How do mate?
To get you're magnox clearance you need to be put through by a company doing the nuclear work. You could've got the application forms from Larv, but unless capes are actually looking for men you probably won't get cleared. I did it all last year for Sizewell & Hinckley point, I took all the paper work & ID into the donny office & chased it up for weeks but got nothing from it.
I know a few lads who are off to dungeness for Hertel & they're only getting cleared becouse the manager wants them there.
You're probably better off trying to get your PTS card mate. Seems to be a fair bit of work with that ticket knocking about.
