The party writes in a press release that electricity production needs to be doubled to cope with climate change and that nuclear power, together with solar and wind power, then plays a central role.

- This is great!

Sweden needs fossil-free electricity seven days a week.

Electricity we can trust for our welfare.

In addition, it is environmentally friendly as just that, says Reidar Svedahl (L) municipal councilor in Norrköping.

Small modular reactors, SMR, are nuclear power plants of up to 300 megawatts.

That's about a quarter of the power of a large reactor.

These "mini-reactors" can thus, like the reactors in today's large nuclear power plants, generate electricity from split nuclear fuel.

Heavy water reactor

Developers and advocates of SMRs emphasize that they are safer than larger reactors and also cost-effective, which could help to quickly build up nuclear power capacity for a reasonable amount of money.

However, researchers interviewed by SVT's science editorial staff believe that SMR can generate up to 30 times more radioactive waste.

Marviken would be the country's first large heavy water reactor.

But the power plant was never charged.

A few years ago, an archipelago town was planned there, but that investment ran out of steam.
