Atomstroyexport is building the Tianwan NPP in eastern China's port city of Lianyungang. The plant, which is being built under a 1992 bilateral agreement, features improved VVER-1000 reactors and K-100-6/3000 turbo-generators.
"The final dynamic testing of the first power unit was successful," the company said.
Atomstroyexport is currently preparing documents to put the unit into commercial operation, which the company said would take place in the near future.
The first unit of the Tianwan NPP went online in early January, but was then shut down for maintenance work. The second power unit of the Chinese nuclear power plant was put to 12% of its nominal capacity May 8.
Atomstroyexport is building seven NPP power units in China, India, Iran and Bulgaria.
