Unit 3 of the Tianwan nuclear power plant in China’s Jiangsu province was connected to the grid on 30 December. The Russian-supplied VVER-1000 is scheduled to enter commercial operation later this year.
Tianwan 3 and 4 are AES-91 VVER-1000 units designed by Gidropress and supplied by Russian state nuclear company Rosatom. AtomStroyExport is the main contractor, supplying the nuclear island. First concrete for unit 3 was poured in December 2012, while construction of unit 4 began in September 2013. Two similar VVER-1000 reactors (units 1 and 2) began operating at the site in 2007.
The process to load a total of 163 fuel assemblies into the core of Tianwan 3 got under way on 18 August. The start-up process began on 27 September, with the reactor achieving criticality two days later.
