When I was in high school, I did a week's work experience in the computing department at Dounreay
We worked on the ground floor of the building that houses the old DFR control room (it was just upstairs from us). We were right in the shadow of the spherical reactor housing (affectionately known as "the Golf Ball".
They had all sorts of old tech in their computing department - DEC VAX systems, racks full of old Gandalf kit, etc. It was 16 years ago now, and I can't remember what else they had in there. There was also just about the biggest and noisiest line printer (used for printing payslips) in an adjoining room.
My mother also worked as a contracts officer on the Dounreay site for many years.
We lived in a nearby town called Thurso, which was a small fishing port prior to Dounreay's construction. The town literally doubled in size during the 1950s as construction on the Dounreay plant began. The UKAEA was Thurso's biggest employer. Since the plant stopped generating power (in the mid 1990s), the town has stagnated and the population has been gradually declining. There's nothing up there (employment-wise) to attract newcomers any more.
