China has started up its first commercial nuclear cogeneration system, using two newly operational AP1000 reactors at the Haiyang Nuclear Power Plant to heat 700,000 square meters of housing.
Shandong Nuclear Power Co. (SDNPC), a subsidiary of State Power Investment Corp. (SPIC), and owner of the Haiyang plant, on Nov. 15 said the first phase of the Shandong Haiyang Nuclear Energy Heating Project was formally put into operation.
Details about how Haiyang is producing heat are unclear. Generally, in a nuclear cogeneration process, a coolant recovers the thermal energy released by fission in the reactor core. That energy is usually converted into electrical power through a turbine generator, but when heat is part of the final use, it can be used directly for district heating and cooling, process steam, desalination, hydrogen, or steel manufacturing.
