EDF is contemplating prolonging the lifespan of four of its nuclear reactors as part of the UK’s strategy to bolster its energy security.
The company oversees eight nuclear power station sites in the UK, out of which only five are currently active, while three are in the process of defuelling.
By the end of 2026, the existing group of five reactors is expected to be reduced to just three. Last year, the production levels dropped to their lowest in over 40 years.
The company’s leadership is now assessing the feasibility of extending the operational life of its four advanced gas-cooled reactors (AGRs) at Hartlepool and Heysham 1, which are set to close in 2026, as well as Heysham 2 and Torness, slated to operate until March 2028.
EDF has stated, “We will reevaluate these AGR lifetimes by the end of 2024, with the goal of continuing operation beyond the current projections.”
Additionally, EDF is considering a 20-year extension for the Sizewell B reactor, potentially from 2035 to 2055. A final decision on this is expected in 2025.
