬熱源の各々が対応する収容空間に収容され且つ仮蓋が容器本体に取り付けられた状態では、前記複数の模擬熱源の各々の下端が前記容器本体の底面に接触することで、前記複数の模擬熱源の各々が前記仮蓋に対して吊り下げられた状態を解除する。【選択図】図１
