摘要:
In a reactor vessel (20) covered by cooling water (2), a tubular frame (10) with a bottom is hung within the cooling water (2) while still having an air environment in the interior, and the bottom section of the frame (10) is disposed within the reactor vessel (20), thereby achieving an air environment within the reactor vessel (20). Furthermore, since repairs to the reactor vessel (20) are performed by using the frame (10) while still having the air environment in the interior, this leads to the prevention of contamination and achieves improvements in working conditions such as preventing the generation of dust and reducing decontamination work. Accordingly, repairs can be performed in an air environment without draining the cooling water (2) within the reactor vessel (20), even in a state in which the reactor vessel (20) is covered by the cooling water (2).
摘要(中):
在由冷却水(2)覆盖的反应堆容器(20)中,具有底部的管状框架(10)悬挂在冷却水(2)内,同时在内部仍然具有空气环境,并且框架的底部 (10)设置在反应器容器(20)内,从而实现反应器容器(20)内的空气环境。 此外,由于通过在内部仍具有空气环境的情况下使用框架(10)进行对反应堆容器(20)的修理,所以能够防止污染,可以实现防止灰尘产生的工作条件的改善 并减少去污工作。 因此,即使在反应容器(20)被冷却水(2)覆盖的状态下,也可以在空气环境中进行维修,而不会排出反应器容器(20)内的冷却水(2)。
