チェルノブイリ原子力発電所は、ウクライナ(旧ソビエト連邦)のチェルノブイリ近郊、プリピャチ市にあった原子力発電所です。原子炉の炉型は、黒鉛減速沸騰軽水圧力管型原子炉のRBMK-1000型(ソビエト型)で、1971年に着工され、1978年5月に1号炉が営業運転を開始しました。その後、1986年4月26日午前1時23分に4号炉が原発事故を起こし、世界中にその名が知られました。汚染された水、土壌、空気はまだ周辺の「立ち入り禁止区域」に影響を及ぼしています。

爆発した4号炉を覆う新安全閉じ込め構造物(NSC:New Safe Confinement)の建設が、2012年に始まり、完工。内部にコンピューター制御の換気装置を備えており、NSCは事故後に除染作業員たちによって突貫工事で建設された石棺に代わって4号機に残された放射性物質を向こう100年に渡って封じ込めるように設計されています。地上の様子はこちらです。

[Earthview Wonders] No.676: Chernobyl Nuclear Power Plant, Ukraine (ex-Soviet Union)🇺🇦

The Chernobyl Nuclear Power Plant is a decommissioned nuclear power station near the city of Pripyat, Ukraine. Reactor No. 4 was the site of the Chernobyl disaster in 1986 and the power plant is now within a large restricted area known as the Chernobyl Exclusion Zone. On April 26, 1986, a disaster occurred at Reactor N. 4, caused by a catastrophic power increase resulting in core explosions and open-air fires. This caused large quantities of radioactive materials and airborne isotopes to disperse in the atmosphere and surrounding land. The disaster has been widely regarded as the worst accident in the history of nuclear power in the world.

A giant steel shelter was slid into position over Chernobyl’s crumbling radioactive ruins. The New Safe Confinement (NSC) was deployed in November 2016 to contain radiation from doomed the nuclear power plant for 100 years. The local scenery on the ground is as follows.
