Sorry to disillusion you, but how do you know that the UK send Vanguard subs to the South Atlantic?
Where any nation (UK, US, France, China or Russia) sends nuclear armed subs is usually very highly classified. No-one would announce where an SSBN would go, it defeats the logic of nuclear deterrence if you tell people where they are (particularly as they don't need to be anywhere near any country to threaten that country with Trident missiles). There is, as has been pointed out, a big difference between nuclear powered and nuclear armed. I am afraid you are simply wrong on this one.
