Blue = Uranium Light grey = non Uranium Black dot = Thermal neutron White dot with black outline = fast neutron (cant be absorbed by Uranium). Fast neutron will lose speed and turn into thermal neutrons over time Uranium absorbs 1 thermal neutron to produce 2-3 fast neutrons and turn into non Uranium up and down arrow to change Moderator (white rods with grey outline). moderator turns fast neutrons into thermal ones left and right arrow to control the Control rods (dark grey horizontal rods). control absorbs neutrons TargetU = Target of how much Uranium is in the simulation at any given time (depleted Uranium will be replaced) for example TargetU of 5 will set there to be 5 blue circles out of 120, while TargetU of 80 will set there to be 80 blue circles out of 120. will add water when i find the time to
