In this paper a power generation system is proposed for electricity generaton and desalinated freshwater production by an indirect hot He reactor by burning up Pu partitioned from spent fuel from Light Water Reactors(LWR), in order to extinct Pu as an energy resourse and prevent it from being converted to nuclear weapons. Heat released in burning up Pu fuel decreases with time, and, therefore, unlike the performance of a conventional LWR power plant, thermal energy is produced from new Pu fuels by properly pulling out control rods from them. A new system, using 950°C He at the reactor exit, generates electricity by He turbine and produces desalinated freshwater using turbine exhaust heat in the secondary loop. When Pu partitioned from the spent fuel of LWR of 1000 MWe is burned up, it is shown that the GT-PuHHR having 316 MWt generates 137 MWe with 43.7% thermal efficiency, produces 6275 ton / day freshwater and attains about 90% total plant thermal efficiency.
