Aleksandr Fyodorovich Akimov (Russian: Александр Фёдорович Акимов; 6 May 1953 – 11 May 1986) was a Soviet engineer who was the supervisor of the shift that worked at the Chernobyl Nuclear Power Plant Reactor Unit 4 on the night of the Chernobyl disaster, 26 April 1986.
In 1976, Akimov graduated from the Moscow Power Engineering Institute, with the degree of specialist in engineering and automation of heat and power processes.
He began his career at the Chernobyl Nuclear Power Plant in September 1979. During his first years at Chernobyl, he held positions of senior turbine management engineer and shift supervisor of the turbine hall.
On 10 July 1984 Akimov was appointed to the position of shift supervisor of Reactor Unit 4.
On the night of 26 April 1986, Akimov was on duty as the shift supervisor of the 4th power unit. The reactor power level had been reduced, preparing for a planned safety test. Akimov refused to do the test due to its low and unstable condition but was overruled by Anatoly Dyatlov. However, the power reduction had been too abrupt, which put the reactor into a "poisoned" condition (a buildup of 135Xe, a strong neutron absorber), and made the reactor stall. Raising power after this point put the reactor into a potentially dangerous state, unbeknownst to the operators. The turbine was shut down. The test was completed and the AZ-5 (scram) button was pressed to shut down the reactor. The control rods had graphite moderators to speed up reaction, and the other part of the rods were made of boron to decrease reaction. As the rods were being inserted, the graphite tips of the control rods accelerated the reaction, creating neutron flux in the bottom of the core. This further increase in power caused the reactor to explode. The communications networks were suddenly flooded with calls and information. Akimov heard reports of massive reactor damage, but did not believe it, and as a result, relayed false information about the state of the reactor for hours thereafter.
Akimov worked with his crew in the reactor building after he learned the extent of the accident. They would try to pump water into the exposed reactor core until the morning hours of the 27th. Unknown to Akimov, he was exposed during his work to a lethal dose of 15 Gy of radiation.[page needed] At some point he gave deathbed confessions stating repeatedly: “I did everything correctly. I don't understand why it happened.” Akimov eventually succumbed to acute radiation syndrome two weeks after the disaster at the age of 33.
He was portrayed by actor Aleksandr Khoroshko in the 2004 Zero Hour television series, by Alex Lowe in the 2006 BBC production Surviving Disaster: Chernobyl Nuclear Disaster and by Sam Troughton in the 2019 HBO miniseries Chernobyl.
