China’s first project to provide industrial steam via nuclear power begins construction
我国首个工业用途核能供汽工程开工建设

Construction of energy station of Tianwan nuclear power plant, in East China’s Jiangsu Province, designed to provide an industrial steam supply, launched on Friday, the first-of-its-kind project in China. It marks an important step in the diversification of China’s nuclear power use, in addition to electricity generation and residential heating.

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

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

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

It is expected that once the project is completed, it will be able to supply to Lianyungang petrochemical industrial base 4.8 million tons of industrial steam a year, equivalent to reducing coal consumption by 400,000 tons or cutting carbon dioxide emission by 1.07 million tons, sulfur dioxide by 184 tons and oxynitride by 263 tons.

Using nuclear power to generate industrial steam supply aims to address steam demand in the petrochemical industry, and is regarded as a new way to reduce comprehensive energy consumption and strengthen environmental protection. It generally extracts steam from a secondary circuit of nuclear power plant unit as heat resource, and the heat is eventually transmitted to the users’ unit through industrial steam pipeline network after multi-stage heating exchange.

5月27日,第一罐混凝土在田湾核电蒸汽供能项目能源站正式浇筑,标志着全国首个工业用途核能供汽工程——中核集团田湾核电蒸汽供能项目全面开工建设。

核能供汽是利用核电厂热量,解决石化产业用汽需求,降低综合能耗和消除环境污染的一种新途径。

该项目建成后,每年可为连云港石化基地提供480万吨工业蒸汽,可实现每年减少燃烧标准煤40万吨,等效减排二氧化碳107万吨、二氧化硫184吨、氮氧化物263吨,相当于新增植树造林面积2900公顷。
