Tianwan-5 ready for commercial operation
Unit 5 at the Tianwan nuclear power plant completed its full-power continuous operation assessment on September 8, meeting the conditions for commercial operation, China National Nuclear Corporation reported. The domestically designed ACPR-1000 pressurized water reactor will become CNNC’s 22nd reactor to provide power to China’s electric grid, raising the CNNC fleet’s installed capacity from 19.112 million kilowatts to 20.230 million, according to the company.
Tianwan-5 construction officially commenced on December 27, 2015, with the pouring of safety-related concrete. China’s National Nuclear Safety Administration issued a 40-year operating license for the unit on July 7 of this year, and two days later CNNC announced that first fuel loading had been completed. The reactor achieved initial criticality on July 27 and connected to the grid on August 8. Once commercial operation of the unit has begun, Tianwan will boast five operating reactors.
