| description | PROBLEM TO BE SOLVED: To provide a nuclear reactor plant improved in cycle efficiency by reducing compression work using condensability of carbon dioxide, and reducing exhaust heat generated by liquefaction of a coolant in a direct cycle nuclear reactor using carbon dioxide as the coolant. SOLUTION: This nuclear reactor plant has a nuclear reactor 1 and a turbine 2. A coolant in a supercritical state is heated by reactor heat, and the turbine 2 is directly driven by the heated coolant. The coolant in a gas state discharged from the turbine 2 after driving the turbine 2 is cooled and compressed into the supercritical state and then circulated again to the nuclear reactor 1. Carbon dioxide is used as the coolant. A prescribed rate of the coolant in the gas state discharged from the turbine 1 is liquefied and compressed in the liquid state, and the remaining portion is compressed in the gas state. |
