At 21:35 on June 23, with the successful completion of 168-hour Test Run, Unit 6 of Liaoning Hongyanhe Nuclear Power Station officially met the conditions for commercial operation, marking that a total of six units of Hongyanhe Nuclear Power Station Phase I and Phase II projects were fully put into operation, and became China’s in-service largest nuclear power station in terms of installed capacity.
Hongyanhe Nuclear Power Station is the first nuclear power station in Northeast China and the largest power energy investment project in Northeast China. The project has built a total of 6 gigawatt-level nuclear power units. Hongyanhe Nuclear Power Unit 6, which was put into operation today, started construction in July 2015 and was connected to the grid for the first time on May 2 this year. Subsequently, a series of commissioning tests were carried out, and the 168-hour continuous full power operation assessment was successfully completed.
Since the first unit was put into operation for power generation, Hongyanhe Nuclear Power Station has maintained continuous, stable and safe power supply. By the end of March this year, Hongyanhe Nuclear Power Station had accumulatively delivered 204.1 billion kwh of on-grid power. With Unit 6 being online， Hongyanhe Nuclear Power Station has become the largest nuclear power station in China and the third largest in the world, with a total installed capacity of more than 6.71 GW.
The annual generating capacity of the six units of Hongyanhe Nuclear Power Station can reach 48 billion kwh, accounting for about 20% of the total electricity consumption in Liaoning Province, compared with coal-fired power plants of the same scale, it is equivalent to reducing the consumption of standard coal by about 14.52 million tons, reducing emissions of carbon dioxide by about 39.93 million tons, equivalent to planting 108,000 hectares of forest.
