CLOSURE MECHANISM OF RADIOACTIVE SUBSTANCE ACCOMMODATION REGION
PROBLEM TO BE SOLVED: To provide a closure mechanism of a radio active substance accommodation region that does not need to replace sealing members, such as a packing and a gasket, and can execute reliable sealing without particularly requiring to keep positional accuracy of a closing member, such as a door, high at the time of closing.SOLUTION: An opening 2 of a radioactive substance accommodation region 1 is configured to be sealed with a liquid sealing mechanism, i.e. a sealing mechanism via liquid by a closing door 11. The closing door 11 includes an annular projection 12 projecting downward. The radioactive substance accommodation region 1 includes an annular groove 4 configured to be able to accommodate liquid and circling around outside of the opening 2. When the closing door is lowered, a lower end side of the annular projection goes under the liquid in the annular groove, and thereby the opening of the radioactive substance accommodation region is sealed by the closing door.SELECTED DRAWING: Figure 3
【課題】パッキンやガスケットなどの封止用部材の交換が不要で、しかも、閉止時において、扉体など閉止部材の位置精度を高く保持することを特に必要とせずに、信頼性の高い封止を行うことが可能な放射性物質収容領域の閉止機構を提供する。【解決手段】放射性物質収容領域１の開口部２が、閉止扉１１によって、液体を介した封止機構である液封機構により封止されるように構成する。また、閉止扉１１が、下方に突出した環状突出部１２を備え、放射性物質収容領域１が、液体を入れることができるように構成された、開口部２の外側を周回する環状溝部４を備え、閉止扉を下降させたときに、環状突出部の下端側が、環状溝部内の液体に没入することにより、放射性物質収容領域の開口部が、閉止扉により封止されるように構成する。【選択図】図３
