The invention provides a nuclear power plant waste heat heating system and method, the system comprises a first heat pump, a second heat pump, a steam-water heat exchanger, a heat supply circulation pipeline, a first closed cooling tower and a second closed cooling tower, and the heat supply circulation pipeline is connected with heat supply equipment, the first heat pump, the second heat pump and the steam-water heat exchanger. By arranging the first heat pump and the second heat pump, heat of the nuclear island equipment cooling water system and heat of the conventional island closed cooling water system are extracted respectively to heat return water of heat supply network circulating water of the heat supply circulating pipeline, and the heated heat supply network circulating water is heated through the steam-water heat exchanger and then sent to a user. Waste heat of the nuclear power plant is effectively utilized, and heat released to the surrounding environment by the nuclear power plant is reduced. By
