Indirect Helium Cooled Fast Breeder Reactor of Enhanced Safety with Helium Turbine System for Electricity Generation and Freshwater Production Unit

Abstract

In consideration of recent incidents caused by leakage of Na in the LMFBR, studies have been conducted on the indirect He cooled fast breeder reactor with the He turbine power generation system(GT-HeFBR)and freshwater desalination production unit in the secondary loop. Desalination is conducted by use of exhaust heat from He turbine. The plant has the features of high safety, reliability, thermal efficiency and economic competitiveness. Reactor performances are enhanced by use of the long annular type He passage in the reactor in the primary loop. Economic competitiveness is attained by the electricity generation of high efficiency. The He turbine electric power generation of the maximum system efficiency of 44% and the efficient production of freshwater for the local use are performed in the secondary loop. The processes give a total thermal efficiency of about 90%.
