Welcome to Zero. I am Akshatrati. This week, how big things become small.

Thank you. week, how big things become small. Among all forms of energy, the fastest growth is for electricity.

And that's making people look to every possible technology, including nuclear.

Last week, we talked about how the West has been struggling to build big nuclear power plants in recent decades.

Today, we'll talk about small modular reactors, what some say could be the solution to the problem. Don't build large, build

small. The idea is enticing. Take something that's big and hard to build and expensive, shrink

it down to something that's more manageable, easier to replicate, perhaps even cheaper. Instead of one

huge nuclear power plant, you build 10 small ones.

But right now, these kinds of small modular reactors are very much in the startup phase,

with only two in commercial operation, in Russia and in China.

There are hundreds of different designs vying to be the next success story, all with their own pros and cons.

And there are, of course, concerns about safety.

So how viable is the business for these small modular reactors?

Will SMRs ever become a scaled-up solution for our energy needs and climate goals.

This week on zero, I'm joined again by Rachel Slebaugh.

She's a partner focused on climate, sustainability, and energy at the venture capital firm,

TCVC, where she has made investments in startups that are shrinking nuclear reactors.
