The closure of Hunterston B will not cause power network outages, Scotland’s energy minister Paul Wheelhouse has insisted. The nuclear power station is to close by January 2022, according to operator EDF Energy, almost two years earlier than expected. Last year, Scottish Gas owner Centrica blamed interruption of electricity supply from Hunterston for loss of income. Wheelhouse reiterated the Scottish Government’s position that no new nuclear power stations should be built in Scotland, with energy generated by renewable sources instead. He said that for a two-month period in 2018, Hunterston B was entirely offline and the Torness nuclear power station in East Lothian was operating at reduced capacity, but it caused no issues for the energy supply. Wheelhouse told the BBC: “Scotland, in the last year for which we got full statistics, exported a net 15.9 terawatt hours of energy – which dwarfs the output of Hunterston.” When challenged on the use of intermittent power – such as wind or solar, which can see outputs drop as conditions change – and the possibility of importing nuclear power from abroad, Wheelhouse said: “I’m not wanting to underplay the importance of Hunterston in the energy system.

Rob Edwards speaking about Hunterston. The lifetime of Hunterston has been extended 3 times. The problem is these very old reactors have developed all these cracks. Reactor 3 has an estimated 377 cracks. Reactor 4 has 209. Those are only estimates based on looking at a part of the core. They have underestimated the number of cracks that would appear in the past. If you have too many cracks you get bits of debris breaking off so the graphite core of these reactors start to crumble and that in some scenarios could cause the core to overheat. They are balancing how much money they can make out of the plants against a leak. Climate change has been used by the industry to try to make themselves look better. Hunterston has been closed for most of the last two years.
