Safety Issues and Impact on Marine Environment of Extension of British Nuclear Plant Lifespan Queried by NGO

12th February 2025
In December 2024, EDF, the owner and operator of the plant declared a life extension of 1 year for Heysham 1 and of 2 years for Heysham 2 (pictured above) on the Irish Sea. They will now operate until 2027 and 2030 respectively.

The Celtic League NGO has queried the impact on the marine environment of the British government’s decision to extend the life of four old nuclear power plants.

It has also said that the decision is one that both the Irish and Manx governments should be concerned about, given the potential environmental impact.

Last month, French state-owned company EDF Energy said that the lifespan of Scotland's last remaining nuclear power station and three other plants in England would be extended.

The company said that Torness, in East Lothian, and its sister site Heysham 2, in Lancashire, would continue generating for an extra two years until 2030.

Two other sites - Hartlepool and Heysham 1 - will continue for an extra year until 2027, it said, and it planned to invest £1.3bn (sterling) across its operational nuclear estate over the next three years.

The Celtic League has noted that there was a previous review of a decision to extend Torness’s lifespan, after the discovery of cracks in the graphite bricks, which make up the reactor cores of some advanced gas-cooled power stations.

Bernard Moffatt of the Celtic League has submitted a number of questions relating to safety to British Chief Nuclear Inspector Mark Foy at the Office of Nuclear Regulation, and says it will publish any response it receives.
