The first of four reactors being built at the Hongyanhe plant in Liaoning province in northeast China has begun commercial operation to become China's seventeenth operating nuclear power unit. The 1080MWe Chinese-designed pressurised water reactor officially entered commercial operation on 6 June after completing commissioning tests. The unit is said to be capable of supplying about one-quarter of the electricity demand of nearby Dalian City. Hongyanhe 1 is the first of four CPR-1000 reactors currently being built at Hongyanhe, and construction started in August 2007. Cold testing of the nuclear island of the unit was successfully completed in October 2012 and it achieved first criticality on 16 January. The unit was connected to the grid on 17 February.
