Hinkley Point B is an AGR (or, more specifically, two AGRs). Hinkley Point A was an earlier Magnox station.
It's one of the leading sites for new-build nuclear in the UK, and if Hinkley Point C does happen, it'll be a PWR. Right now, the only operating civil PWR (naval reactors are a rather different matter) in the UK is at Sizewell.
I also had the Hinkley Point tour as a child and remember it fondly.
