(Radioactive) particles in the containment atmosphere Explanation: ここで言う粉塵とは次のリンクで説明されている airborne particulate matter のことです。一般的には particules と表現すれば十分だと思います。 https://en.wikipedia.org/wiki/Airborne_particulate_radioacti... 補足的情報ですが、原子炉のcontainment ventilation system にはこの粉塵が大気に放出するのを防ぐ high-efficiency particulate air (HEPA) filter が装備されていると言われています。 次のリンクに参考になる記述(以下に引用)があります。 http://allthingsnuclear.org/containment-venting-is-cooling-b... “Some emergency situations, however, require venting directly from the drywell to reduce the pressure. This also happened at Fukushima. If the RHR system were operating and could spray water into the drywell, this water would help remove radioactive particles and gases from the containment atmosphere, preventing this material from being released to the environment during venting.” |
