The invention discloses a high-temperature heat supply system and method for a pressurized water reactor nuclear power unit. The system comprises a molten salt pond, a molten salt pump, a low-temperature steam heating exchanger and a pressurized water reactor nuclear power unit steam supply module. An outlet of the molten salt pond is connected to an inlet of the molten salt pump, an outlet of the molten salt pump is connected to a first inlet of the low-temperature steam heating exchanger, and a second outlet of the low-temperature steam heating exchanger is connected to an inlet of the pressurized water reactor nuclear power unit steam supply module. And an outlet of the pressurized water reactor nuclear power unit steam supply module is connected to a second inlet of the low-temperature steam heating exchanger. The method can replace a start-up boiler to meet the requirement for steam consumption of unit start-up; peak regulation electric energy can be stored, and good economical efficiency is achieved; th
