Bryukhanov Reactor Damage Confirmation
Receives increasingly clear evidence that the Unit 4 reactor has been destroyed despite earlier assumptions that it remained intact.
Chernobyl Initial Briefings
Receives initial government briefings as Soviet authorities begin assessing the scale of the Chernobyl reactor accident.
Dyatlov 200 MW Test Continuation
Accepts carrying out the test after reactor power is stabilized at roughly 200 megawatts thermal.
Dyatlov Backup Control Room Check
Checks the backup control area and attempts further shutdown actions after the Unit 4 explosions.
Dyatlov External Damage Survey
Goes outside with radiation-monitoring staff to inspect damage around the destroyed Unit 4 building.
Dyatlov Low-Power Test Decision
Supports continuing the turbine rundown test after reactor power falls far below the originally intended level.
Dyatlov Manual Control Rod Order
Orders personnel to investigate whether jammed control rods can be lowered manually after the explosions disrupt the normal drive mechanisms.
Dyatlov Manual Rod Order Cancelled
Abandons the attempted manual control-rod intervention after the scale of structural destruction makes the task impractical and dangerous.
Dyatlov Operating Logs Collected
Collects operating records from the control room before leaving to report the developing situation to senior plant management.
Dyatlov Post-Explosion Cooling Order
Orders emergency efforts to keep water flowing toward the damaged reactor after the explosions.
Dyatlov Radiation Sickness Symptoms
Develops weakness and vomiting after prolonged exposure in contaminated plant areas during the first hours following the accident.
Dyatlov Sends Injured Workers for Treatment
Directs injured workers encountered in the plant corridors toward medical treatment as the emergency response spreads through the damaged unit.
Dyatlov Turbine Hall Damage Inspection
Observes fallen roofing, fires and leaking oil while examining damage in and around the turbine-hall area after the explosions.
Dyatlov Turbine Rundown Supervision
Remains in the Unit 4 control room as the turbine rundown test begins at 01:23.
Dyatlov Unit Four Staff Reduction
Orders personnel no longer needed in the Unit 4 control room to move away from the increasingly hazardous operating area.
Dyatlov Unit Three Shutdown Order
Orders Unit 3 to be shut down as the scale of the emergency around Unit 4 becomes clearer.
Fomin Accident Cleanup Participation
Participates in the early management of cleanup and stabilization work after the destruction of Unit 4.
