  Shandong Nuclear Power Company, a subsidiary of State Power Investment Corporation (SPIC) and the owner of Haiyang plant has carried out the second phase of Haiyang Nuclear Power Heating Project One since November 9th, 2021 providing heat to the entire city of Haiyang with residents totaling about 200,000 people.

  With nuclear energy for heat application, Haiyang is now becoming China¨s first Net Zero Emission heating city. The plant has now the capacity to provide heating to about 4,500,000 square meters. Meanwhile, the rate has been lowered by one Yuan RMB (about 0.16US$) per square meter compared to previous years.

  Since operation of this project, the Unit 1# of Haiyang Nuclear Power has become the world¨s largest cogeneration unit, replacing 12 local coal-fired boilers. It is expected to avoid the use of 100,000 tons of coal by reducing emission of 180,000 tons of carbon dioxide, 691 tons of smoke dust, 1,123 tons of nitrogen oxides, and 1,188 tons of sulfur dioxide during every heating season, which is equivalent to plant 1,000 hectares of broad-leaved forests reducing heat emission to the environment by 1,300,000 GJ. This nuclear heating project will effectively improve the atmospheric environment and marine ecological environment during the regional heating season.

  The cogeneration of nuclear power plant mainly extracts non-radioactive steam from the secondary circuit, which is then fed through a multi-stage heat exchanger in an on-site heat exchange station. This heat is then fed to an off-site heat exchange station through the municipal heating pipe network to the local residents.

  China announced that it would aim to achieve peak CO2 emissions before 2030 and carbon neutrality before 2060. The Chinese government has made clean-energy heating a priority. The National Energy Administration released a five-year plan, covering 2017-2021, that highlighted clean heating technology. Shandong Nuclear Power Company will actively explore district heating for a larger scale, higher efficiency and longer distance.
