China continues to stake its claim as the world’s biggest proponent of new nuclear energy technology, connecting its first small modular reactor to the power grid.

China Huaneng Group Co.’s 200-megawatt unit 1 reactor at Shidao Bay is now feeding power to the grid in Shandong province, the China Nuclear Energy Association said in a WeChat post. A second reactor is undergoing tests before being connected and putting the plant into full commercial operations in the middle of next year.

The plant is the world’s first pebble-bed modular high-temperature gas-cooled reactor, heating up helium instead of water to produce power. It’s a so-called fourth generation reactor, designed to shut down passively if something goes wrong — in contrast to active systems that may not be able to trigger safety measures if power fails, which is what happened at the Fukushima Daiichi accident in Japan a decade ago.
