China's Groundbreaking Fourth-Generation Nuclear Reactor Powers Up

China's Shidaowan nuclear power plant, the world's first fourth-generation reactor, has begun commercial operations. The high temperature gas-cooled reactor (HTGR) uses helium gas instead of water for cooling, making it a promising option for inland nuclear plants. The reactor aims to be safer, more sustainable, and efficient, with the ability to produce heat, power, and hydrogen. Fourth-generation reactors are designed to limit environmental impact, nuclear waste, risk of meltdown, and opportunities for nuclear proliferation. China has been increasing its nuclear capacity, but nuclear power still only accounts for 5% of the country's energy generation.
