PROBLEM TO BE SOLVED: To provide a carbon dioxide circulation type power generation system with the power of a pressurizer reduced.SOLUTION: A carbon dioxide circulation type power generation system comprises: a pressurizer which pressurizes supercritical phase carbon dioxide; a heat exchanger which heats the pressurized supercritical phase carbon dioxide; a combustor which heats the supercritical phase carbon dioxide supplied from the heat exchanger by combustion reaction using oxygen and fuel, and discharges first mixed fluid containing the supercritical phase carbon dioxide and steam; a turbine which is driven by the first mixed fluid; a cooler which is supplied with second mixed fluid containing the supercritical phase carbon dioxide and the steam discharged from the turbine through the heat exchanger, cools the second mixed fluid and discharges third mixed fluid containing the supercritical phase carbon dioxide and liquid phase water; and a separator which separates the third mixed fluid into the supercritical phase carbon dioxide and the liquid phase water and supplies the separated supercritical phase carbon dioxide to the pressurizer.
