Chernobyl Nuclear Power Plant Chernobyl, from the border of Ukraine and Belarus and about north of Kiev. Construction of the plant and the nearby city of Pripyat, Ukraine to house workers and their families began in 1970, with Reactor N. 1 commissioned in 1977. It was the third nuclear power station in the Soviet Union of the RBMK-type (after Leningrad and Kursk), and the first nuclear power plant on Ukrainian soil. The completion of the first reactor in 1977 was followed by reactor N. 2 (1978), N. 3 (1981), and N. 4 (1983). Two more blocks, numbered 5 and 6, of more or less
Nuclear power phase-out cycle, from mining to reactor operation to waste disposal, the radiation dose is cited as 136 person-rem/year, the dose is 490 person-rem/year for an equivalent coal-fired power plant. The 1979 Three Mile Island accident and 1986 Chernobyl disaster, along with high construction costs, ended the rapid growth of global nuclear power capacity. A further disastrous release of radioactive materials followed the 2011 Japanese tsunami which damaged the Fukushima I Nuclear Power Plant, resulting in hydrogen gas explosions and partial meltdowns classified as a Level 7 event. The large-scale release of radioactivity resulted in people being evacuated from a 20 km
