Chief engineer Fomin arrived in the block 4 control room at 4:30 a.m. At 3:30 a.m., Telyatnikov contacted Akimov, asking what was happening to his firemen; Akimov sent him a dosimetrist. Dyatlov then received the report of Perevozchenko that pump operator Khodemchuk was still unaccounted for. His body was never recovered and is entombed in the nuclear reactor's debris.[14][15]. The explosion occurred, the air filled with dust, power went out, and only battery-powered emergency lights stayed in operation. The communication lines were cut during the explosion. They ran through the de-aerator gallery to the right to the VRSO unit elevator, found it destroyed, so climbed up the staircase instead, towards level 36; they missed Kurguz and Genrikh, who used another stairwell. [1] In testimony at the trial, several witnesses recalled Dyatlov remaining in the room at this point,[2] but did not report any disagreements or "serious discussions" related to the increase in power or at any other point during the test.[3]. According to The Trumpet, Ananenko, Bespalov, and posthumously Boris Baranov, were presented state awards by Ukrainian President Petro Poroshenko for their bravery.

Sitnikov then assisted Akimov and Toptunov with feeding water into the reactor; the water, however, flowed through the severed pipes into the lower levels of the plant, carrying radioactive debris and causing short circuits in the cableways common to all four blocks. For some, like the three Chernobyl divers, heroics come quietly as the result of a quashed threat. The Chernobyl Disaster was a nuclear accident that occurred on April 26, 1984, in Ukrainian SSR. The Commission for Investigation and Liquidation of the Consequences of the Chernobyl Nuclear Power Plant Accident made a decision to cool the core from below with liquid nitrogen. As the control rods dropped into the core, the graphite displacers that made up the last few meters of the rods introduced additional moderation and hence reactivity into the reactor system. That word is Chernobyl. In control room at desk T with Kirschenbaum at the moment of explosion. With full knowledge of the danger and with basic scuba gear and a dodgy lamp, they dived down to find the valve. [25], Two decades after the accident, the Chernobyl Forum Report showed that the first responders and clean-up workers, who were the people exposed to the highest level of radiations, still had the highest rates of depression and post-traumatic stress disorder. On 28 April 1986, three men knowingly took on a likely suicide mission to prevent a steam explosion. Three men volunteered: Alexei Ananenko, an engineer who knew the location of the valves, Valeri Bezpalov as a colleague, also employed at the power plant and Boris Baranov, who never descended into the water, was a soldier of the Soviet army, whose mission was to light their way underwater. The stairs on the right side were damaged; he managed to escape by the stairs on the left.
