Dark Light Dwellers (UN-D-7983)
The control rods can also be completely lowered to shut the reactor down in extreme cases.

Carbon dioxide gas is pumped through the reactor to take the heat away, and the hot gas then heats water to make steam, which drives a turbine to generate power.

The procedure is generally safe, and only through human error or faulty equipment do problems occur. However, in the nuclear incident of 1982 there was third element that conspired to cause an almost fatal incident.

The Dark Light Dwellers are thought to consist of sub atomic particles that appear to act in a similar way to neutrons.

When the Daemon suddenly appeared within the main reactor chamber, its presence produced an increased amount of neutron-like matter within the chamber.
