DRAINAGE FACILITY IN BUILDING FOR HANDLING RADIOACTIVE MATERIAL
PROBLEM TO BE SOLVED: To prevent at least installation work from being largely scaled when a normal drainage facility is applied to the existing floor in a building for handling a radioactive material.SOLUTION: Inside a hatch cover installed in the hatch provided on the floor in a building for handling a radioactive material, a water intake is provided on the upper floor side and a drainage channel having a drainage port is provided on the lower floor side. Toward the drainage port from the water intake, height from the bottom of the hatch cover is kept in the same level or becomes lower in the drainage channel. Furthermore, at the drainage port, a dumper is provided having airtightness capable of opening operation by water self-weight.
【課題】本発明は、通常の排水設備を既存の放射性物質取扱建屋内の床に適用した場合、少なくとも設置工事する場合の大規模な工事となることを防止する。【解決手段】本発明は、放射性物質取扱建屋内の床に設けられたハッチに設置されるハッチカバー内部に、床の上階フロア側に取水口を、床の下階側に排水口を備える排水路を設ける。また本発明は、排水路が取水口から排水口に向けて、ハッチカバーの底部からの高さが同じか、低くなっていく。さらに、本発明は、排水口に水の自重で開動作が可能な気密性を持つダンパーを設ける。【選択図】 図１
