Organisational structure at the Chernobyl Power Plant

It would be cool if someone created a chart or an infographic (with portraits) showing the "power structure" at CNPP, specifically as it was at the time of the disaster. There were quite a few supervisors and deputies, which can get a bit confusing. Let me start with the most well-known.

The Director: Viktor Bryukhanov. (I've read somewhere that he had a deputy for security, who was a KGB operative, and who gave orders to shut all the links to and from the city)

Chief Engineer: Nikolai Fomin

Deputy Chief Engineer for operation of Phase 1 (units 1 and 2): Anatoly Sitnikov

Deputy Chief Engineer for operation of Phase 2 (units 3 and 4): Anatoly Dyatlov

Present for their shift on the night of the disaster:

Plant Shift Supervisor: Boris Rogozhkin

Unit 3 Shift Supervisor: Yuri Bagdasarov

Unit 4 Shift Supervisor: Aleksandr Akimov

Phase 2 Reactor Shop Supervisor: Valery Perevozchenko

Deputy Turbine Shop Supervisor: Razim Davletbayev
