Re: Chernobyl - graphite fire
Not quite. The reactor was coming up to its summer shutdown and it was planned to run a test to see if the rotational energy in the turbine could be used to power essential electrical loads should the reactor trip - if so it wouldn't be necessary to have standby diesel generators running continuously just in case. Unfortunately they botched the process of reducing the reactor output and grossly undershot the level needed for the test. The control rods were withdrawn far beyond normal in an attempt to correct, resulting in a power surge and explosion.
