Nuclear bomb attack drills in Schools.

Sorry for the slightly alarmist title

My Sister in law who's 55 swears that they used to have nuclear attack drills when she was in School. My Wife and myself are 5 years younger and have no recollection of this during our school years.
Can any of you oldies ( ) confirm this and say when it stopped?

She's from Oxford but maybe she heard this and that was what made her mention it.
. Maybe they were a bit more pessimistic around those parts in late 60s?
