The Office for Nuclear Regulation (ONR) has today provided EDF Energy Nuclear Generation Ltd (EDF NGL) with permission for Reactor 4 at Hunterston B power station to return to service for a limited period of operation. The permission is for operation up to a total of 16.25 terawatt days, which is approximately six months operation. ONR’s assessment focussed on whether cracking observed in the graphite bricks that form the reactor core of Reactor 4 could compromise its fundamental nuclear safety requirements.

I am pleased to confirm that the ONR has approved the return to service of Reactor 4 following a rigorous assessment of our safety case. I welcome the decision and preparations are underway on site to bring the reactor back online over the coming days. Having both reactors generating will mean that Hunterston B can do the important job of making low carbon electricity, helping to reduce reliance on gas-powered generation, until the site moves into defuelling. We have carried out detailed inspections and modelling of the reactor and the resulting safety case has been subject to extensive scrutiny and testing, by EDF and independently. We have been able to demonstrate that even in the most extreme conditions our reactors will safely shutdown, including in the event of an earthquake larger than ever experienced in the UK. Reactor 4 has been given permission to operate for a period of approximately six months. We plan to seek permission for a further run of six months for both reactors before generation ends no later than 7 January 2022.

Extract of Letter Elizabeth McLardy: Our worst unbelievable nightmare has just been confirmed. Contrary to all the concerns of individuals and numerous organisations, EDF and ONR have decided to ride roughshod over every one of us and fire up a defunct nuclear reactor that was shut down over two and a half years ago because it was unsafe to continue operating. Over that time, it most certainly will not have improved any – if anything it will have deteriorated. EDF have done more computer modelling, given more estimates and predictions and outrageously ONR have said no problem fire it up. The silence from the Scottish Government is deafening. All we have heard about is the loss of jobs (yet) there will be countless jobs for years to come, but astonishingly not a word about the real danger to millions of lives. (not on the web)
