Atomic Reactor

Required Materials

 * Stripping material - material that used to start the chain reaction. Usually Californium (252Cf) or a mixture of radon and beryllium
 * Isolated cell - Iron hollow cell with isolation material inside made out of the lead.
 * LEU Rods (4 to 6) or HEU (Very rarely, as a result, you would probably get nuclear explosion)
 * Coolant liquid - (Mixture of water and Glycerol)
 * Moderation Material - Water
 * Coolant hydraulic piston

Construction
You will need to place an isolated cell at the place where no objects within a 5-meter radius. Load LEU (or HEU, madman) to the isolated cell by standing near the cell and using "transfer near LEU_Rod 4-6" command. Pour a water and coolant liquid into the cell. After that, set up a hydraulic piston from the reactor to the thermal converter. After turning the reactor on, it should change its color from grey to blue (Vavilov-Cherenkov effect). After turning off, Xenon's isotope will generate inside that will prevent turning the reactor on for 2 game days.

Another usage
The activated reactor can also be used to produce Plutonium (239Pu) that generally used as a component of atomic bombs (more efficient that HEU). But for this, you should also load 238U instead of LEU, therefore the efficiency of the reactor will be dropped down.

Radioactive wastes
After 5 activations LEU Rods transforms into Used Nuclear Fuel which can be used furtherly to obtain Plutonium
