China's first power unit using the country's self-developed third-generation Hualong-1 technology has completed the very first phase of its commercial operation in Fuqing, southeast China's Fujian Province. The Hualong-1 is a Chinese Generation III pressurized water nuclear reactor jointly developed by the China General Nuclear Power Group and the China National Nuclear Corporation. The third-generation technology features with both active and passive safety measures to avoid potential accidents like what happened to the 2nd-generation units of the Fukushima power plant. Its designer says the unit's double-layer shell can withstand a magnitude-9.0 earthquake and even an air crash.
