Scientists are excited about a test nuclear power plant that could be used as a fuel in China. Although this radioactive substance has been tested in reactors in the past, experts say that China is leading the way in marketing the technology.
The reactor is unusual because it contains salts that dissolve rather than water. It has the capacity to produce relatively safe and inexpensive nuclear energy, and it emits much longer radioactive waste than conventional power plants.
Construction of a test thorium reactor in Wuway, on the shores of the Gobi Desert, will be completed by the end of August – the Gansu state government said.
Torium is a weak radioactive, naturally occurring metal found in stone, and currently has little industrial use. It is a waste product of China’s underground mining industry, so it is an attractive alternative to imported uranium, say researchers.
“Because uranium is so abundant in uranium, it will be the most important technology in 50 or 100 years,” said Linden Edwards, a nuclear engineer in Australia. Organization in Sydney. But it will take decades to realize the technology, so we have to start now, he said.
According to Ritsu Yoshiyoka, president of the International Territory Molton-Salt Forum, which has worked closely with Chinese researchers, China has invested about 3 billion yuan ($ 500 million) in 2011.
The Wuway reactor, operated by the Shanghai Institute of Applied Physics (SINAP), is designed to generate only 2 megawatts of heat, enough to power up to 1,000 homes. But if the experiments succeed, China hopes to build 373 megawatts of power by 2030, which could power hundreds of thousands of homes.
Energy Modeling Jiang Kejuun, an energy research institute at the National Development and Rehabilitation Commission in Beijing, is one of the “perfect technologies” to achieve China’s zero carbon emissions target by 2050.
The natural isotope cannot produce torreium-232 flux, but when it is ignited in a reactor, it absorbs neutrons and produces uranium-233, a physical material that generates heat.
Torium has been tested as a fuel for other nuclear power plants in other countries, including the United States, Germany, and the United Kingdom, and is part of a nuclear program in India. However, it has not yet proved cost-effective because it is more expensive to produce than uranium and, unlike some naturally occurring uranium isotopes, needs to be converted into physical materials.
Some researchers favor tortoise as a fuel because the waste products are less likely to contain uranium than others, while others argue that there are still risks.
From the last explosion
Oak Ridge National Laboratory in Tennessee will be the first smelter reactor to operate in China since 1969, when US researchers shut down them. And it will be the first molten salt reactor to burn in torment. Researchers in collaboration with SINAP say Chinese design makes copies of Oak Ridge, but has improved innovation by calling for innovation in manufacturing, materials, and equipment for decades.
Researchers in China who were directly involved with the reactor did not respond to a question about when the reactor design confirmation and validation would begin.
Compared to conventional nuclear power plants, smelter generators operate at higher temperatures, which means they can generate electricity more efficiently, said Charles Forsburgh, a nuclear engineer at the Massachusetts Institute of Technology in Cambridge.
The Chinese reactor uses fluoride-based salts that dissolve in colorless and clear liquids when heated to 450 ºC. Salt acts as a cooling medium to transport heat from the reactor’s core. In addition, instead of solid fuel rods, molten-salt stimuli also use liquid salt to melt directly into the core as a substitute for fuels such as turmeric.
Melt-salt processors are considered relatively safe because the fuel is already depleted in the liquid and operates at a lower pressure than conventional nuclear power plants, reducing the risk of explosion.
Yoshiyoka Many countries are working on smelter refineries: to produce cheap electricity from uranium or to use waste plutonium from light water processors – but only China is trying to use turmeric.
Next Generation Reactors
“It will be a test bed to learn a lot,” says Forrsberg, analyzing rust to determine the composition of a radioactive compound during dispersal.
“We are learning a lot of new science,” agrees Simon Middleberg, a nuclear material scientist at Bangor University in the United Kingdom. If they let me, I would be on the first plane there.
The Chinese reactor may take months to complete the operation. “If something goes wrong, you can’t go on, and you have to stop and start again,” says Middberg. For example, the pumps may fall, the pipes may break, or the blockage may occur. Nevertheless, scientists hope for success.
Melt-salt reactor is one of the many nuclear technologies China has invested in. A.D. In 2002, six promising Rector technologies were identified to accelerate a government forum by 2030. China has all programs.
David Fishman, project manager at the Lanta Group Energy Consultant in Hong Kong, said that some of these reacters could be replaced by coal-fired power plants. “When China moves towards carbon neutrality, it can exit [power plant] Replace heaters and nuclear power plants. ”
