Own and operate your very own AGR (advanced gas cooled reactor)! Press left/right to move charge machine. Press up/down to move fuel rods in/out of reactor core. Press I to increase circulation of CO2 coolant gas. Press R to reduce circulation rate of CO2. Try to maintain reactor temperature between 600 and 700 (degrees Celsius) to ensure optimum generating capacity and longevity of your graphite core. P.S. For best results, avoid meltdown of uranium oxide fuel pellets or blowing apart the graphite core due to excessive coolant pressure.
