This is a 10th Generation Boiling Water Reactor. Here's some relevant links:

Interesting point: no pumps; convection flow for 100% of the operational envelope.

The BWRX-300 footprint is so large they might as well just build large nuclear power units again and get 3-4x the power

Place your bets now.

Time until first power generated, and actual final total cost.

I’ll go 15 years and $10 Billion.
