How could a nuclear power plant be built in a factory?

Hook

Why and how could a nuclear power plant be built in a factory? It's called a small modular reactor, and countries from China to the United States are racing to build them.

Big

A traditional nuclear plant makes a thousand megawatts or more. It's custom built on site, and it often takes a decade or longer to finish.

Small

A small modular reactor makes up to about three hundred megawatts. That's a fraction of a big plant, but still enough for tens of thousands of homes.

Heat

Inside, it works like other nuclear plants. Uranium atoms split and release heat. That heat makes steam, and the steam spins a turbine that generates electricity.

Factory

The big idea is the factory. Major parts are built on an assembly line and shipped to the site. More modules can be added as demand grows.

Safety

Many designs use passive safety. If power is lost, natural forces like gravity and circulating water are designed to keep the core cool, without pumps or operators.

Catch

The catch is cost. China's first commercial one, Linglong One, has faced delays and reportedly costs more per kilowatt than a big reactor. Mass production is supposed to fix that.

Close

So a small modular reactor is a mini nuclear plant built like a product, not a giant project. ThatsWhyHow.
