After passing through the HEX 1, helium (state 3) is expanded in the gas turbine to produce the electric power. The expanded helium (state 4) is further used in HEX 2 where it loses the energy and used to heat the helium (state 9) that goes inside the nuclear reactor. Before helium being compressed, it is further cooled down in HEX 3 (state 7).
