Wrong! If Scotland leaves the UK it would be the 2016 parliament that decides what could happen to Faslane and the 6000 Scots who work there. Although Trident is a hot topic within the SNP, there is no real evidence that Scots like/dislike it less than the rest of the UK. If the submarines were to leave, it could take decades and then the site would then have to be made safe at an "enormous" cost. But don't worry, anonymous sources within the SNP have said keeping "Trident on the Clyde will be price of keeping the pound".
When all this is happing Scotland will be seeking a site to store its long-term nuclear waste (from power plants the SNP Gov have used beyond their design life - "sweating").
