Valery Legasov

Valery Alexeyevich Legasov (Template:Lang-ru; September 1, 1936, Tula, Soviet Union — April 27, 1988, Moscow, Soviet Union) was a prominent Soviet scientist in the field of inorganic chemistry, a member of the Academy of Sciences of the USSR. He is most famous for his work as the chief of the investigation committee of the Chernobyl disaster on April 26, 1986.

Early life and schooling

Valery Legasov was born in Tula into a family of civil workers. He graduated from the Mendeleev Moscow Institute of Chemistry and Technology and did his graduate studies in the Kurchatov Institute of Atomic Energy. He received the degree of Candidate in 1967 and his doctorate in chemistry in 1972, a remarkable achievement for a 36-year-old scientist. Legasov was a professor at the Moscow Institute of Physics and Technology. From 1983 until his death he was the chair of the department of Chemical Technology at the Chemistry Department of Moscow State University. He became a full member of the Academy of Sciences of the USSR in 1981.

Chernobyl

By the time of the Chernobyl disaster on April 26, 1986, Legasov had become the First Deputy Director of the Kurchatov Institute of Atomic Energy.[1] He became a key member of the government commission formed to investigate the causes of the catastrophe and to plan the mitigation of its consequences. He took the most important decisions to avoid repeat accidents and informed the government of the situation in the disaster area. He did not hesitate to speak to his fellow scientists and to the press about the safety risks of the destroyed plant and insisted on immediate evacuation of the entire population of Pripyat. In August 1986 he presented the report of the Soviet delegation at the special meeting of International Atomic Energy Agency (IAEA) in Vienna. His report displayed depth of analysis and full honesty in discussing the extent and consequences of the tragedy.[2]

On the second anniversary of the disaster, Legasov committed suicide by hanging himself from the stairwell of his apartment. Reportedly, before his suicide, he recorded himself on audiotape revealing previously undisclosed facts about the catastrophe. According to an analysis of the recording by BBC TV series Surviving Disaster: Chernobyl Nuclear Disaster,[3] Legasov claims political pressure censored mention of Soviet nuclear secrecy, which forbade even plant operators knowledge of previous accidents and known problems with the design of the reactor, in his report to the IAEA. It was implied that his suicide was at least partly due to his distress at not having spoken out about these factors at Vienna, the suppression of his subsequent attempts to do so, and the damage to his career that these attempts caused. The Bulletin of the Atomic Scientists also stated that Legasov had become bitterly disillusioned with the failure of the authorities to confront the design flaws.[4]

Legasov's suicide caused shockwaves in the Soviet nuclear industry. In particular, the problem with the design of the control-rods in Chernobyl type RBMK reactors was rapidly admitted to and changed.[3]

On September 20, 1996 Russian President Boris Yeltsin posthumously conferred to Legasov the honorary title of Hero of the Russian Federation for his "courage and heroism" shown in his investigation of the Chernobyl disaster.
