Construction of the Tianwan Nuclear Power Plant Power Plant in east China’s Jiangsu Province, designed to provide process steam supply, kicked off the first such project in China on Friday. It marks an important step in diversifying the use of nuclear energy in China, in addition to electricity generation and residential heating.

The steam generated by the power plant will be supplied to the Lianyungang Petrochemical Industrial Base, one of seven petrochemical industrial bases planned in China’s coastal areas, according to a post on the Wechat account of China National Nuclear Power Co on Friday.

The project received an investment of 730 million yuan ($108.77 million) and a construction period of 24 months, and is expected to be put into production by the end of 2023. It is expected that the structure of the The seawater desalination plant and energy station will be completed by the end of this year.

The project will also establish an energy demonstration plan for the modernization and transformation of China’s petrochemical industry.

It is expected that upon completion of the project, it will be able to supply Lianyungang Petrochemical Industrial Base with 4.8 million tons of process steam per year, which is equivalent to reducing coal consumption by 400,000 tons or reduce carbon dioxide emissions by 1.07 million tonnes, sulfur dioxide by 184 tonnes and oxynitride by 263 tonnes.

The use of nuclear energy to produce process steam aims to meet the demand for steam in the petrochemical industry and is seen as a new way to reduce overall energy consumption and enhance environmental protection. environment. It usually extracts steam from a secondary circuit of a nuclear power plant as a thermal resource, and the heat is finally transmitted to the users’ unit through a process steam pipeline network after a multi-stage heating exchange.

Accelerating the overall use of nuclear energy is also an effective way to promote the transformation of low-carbon energy into clean heating and process steam supply in northern China, according to the post. .
