One of the two cracked reactors at Hunterston B nuclear power station in North Ayrshire has been given permission to reopen – but only for four months. The UK Office for Nuclear Regulation (ONR) is allowing EDF Energy to restart reactor four, which has an estimated 209 cracks in its graphite core. It was shut down on 2 October 2018. ONR has accepted EDF’s argument that it’s safe to relax the limit for the permitted number of cracks. The “operational allowance” for cracks per reactor is being doubled from 350 to 700.
