Nuclear labor issues the most dangerous tasks within the industry is intensified by nuclear secrecy. On May 22, 1986, a nuclear fuel reprocessing plant at La Hague in Normandy, sustained a mechanical malfunction. Five workers were exposed to unsafe levels of radiation and hospitalized. On April 12, 1987, the Tricastin Nuclear Power Plant fast breeder reactor coolant leaked contaminating seven workers. In July 2008, approximately 100 workers were exposed to a radiation leak. The Chernobyl nuclear reactor meltdown occurred on April 26, 1986, in the Ukraine, during a test of the Unit 4 reactor systems. The explosion and fire caused by human error
Nuclear power in Ukraine much of Western USSR and Europe. It is considered the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster). The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy. Ukraine used to receive its nuclear fuel exclusively from Russia by the Russian company TVEL. Since 2008 the country also gets nuclear fuel from Westinghouse. Since 2014 Westinghouse's share of
