Method for nuclear energy transformation of coal-fired power plant

The invention discloses a nuclear energy transformation method for a coal-fired power plant, and relates to the field of thermal power generation. According to the clean steam supply module capable of replacing the coal-fired power plant boiler, a nuclear reactor is used for providing heat energy, the nuclear reactor heats a working medium on the primary side of a steam generator in the steam supply module, and after a working medium on the secondary side of the steam generator is heated by the working medium on the primary side, the temperature rises to become a high-temperature working medium; a high-temperature working medium on the secondary side of the steam generator enters a steam turbine of the coal-fired power plant to do work through a high-temperature conveying pipeline; the high-temperature working medium becomes a low-temperature working medium after acting on a steam turbine of the coal-fired power plant, and the low-temperature working medium is condensed into a liquid state after passing throu
