China working on uranium-free nuclear plants in attempt to combat smog
China is developing a new design of nuclear power plant in an attempt to reduce its reliance on coal and to cut air pollution.
In an effort to reduce the number of coal-fired plants, the Chinese government has brought forward by 15 years the deadline to develop a nuclear power plant using the radioactive element thorium instead of uranium.
A team of researchers in Shanghai has now been told it has 10 instead of 25 years to develop the world’s first such plant.
“In the past, the government was interested in nuclear power because of the energy shortage. Now, they are more interested because of smog,” Professor Li Zhong, a scientist working on the project, told the Hong Kong-based South China Morning Post.
An advanced research centre was set up in January by the Chinese Academy of Sciences with the aim of developing an industrial reactor using thorium molten salt technology, the newspaper reported.
According to the World Nuclear Association (WNA), China has 20 nuclear plants in operation and another 28 under construction, all uranium-fuelled reactors. China has been importing large quantities of uranium as it attempts to reduce its reliance on fossil fuels. However, according to the WNA, thorium is much more abundant.
The researchers on the project said they had come under considerable pressure from the government for it to be successful. Li said nuclear power was the “only solution” to replace coal, and thorium “carries much hope”.
“The problem of coal has become clear,” he said: “if the average energy consumption per person doubles, this country will be choked to death by polluted air.”
“China has an ambitious nuclear-generation programme. It plans to have almost 60 gigawatts of nuclear energy by 2020 and up to 150gw by 2030, so the Chinese have plans to get a significant amount of nuclear into the energy mix,” said Jonathan Cobb of the WNA.
There is a lot that is still unknown about thorium but a lot of research is being carried out worldwide. Cobb said: “Other countries around the world are looking at thorium. There is a fair bit of research going on at the moment into the use of thorium. And technology-wise, using thorium would not be too much of a leap. It is certainly something that is well under way in terms of research,” said Cobb.
The researchers on the project told the South China Morning Post their work would be likely to face some opposition from Chinese citizens after the nuclear disaster at Fukushima, in Japan.
However, the national nuclear safety administration said the safety of China’s nuclear power plants could be assured, and checks had been stepped up since Fukushima to avoid a similar accident.
