[Unit 3 of Huaneng Changjiang Nuclear Power Phase II Project was put into operation and generated electricity] On September 17th, Unit 3 of Huaneng Changjiang Nuclear Power Phase II Project was put into operation and generated electricity on September 17. This is the first large-scale pressurized water reactor nuclear power unit built by China Huaneng Holdings and the first "Hualong One" nuclear power unit put into operation in Hainan Province. Huaneng Changjiang Nuclear Power Phase II project plans to build two 1.2 million kilowatt nuclear power units, which is currently the largest power project in Hainan. The unit is equipped with China's "Hualong One" third-generation pressurized water reactor nuclear power technology with completely independent intellectual property rights. It adopts a safety design concept that combines active and passive components, which significantly improves the operational reliability and safety level of nuclear power plants.
