Science and technology daily (CAI Pengfei, Liu Chuanshu) the reporter learned from China Guangdong nuclear power group that at 13:42 on May 2, with the issuance of the grid connection instruction, unit 6 of Liaoning Hongyanhe Nuclear Power Plant was successfully connected to the grid for the first time. This marks that unit 6 of Hongyanhe Nuclear Power Plant has power generation capacity and another key step towards the goal of commercial operation.

In the process of grid connection, the parameters of unit 6 of Hongyanhe Nuclear Power Plant are normal and stable, and the unit is in good condition. Subsequently, a series of tests will be carried out as planned to further verify that the unit has various performances under commercial operation conditions, and promote the high-quality operation of Hongyanhe Nuclear Power Unit 6.

As the first nuclear power plant and the largest energy investment project in Northeast China, Hongyanhe Nuclear Power Plant has built a total of 6 nuclear power units. Four units of phase I project have been completed and put into commercial operation in 2016; The construction of units 5 and 6 of phase II project was started in 2015, unit 5 was put into operation with high quality on schedule on July 31, 2021, and unit 6 is planned to be put into commercial operation within this year. 5. Unit 6 adopts acpr1000 technology of China Guangdong Nuclear Power Group, is equipped with three passive systems such as passive emergency high-level cooling water source system, and has implemented a number of technical improvements such as secondary side temporary water replenishment and mobile emergency power supply. It has the main technical characteristics of third-generation nuclear power, and the safety level has been further improved.

It is reported that Hongyanhe Nuclear power gives full play to the dual advantages of nuclear power as zero carbon energy and stable operation, and actively meets the demand of the power market. By the end of 2021, Hongyanhe Nuclear Power had accumulated 194.4 billion kwh of clean energy, equivalent to 59.11 million tons of standard coal consumption reduction, 163 million tons of carbon dioxide reduction, and 437800 hectares of forest absorption. It has played a positive role in revitalizing the old industrial base in Northeast China and adjusting the energy structure in Northeast China, and is of great significance to the implementation of the goals of carbon peak and carbon neutralization.
