MOSCOW, July 16 (RIA Novosti) - The second unit of a Chinese nuclear power plant being built by Russians has been suspended for 22 days for planned maintenance, Russia's nuclear equipment export monopoly said.

Atomstroyexport is building the Tianwan plant in eastern China's port city of Lianyungang under a 1992 agreement. The plant features improved VVER-1000 reactors and K-100-6/3000 turbo generators.

Russia had planned to commission the second reactor in September. The unit, which was tested at 100% capacity last week, will undergo planned maintenance and then be re-tested. Commercial operation of the reactor may begin on schedule in September, Atomstroyexport said.

The second reactor has produced 567,979 MW/h of power since early May.

The first unit was completely commissioned in early June, and experts are preparing a feasibility study for the third and fourth units.
