On March 22, 2023, Zhejiang Sanmen Nuclear Power Unit 4, a subsidiary of China National Nuclear Corporation, poured the first tank of concrete for the nuclear island, marking the beginning of the construction of the second phase of the Sanmen Nuclear Power Project. Since then, the number of nuclear power units under construction under China Nuclear Power Holdings has reached 9 units, with an installed capacity of 10.129 million kilowatts.

The second phase of Sanmen Nuclear Power Project is a national key energy project. After the two units are completed and put into operation, the total installed capacity of Sanmen Nuclear Power will reach 5 million kilowatts, and the annual power generation will reach 40 billion kwh, which is equivalent to an annual reduction of 30 million tons of carbon dioxide emissions. , will effectively promote the adjustment of industrial structure and energy structure in Zhejiang Province, and support the security of East China power grid and regional energy supply.

Nuclear power not only provides energy and power for economic development, but also integrates scientific and technological strength and manufacturing capabilities. The nuclear power industry is highly correlated and has a long industrial chain, involving dozens of upstream and downstream industries. The construction process not only promotes the improvement of localization capabilities through nuclear power equipment manufacturing, but also drives the development of a large number of related industries such as metallurgy, electromechanical, and manufacturing. Unit 4 of the Sanmen Nuclear Power Plant, which started construction this time, mainly relies on domestic forces for independent design, independent manufacturing, independent construction, and independent operation.
