On fusion liability, Energy Minister completely sidelines the issue.

NFLA 27th Aug 2025

NFLA Secretary Richard Outram is disappointed that the new Energy Minister has completely missed the point that taxpayers should not be on the hook for unlimited liabilities to the nuclear fusion industry ‘resulting from incidents involving nuclear matter or emissions of ionising radiation arising from fusion activities relating to the STEP programme’.

On July 21, Climate Minister Kerry McCarthy issued a Departmental Minute to Parliament indicating that the Government will assume these liabilities for STEP (the Spherical Tokamak for Energy Production) project, the fusion experimental plant being built on a former power station site in West Burton with taxpayer money.

Richard wrote to his MP, Debbie Abrahams protesting that ‘As a citizen, I do not want my future taxes in hoc to a private company whose insurance risk for its nuclear activities would reside 100% with the future taxpayer. The procedure is certainly experimental; it may also be risky’. He asked that a request be placed with the Minister ‘with a full published risk analysis for STEP’ prior to a Parliamentary debate and vote.

In response, Ms Abrahams advised Richard that she had written to ‘the Department for Energy Security and Net Zero to make further enquiries about the STEP programme and make representations about your concerns’.

Ms McCarthy has now written back with a standard response in which she waxes lyrical about the supposed benefits that will be delivered through nuclear fusion, yet this is a technology described in the minister’s response as ‘nascent’, a euphemism for currently non-functioning.

The Minister makes a summary assessment that the risk presented by fusion is low, yet concedes ‘there is no private insurance market to provide cover to UKIFS (UK Industrial Fusion Limited) or their industry partners for liabilities in the unlikely event that radiological material or radiation is released from STEP outside of permit conditions‘.

This could suggest that the private sector might not want to insure any emerging nuclear fusion market because of the risk it presents, and if this is the case His Majesty’s Government might ultimately also have to indemnify nuclear fusion operators other than STEP in the future.

The Ministerial Direction effectively saddles the British taxpayer with responsibility to indemnify UKIFS ‘for an unlimited amount of money, for an unlimited time’.

And there is ambiguity in the timescale as some sources suggest STEP will be operational by 2040, whilst the Minister’s statement of 21 July says ‘by the 2040s’. This could mean 2049.

Finally, Richard was gratified to hear that the Minister’s letter was made in response to ‘a number of constituents’ suggesting some level of public disquiet with the Government’s decision………………………………………………………………………………………………………………………. https://www.nuclearpolicy.info/news/on-fusion-liability-energy-minister-completely-sidelines-the-issue/
