China to fire up small test nuclear reactor to heat smog-prone north
- Compact plants proposed to ease pollution but backers must win over wary public
China plans to build a pilot small-scale nuclear reactor that could replace coal or gas to heat towns and cities in its colder northern regions, an official with the state-owned developer in charge of the project said on Monday.
The small heating reactor was planned for the city of Jiamusi in northeastern Heilongjiang province, one of two proposed units with a combined capacity of 400 megawatts, Wang Xujia, a senior engineer with the State Power Investment Corp, said on the sidelines of an industry conference.
“The project is still under central government review for approval,” Wang said, adding that the developer aimed to put the project into operation by 2024.
China has been exploring the use of small nuclear reactors – less than a fifth of the size of a standard reactor – as alternative heating systems in smog-prone northern regions. The state provides heating throughout northern China from November to March, using predominantly coal- or gas-fired boilers.
State-owned China National Nuclear Corp (CNNC) has already conducted trial runs for a “district heating reactor” (DHR) design, which it says can supply heat to 200,000 urban households.
The DHR model consists of a reactor core immersed in a water-filled tank. It is estimated to require investment of 1.5 billion yuan (US$217 million) and take three years to build, making it cheaper and quicker to construct than conventional reactors.
