Recently, the third phase of China's first heating project fueled by nuclear energy, covering multiple prefecture-level cities, No.1 Warm-U-Clear operated by SPIC, was put into operation in Haiyang, Shandong Province.

In addition to Haiyang City in Yantai, the Haiyang nuclear power plant provides heating to Rushan City in Weihai. This not only realizes cross-regional interconnection and sharing of carbon-free heating, but also indicates success in replicating Haiyang's nuclear energy-fueled and carbon-free heating solution in Rushan, opening a new era of providing heating fueled by nuclear energy to two cities.

The project is the first in the world to develop and adopt a new mode of using a reheat regulating valve to automatically control the exhaust steam pressure of the high-pressure cylinder and successfully provide both heating and electricity with nuclear energy. Besides, the project has also successfully developed new technologies such as reactor electromechanical control, safety analysis of supplying heating and electricity with nuclear energy, and heat exchange over a long distance and with a large temperature difference suitable for large-scale heating supply through steam extraction. In addition to new technologies, new equipment innovations have also been made, including the equipment to control the pressure during steam extraction, the device to measure the flow of wet steam, and the simulator for supplying both heating and electricity with nuclear energy. These technological innovation achievements with fully independent intellectual property rights have laid an important foundation for the success of the large-scale cross-regional supply of heating fueled by nuclear energy.
