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.

Zooming in: Located in China’s Jiangsu province, Tianwan is co-owned (with Atomstroyexport) and operated by Jiangsu Nuclear Power Corporation, a joint venture of CNNC, Shanghai Hexi Power Investment, and Jiangsu Guoxin Group. The plant holds four Russian AES-91 PWRs (Units 1 and 2 began commercial operation in 2007, with Units 3 and 4 coming on line in 2018), plus Unit 5 and its twin, Unit 6, which is slated for commercial operation in 2021). In addition, the construction of two Russian VVER-1200 PWRs, Units 7 and 8, is scheduled to begin in 2021 and 2022, respectively, with completion in 2026 and 2027.

Our take: Anyone doubting the projections in yesterday’s story on China might want to reconsider.
