Construction Of SMR Underway In China

China National Nuclear Corporation (CNNC)' said construction of a multi-purpose small modular reactor (SMR) demonstration project had begun at the Changjiang Nuclear Power Plant in South China's Hainan Province.

CNNC's SMRConstruction began on July 13, CNNC said, noting, "This project became the world's first commercial onshore SMR to start construction, signaling that China is leading the world in terms of SMR technology."

It is also another major achievement made by CNNC in terms of forging a working relationship with the Hainan provincial government, CNNC said.

The. Linglong One reactor, also known as ACP100, is a multi-purpose pressurized water reactor (PWR) design developed by CNNC following more than 10 years of independent research and development. In 2016, the Linglong One design became the first SMR to pass a safety review by the International Atomic Energy Agency (IAEA).

Unlike traditional nuclear power technologies, SMR technology has such features as being small, modular, integrated, and passive. It is considered safer than a traditional, full-sized commercial reactor, quicker to build, and more flexible in deployment, SMRs can be used as clean distributed energy. They can also be used for seawater desalination, and heating or cooling, among other useful purposes. As an energy source, it's size also opens the technology up for electricity production for remote parks, islands, mining areas, and/or high energy-consuming enterprises.

Each Linglong One unit has a power generating capacity of 125,000 kilowatt (kW). After being completed, it will have an annual power generation capacity of 1 billion kilowatt hours (kWh), meeting the energy demands of 526,000 households.

This Changjiang SMR demonstration project is wholly owned by CNNC's China National Nuclear Power. Its construction will enable the implementation and verification of SMR technology and speed up the improvement of China's independent innovation capabilities in the field of SMRs. Potentially, the first SMR "lays the foundations for future large-scale" SMR deployment.
