First concrete has been poured at China’s Tianwan NPP in Jiangsu Province for China’s first industrial-use nuclear energy steam supply project, China National Nuclear Corporation (CNNC) has announced. This followed three months of pile foundation construction. The steam will be utilised by the Lianyungang Petrochemical Industry Base.

The Tianwan Nuclear Power Steam Energy Supply Project uses the steam from units 3 and 4 of the Tianwan NPP as the heat source, and transports the steam to the Lianyungang Petrochemical Industrial Base for industrial production. The total investment in the project is CNY730 million ($109,5m), and the construction is expected to take 24 months. The project will provide 4.8 million tons of industrial steam for the Lianyungang Petrochemical Base every year, which can reduce the burning of standard coal by 400,000 tons a year

The construction planning and project design were reviewed by the General Electric Power Planning and Design Institute. The project started the construction of the pile foundation in February. To date the relocation of the meteorological tower and the environmental monitoring station, and the construction of all the pile foundations of the energy station have been completed successively, CNNC said.

Tianwan NPP comprises eight units. Units 1-4 (Phases I and II), which began commercial operation between June 2007 and December 2018, are Gidropress VVER-1000 units supplied by Russia. Phase III (units 5 & 6, are ACPR1000 reactors. Tianwan 5 began commercial operation in 2020 and unit 6 in 2021. Phase IV (unit 7&8) are under construction and will be Russian supplied VVER-1200 units.
