         2 . The system according to  claim 1 , wherein the coolant comprises water, the vapor comprises saturated water vapor, and the power generation apparatus comprises at least one steam turbine. 
     
     
         3 . The system according to  claim 2 , wherein the power generation apparatus comprises a plurality of steam turbines in series, and wherein the system further comprises:
 a steam-water separator for separating supersaturated steam from the vaporization of the water in the cooling apparatus into water and saturated water vapor;   a line for supplying a part of the saturated water vapor to a first steam turbine of the plurality of steam turbines;   a superheater for superheating supersaturated exhaust steam from the first steam turbine by another part of the saturated water vapor to turn the exhaust steam to a saturated state or lower; and   a line for supplying the superheated exhaust steam from the superheater to a second steam turbine of the plurality of steam turbines.   
     
     
         4 . The system according to  claim 1 , wherein the cooling apparatus comprises a flow path of the coolant located outside of the catalyst layer to cool the catalyst layer by the coolant. 
     
     
         5 . The system according to  claim 3 , wherein the plurality of steam turbines comprises a high-pressure turbine, a medium-pressure turbine, and a low-pressure turbine, and the superheater comprises a first superheater and a second superheater,
