The airspace over UK nuclear licensed sites is restricted by the Air Navigation (Restriction of Flying) (Nuclear Installations) regulations 2007. These impose restricted airspace of a radius between 0.5 and 2 miles to a height of between 1000 and 2400 feet around the centre of all nuclear sites. Airspace usage in the UK is regulated by the Civil Aviation Authority (CAA). Therefore it is a criminal offence to fly in the vicinity of nuclear sites without the permission of the CAA. The CAA and nuclear sites work closely together on this.
All of Britain’s nuclear power stations are robust and designed with safety in mind and are stress-tested to withstand a vast range of potential incidents. The independent regulator continuously monitors and evaluates the safety of each plant alongside the operator to protect it from outside threats.
