Here: have at it with a Swedish nuclear power plant simulator.
Raise and lower the control rods, turn pumps on and off, open
and close valves, just make sure you don’t blowup anything. Go
look at the Chernobyl tour to see what happens when you mess up.
The original page includes this context: The control-room
operators of the Kärnobyl nuclear power plant are telecommuting
and are running the plant through the Web. However, the mean
time between failure for the components of Kärnobyl is not
great. Try to keep the reactor stable when component failures
occur! tags: chernobyl, control rods, control room, control room
