UK’s ageing nuclear power stations are likely to close early

Fate of UK’s nuclear plants in doubt over ageing infrastructure, Guardian, Adam Vaughan, Energy correspondent @adamvaughan_uk, 4 Feb 2019 

After 12% drop in generation, experts say existing nuclear plants are likely to close early  Britain’s nuclear power stations recorded a 12% decline in their contributions to the country’s energy system over the past month, as outages raised concerns over how long the ageing plants will be able to keep operating.

A temporary closure of two of the country’s eight nuclear plants resulted in a double-digit drop in nuclear generation in January, compared to the same period last year.

Prospects for new nuclear projects have commanded headlines and government attention in recent weeks, with Hitachi and Toshiba scrapping their plans for major new plants.

But the fate of the existing plants, which usually provide about a fifth of the UK’s electricity supplies, has been pulled into focus by outages due to safety checks and engineering works running over schedule. Nuclear outages also push up carbon emissions because any capacity shortfall will typically be replaced by fossil fuel power stations

Seven of the power stations use an advanced gas reactor (AGR) design, the oldest of which is 43 years old and the youngest 30 years .

Most were built with a lifetime of about 35 years in mind. All are due to be closed in the 2020s after owner EDF Energy extended their lives, but there are now fears that ageing infrastructure may reduce their output or even lead them to shut early.

Iain Staffell, lecturer in sustainable energy at Imperial College, which compiled the nuclear output data, said: “Just as Toshiba and Hitachi have pulled out of building new reactors, we have one third of the existing nuclear capacity unavailable either for maintenance or because their maximum power has been reduced as they get older.

“Many of our reactors were built in the late 70s, and like your typical 40-year-old they aren’t in peak physical condition any more.”……… https://www.theguardian.com/environment/2019/feb/03/fate-of-uks-nuclear-power-stations-in-doubt-over-ageing-infrastructure
