(Soo, I read some stuff about Chernobyl and I was really interested about how the entire disaster unveiled. So here's a small flash fiction style text about the last few minutes before the disaster..)

APRIL 26TH, 1986
V.I. Lenin Nuclear Power Plant, not far from Pripyat, Ukraine.

-
The man in the white lab coat nervously leaned over the control panel, his eyes glued onto the tens of small buttons and switches.

" This is insane. We have to reinsert some control rods back in, it won't hold if the reaction happens at such a pace.. "

Sweat dripped from his forehead as he spoke, his voice shaky and nervous. Rightfully so. His concern was met with a dull reply:

" We have to get the output considerably higher to get this test over with. Manually raise more of the control rods until we get it up to about seven hundred or so, should be standard.. "

A man standing in the middle of the half -moon shaped control room spoke in a stern voice. The walls of the room were lined with control panels, monitors.. one large monitor in the center of sight displayed a large diagram of the top part of the RBMK reactor. Shortly after the order was issued, another man of the many in the control room relayed:

" Eight control rods remaining inserted. "

His voice was also slightly uncertain, though it wasn't as obvious as with the white coat. Suddenly, after a pause of silence, another man hunched over a control panel looked back at the person that issued the command to raise the rods, with a look of slight distress in his face. He said, his voice occasionally interrupted by a quiet beeping sound coming from the control panel.

" Sir Datlov. The computers are suggesting we should immediately cancel the experiment, the reactor is clearly unstable. "

His voice was relatively calm despite the harrowing contents of his speech. Datlov didn't reply. He continued awaiting the core to increase it's output to a point where they can go through with the experiment. The look on his face suggested he was aware of the core's status.

1:23:04 AM
" Turbine eight has been disengaged. "

Silence. All of a sudden, one man from the crowd of workers hunched over control panels sprung back from his position and ran over to the central control panel. Datlov did nothing but raise his hand up and make a shocked expression as the man raised the cap protecting the SCRAM button and pushed his finger down onto it.

Further silence. Everyone backed down from their positions and stared at the man holding down the small red button. The control rods should've started entering the reactor by now to cancel the chain reaction.. however. Everyone stared at the central monitor.

The control rods stopped moving altogether.

1:23:40 AM
He stared in utter horror, leaning off of the metal railing and staring down at the top cover of the RBMK reactor. Most of the two-hundred or so control rods were bouncing up and down, steam rising from the reactor. His instincts overtook him, he started sprinting down the walkway, trying to exit the chamber. He ran as fast as he could. Behind him, the reactor continued to exhibit the mysterious control rod motion..

End of first part.
Planning to finish this by tomorrow. Probably.
Feel free to correct me on any mistakes I make.
