– The world’s first generation IV nuclear power plant, jointly built by Shanghai Electric, enters commercial operation

SHANGHAI, Dec. 26, 2023/PRNewswire/ — The world’s first nuclear power plant project equipped with Gen IV nuclear power technology, the Shidaowan High Temperature Gas-Cooled Reactor (HTR) pebble bed module demonstration project -PM), of which Shanghai Electric is one of the main equipment suppliers, has entered into commercial operation, following the successful completion of 168 hours of testing that confirmed that all systems met the design functions. This milestone places China at the forefront of nuclear energy innovation as it continues to explore safe, reliable and sustainable energy sources to facilitate its goal of carbon neutrality and peak carbon.

The high-temperature gas-cooled reactor (HTGR), recognized worldwide as the fourth-generation nuclear power technology, which generates power through the conversion of nuclear, thermal, mechanical and electrical energy, is praised for its inherent safety and versatility, and It has immense potential. Potential for commercial applications as an alternative energy solution to fossil fuel-based energy sources.

Launched in 2006 and whose construction began in 2012, the Shidaowan HTR-PM demonstration project is one of the 16 major national science and technology projects, on par with China’s lunar exploration program and the development of the BeiDou navigation satellite system. .

Shanghai Electric, one of the key participants in the project, provided equipment including reactor pressure vessels, internal metal core parts, control rod drive mechanisms, shutdown systems, turbines, helium primary fans and helium compressors. . The completion of the plant marks the conclusion of a decade-long effort led by China’s leading energy solutions providers to overcome challenges in an effort to develop self-innovative solutions at the forefront of nuclear energy technology. 93.4 percent of the equipment used in the reactor is manufactured by Chinese companies.

The reactor pressure vessels, custom designed by Shanghai Electric for the project, feature larger sizes and more complex structures compared to their market counterparts, breaking industry records for height and weight. The metal inner cores manufactured for the project are the largest thin-walled metal inner cores in the world, a groundbreaking achievement that fills a gap in the China market. Leveraging its 20 years of experience, the company developed the world’s first high-temperature, high-pressure, high-power electromagnetic bearing primary helium fan.

HTGR is set to reshape the future of global nuclear energy development with its exceptional safety features. It ensures that the reactor remains safe even in the event of failure of all cooling systems, preventing core meltdown and leakage of radioactive material without any intervention. In a significant step for China’s nuclear energy security and nuclear technology innovation, the successful launch of the demonstration project greatly boosts China’s ability to lead the global nuclear energy sector, paving the way for future breakthroughs. in the generation of sustainable and safe energy.
