The French nuclear firm EDF Energy is applying for new authorisations to allow radioactive waste to be transported by road between its two nuclear power stations at Hunterston in North Ayrshire and Torness in East Lothian.
Critics say this will mean waste containers will be increasingly moved between the west and east coasts, increasing the risk of accidents.
Pete Roche, an energy consultant and former government radiation adviser based in Edinburgh, warned: “Transporting nuclear waste is always going to be a risk, so the more you transport it, the greater the danger.
“The Scottish Government should force EDF Energy to operate according to its sensible policy of requiring waste to be treated as near to where it is produced as possible instead of allowing this crazy plan putting the central belt of Scotland at risk.”
He described the plan as a “nightmare vision with waste trucks criss-crossing the country”.
