Unit four of the Tianwan Nuclear Power Plant in China entered industrial operation this previous weekend after finishing commissioning. It started supplying energy to the nation’s nationwide grid on Dec. 22.
Tianwan NPP is the biggest facility constructed with a Russian-Chinese framework of financial cooperation, with Units 1 via four primarily based on the VVER-1000 reactor kind. Units 1 and a pair of entered industrial operation in 2007, and Rosatom handed over Unit three to Jiangsu Nuclear Power Corp. (JNPC) in March of this 12 months.
Tianwan Unit four was delivered to its minimal controllable energy degree on Sept. 30, marking the ultimate stage of first criticality procedures, which started Aug. 25 when the primary gas meeting was put in within the reactor. A complete of 163 gas assemblies have been in the end loaded.
Russia’s Atomstroyexport was common contractor for the mission, working with JNPC. Alexey Bannik, vp for tasks in China with Rosatom’s engineering division, mentioned the beginning of economic operation of Unit four “signifies that a two-year guarantee interval for the plant operation has commenced, and as soon as expired the Unit will in the end be handed over to the Chinese Party.”
Four More Units Planned at Tianwan
Construction of Units 5 and 6 at Tianwan continues, with these reactors scheduled to come back on-line over the following three years. Those two reactors are of the ACPR-1000 design. The first reactor using that design started industrial operation this previous summer time, at Unit 5 of the Yangjiang Nuclear Power Plant in Guangdong province.
Another two items, 7 and eight, are scheduled to be constructed at Tianwan underneath an settlement JNPC lately signed with Russia and Atomstroyexport. Those items will likely be third-generation VVER-1200 reactors, the identical know-how for 2 different new reactors additionally included in that deal, on the new Xudabao nuclear web site.
Shen Yanfeng, common supervisor of the China National Nuclear Corporation (CNNC), mentioned Units three and four at Tianwan, a part of what’s referred to as the Tianwan Phase II Project, “mixed will improve the electrical energy era to 16 to 18 billion kWh per 12 months.” Chinese officers mentioned that whereas the mission was inbuilt live performance with Russia, many of the plant’s tools has been made in China, together with the steam generator.
“The steam generator to the nuclear energy plant is just like the boiler to the facility plant, mentioned Zhang Yi, working director of CNNC. “A horizontal steam generator utilized in Russia’s know-how has bigger water storage than the vertical one in France or the U.S. You know, the bigger the storage, the safer the tools.”
Rosatom final week mentioned it’s getting ready contracts for the third and fourth energy items of on the Xudabao plant, in keeping with firm CEO Aleksei Likhachev. “VVER-1200 [reactors] will likely be contracted on the Xudabao facility because the third and fourth items,” Likhachev mentioned on Dec. 18. He mentioned “building work will likely be launched in coming months.”
