China's first commercial small modular nuclear reactor, Linglong-1, is now in the final installation phase.

Located in Hainan Province at the Hainan Nuclear Power Co. Ltd. (HNPC) site, Linglong-1 is being developed by the China National Nuclear Corporation (CNNC).

According to China's state-run Global Times, it is the world's first land-based small modular reactor (SMR) to begin construction, and it is expected to play a key role in reducing China's carbon emissions.

World's first commercial mini nuclear reactor
Linglong-1, also known as ACP100, is a third-generation small pressurized water reactor.

It was fully developed in China and has independent intellectual property rights. In 2016, it became the first SMR in the world to pass a safety review by the International Atomic Energy Agency (IAEA).

Because of its size and ability to deliver power safely and steadily, it has been called a "nuclear power bank."

Global Times reported that the reactor is part of China's 14th Five-Year Plan (2021–2025), focusing on advanced nuclear technology.

According to HNPC, the project is moving ahead as planned. Engineers are carrying out system tests, and preparations are made for cold functional testing, an important step before starting full operations.

Small modular reactors like Linglong-1 are different from traditional nuclear power plants.

They are smaller, safer, and quicker to build. These reactors use passive safety systems, which means they can shut down safely without human action or power.

Their smaller size allows them to be used in many locations, including industrial parks, mining areas, and regions that use much energy.

To power 526,000 homes
Each Linglong-1 reactor can produce 125,000 kilowatts of electricity.

That adds up to 1 billion kilowatt-hours annually, enough to power about 526,000 homes or around 1 million people.

By replacing coal-based power with nuclear energy from Linglong-1, China can reduce carbon dioxide emissions by about 880,000 tons every year. This is equal to planting 7.5 million trees.

CNNC says Linglong-1 fills a gap in China's nuclear development and shows that the country can lead in small reactor technology.

After the success of Hualong One, a full-size third-generation nuclear reactor, Linglong-1 is the next step in China's goal to innovate independently in nuclear energy.

The reactor is expected to help power the Hainan Free Trade Port and support clean energy goals in the region.

It will also help China meet its national climate targets, including reaching peak carbon emissions before 2030 and becoming carbon neutral before 2060.

Modular reactors like Linglong-1 could be useful in many countries, especially those looking for clean and stable energy sources without the' high cost and size of traditional nuclear plants.

The smaller design also makes building and operating reactors easier in areas with less infrastructure.

Once completed, Linglong-1 will become a key part of China's energy system, showing how nuclear technology can be used safely and efficiently to fight climate change.

It may also help China become a major exporter of small modular reactor technology in the future.
