There's not much information about the design itself, even on the SMR specific website (https://www.rolls-royce-smr.com). The best I could find was blurry embedded graphic with cross section of what looked like a reactor vessel.

There's some pretty detailed information in the GDA documents on the site:

How did I miss the big GDA link at the top of the page? Thanks!
