NUCLEAR POWER PLANT AND METHOD OF OPERATING THE SAME

摘要

A nuclear power plant makes use of a high temperature gas cooled reactor. Under certain circumstances, the possibility exists that the temperature of gas entering various components of the plant exceeds desired operating parameters. To prevent this, the temperature of the gas entering at least one of the components of the power plant is monitored and, should the temperature of the gas exceed a predetermined temperature, cooler gas is mixed with the gas whose temperature had exceeded the predetermined temperature, to reduce the temperature of the gas. Accordingly, the plant includes at least one coolant feedline leading from a source of coolant gas, typically at a point in the power generation circuit where the temperature of the gas is relatively low, to a position upstream of the component. A coolant valve is mounted in the coolant feedline to regulate the flow of coolant gas therethrough.
