OREANDA-NEWS. August 7, 2007. Atomstroyexport has started the final stage of the commissioning of unit 2 of Tianwan NPP.

Specialists of Atomstroyexport SJC, jointly with their Chinese colleagues, have completed the preventive repairs of unit 2 of Tianwan NPP. During the repairs they tested the turbine set and the auxiliary systems of the machine compartment.

On Aug 3 2007 they synchronized and switched on the generator of the unit. The capacity of the reactor has been raised to 100%. Now the unit will be subjected to dynamic testing in line with the commissioning program: the main circulation and feed pumps will be turned off and the unit will be switched to self-sufficient capacity.

After the dynamic testing, ASE will start preparing the unit for commercial service — supposedly in Sept 2007.

As of today, Aug 7, unit 2 of Tianwan NPP has generated a total of 607,017 MWh.

Note

The contract for Tianwan NPP construction was signed in 1997. Under the contract, Russia is obliged to build two WWER-1000 power units with a total capacity of 2000 MW. This is the biggest Russian-Chinese project. Tianwan is the most powerful NPP project in China. 

The WWER-1000 reactors of Tianwan are safe and efficient. They have deeply echeloned protection with passive and active safety systems. The 1st unit was commissioned in May 2007.
