Nuclear convoys pass through Berwickshire up to eight times a year on their way to the Royal Naval base at Coulport on Loch Long, according to pressure group Nukewatch UK.
However, there is no local plan to deal with emergencies that may arise en route.
At a recent Scottish Borders Council meeting, Councillor Kevin Drum asked: “Can I ask the executive member if Scottish Borders Council has carried out a risk assessment in relation to the risks introduced to our roads by nuclear weapons convoys, when they pass through the Borders on route to Coulport, and have we communicated these risks and associated control measures with local residents and businesses in these communities?”
He was told that responsibility for transportation of nuclear warheads lies with the UK Government in close co-operation with Police Scotland. Information about the convoys is not made public or shared with local authorities and Scottish Borders Council complies with the Civil Contingencies Act 2004 and, as a category one responder.
