Purifying apparatus of radioactivity diffusion proof water for used nuclear fuel building for nuclear power plant

摘要

The present invention is a rapid, efficient, and simple water purification effect for the purification and recycling of turbid radiation diffusion water, and the radiation diffusion prevention water purification device for the spent fuel building of a nuclear power plant that can be circulated for various spent fuel buildings. In order to provide a, equipped with four sets of filters (2 to 5) that can be selectively filtered over four stages according to the turbidity of the radioactive diffusion preventing water in the trolley 30, the filtered water treated in the previous step and after Treated filtrate is equipped with check valves (6 to 9) to prevent backflow to the pretreatment filter and the aftertreatment filter side, and the spent fuel of the nuclear power plant equipped with a discharge pipe shutoff valve (10 to 12) required for selective filtration. Characterized in the configuration of the radiation diffusion prevention water purification device for buildings.
