Hi, I'm Hannah and I'm very excited to be hosting What in the World a new daily podcast from the BBC World Service, where we try to help you make sense of the world around you, of the big things that are happening, the small things that are happening and everything in between.

Just search for what in the world, wherever you get your BBC podcasts, and hit subscribe.

Today we are looking at nuclear energy and if it could be the answer to current and future energy worries.

For that, let me take you to the European country with the highest nuclear share in the world,

France.

Around 70% of its electricity is produced through nuclear power plants.

The country aims to prolong the lifespan of its 56 existing nuclear reactors and construct additional ones.

We are paving the way today for the nuclear renaissance of France.

Although not everybody feels comfortable with this energy source.

They tell us that they are implementing new safety measures,

but they are incapable of doing it.

We don't feel safe.

So how much sense does Francis nuclear strategy make, economically speaking?

Could the country lead the way?

But first, how does a nuclear reactor actually work?

Nuclear physicist Bernard Lepanch helped develop France's first nuclear reactors.

Since then, he became one of the country's most prominent opponents of nuclear energy.

In a coal power plant, you produce heat by burning coal.

In a nuclear reactor, what you call the nuclear vessel,

you produce heat by the fission of uranium, roughly.

And you heat water, which is circulating in the reactor.
