The invention discloses a mixed thermal circulation system based on a pressurized water reactor and a high-temperature gas-cooled reactor, which belongs to the technical field of nuclear power energy sources. Taking a pressurized water reactor of the electric power of 900MW as an example, the structure of a first loop system does not change; and compared with the second loop of an original pressurized water reactor, a second loop is added with two modular high-temperature gas-cooled reactors of the thermal power of 250MW and the electric power of 100MW as superheating reactors. After flowing out of a steam generator, all saturated steam is divided into two equal parts which enter superheaters in pressure shells of steam superheaters of the two high-temperature gas-cooled reactors respectively; and by heat exchange with high-temperature helium, the saturated steam has a certain superheat degree and flows together into a steam turbine to do work. The method is beneficial to enhancing the cycle thermal efficienc
