Bit of a research fail on my part, it was the Sellafield plant that went critical, while Barrow was hit by a 10 kilotonne nuke. Doesn't really matter though, now that I'm aware of the existance of Ground Zero II, I checked Barrow on there and Lancaster was in the clear, while Sellafield looks like it's far enough away to not be a major problem.
