A nuclear reaction byproduct that heats up quickly under pressure. Uranium is used in nuclear reactors IRL to create heat that makes steam, the steam is used to spin a turbine and condense back into water, the turbine speed is in a generator for power. Due to the reaction creating steam pressure increases heating it up. The rate of change in heat from pressure is determined exponentially. Uranium will slowly cool down under low, or no pressure. At 256 pressure temp will increase by 83.01C every frame.
