Control Room 4
Where it all happened!
This is the room in which operators attempted to run the safety test and pushed the reactor to its limits. The AZ-5 shutdown procedure was then activated, which, unknown to the operators had a fatal flaw, triggering the explosion and meltdown of the reactor.
Computer Room
The process computer for the RBMK nuclear reactors prior to October 1995 was SKALA (from the Russian which translates to "Control system of the devices of the Leningrad Nuclear Power Plant"). Dating back to the 1960s, it used magnetic core memory, magnetic tape data storage, and punched tape for loading software.

Main Circulation Pumps
The MCPs were responsible for ensuring a constant stream of water entered the reactor to remove the heat. During operation the heat turned the water to steam for use in the turbines. While the reactor was in a shutdown state, water was still required to keep it cool.
This memorial is dedicated to Valery Khodemchuk who was the senior operator of the main circulation pumps at the time of the accident. His body was never found.
Unit 5
Two more blocks, numbered five and six, of more or less the same reactor design, were planned at a site roughly a kilometre from the contiguous buildings of the four older blocks. Reactor No. 5 was around 70% complete at the time of block 4's explosion and was scheduled to come online approximately six months later, on November 7, 1986. In the aftermath of the disaster, the construction on No. 5 and No. 6 were suspended, and eventually cancelled in April 1989, just days before the third anniversary of the 1986 explosion. 6 further reactors were planned on the other side of the river. All 12 reactors were planned to be running until 2010.
