Abstract

See full text

A method of varying the power generated by a nuclear power plant having a closed loop power generation circuit making use of helium as the working fluid. The method includes the step of varying the helium inventory in the power generation circuit. To this end, the nuclear power plant includes a helium inventory control system which is selectively connectable in flow communication with the power generation circuit. To increase the power generated, helium is fed from the helium inventory control system to the power generation circuit and to reduce the power generated, helium is fed from the power generation circuit to the helium inventory control system. The helium inventory control system includes a booster tank containing helium at a pressure higher than in the power generation circuit to permit helium to be fed to the power generation circuit at a high point of the circuit.
