SHANGHAI — Shanghai Electric has announced the world’s first nuclear power plant project equipped with “Gen IV” nuclear power technology has been commissioned in Shandong province, China.
The Shidaowan demonstration project generates power through the conversion of nuclear, heat, mechanical and electricity power, stated a release. The technology is referred to as a High-Temperature Gas-Cooled Reactor Pebble-bed Module (HTR-PM). The plant entered commercial operation following the completion of 168 hours of a test run.
The project was initiated in 2006 and construction began in 2012. Shanghai Electric provided reactor pressure vessels, metallic core internals, control rod drive mechanisms, shutdown systems, turbines, primary helium fans and helium compressors.
The reactor pressure vessels come in larger sizes and more complex structures compared to their market counterparts, breaking industry records for height and weight, stated the release. The metallic core internals manufactured for the project are the world’s largest thin-walled metallic core internals.
The electrical firm also developed the world’s first high-temperature, high-pressure, high-power, electromagnetic-bearing primary helium fan.
Shanghai Electric says the project is also notable for its safety features. The HTR-PM technology ensures the reactor remains safe even in the case of the failure of all cooling systems, preventing core meltdown and radioactive material leakage without any intervention.
