UK launches radical overhaul of nuclear regulation system

The United Kingdom may undertake a sweeping reform of its nuclear regulatory system, deemed too complex and costly by an independent taskforce commissioned by the Prime Minister. In its final report, published on 24 November, the Nuclear Regulatory Taskforce calls for a “radical reset” to speed up delivery of nuclear projects in both the civilian and defence sectors, while maintaining safety standards.

Overcomplex regulation weighs on a strategic sector

The report identifies bureaucratic complexity as a major barrier to the competitiveness of the UK nuclear industry. It states that this complexity has contributed to the country’s relative decline in the sector, despite a pioneering history. The UK once had more operational reactors than the United States, the Soviet Union and France combined, but now lags behind in terms of speed, cost and innovation capacity.

The report puts forward 47 recommendations to streamline processes, including the creation of a centralised authority, the Commission for Nuclear Regulation, that would bring together all current decision-making bodies. Proposals also include merging the Defence Nuclear Safety Regulator into the Office for Nuclear Regulation (ONR), and adopting proportionality standards aligned with current international norms.

Estimated savings of tens of billions

The taskforce estimates that the reforms could generate savings of tens of billions of pounds in nuclear decommissioning costs, currently estimated at £150bn ($187.5bn). They could also reduce electricity costs for consumers and businesses, while accelerating the deployment of new-generation nuclear technologies, such as small modular reactors (SMRs).

According to taskforce chair John Fingleton, “the problems are systemic”, rooted in a process-driven rather than outcome-driven approach. He considers the reforms necessary to enable fast, safe and cost-effective expansion of the UK’s nuclear capacity.

Government support expected in upcoming Budget

The Chancellor of the Exchequer is expected to welcome the proposals in his upcoming Budget statement. Secretary of State for Energy Security and Net Zero, Ed Miliband, stated that the reforms are essential to achieving energy sovereignty. Minister for Defence Readiness and Industry, Luke Pollard, highlighted that nuclear remains a national priority for both defence and industry.

Industry leaders, including representatives from Sizewell C and Holtec International, expressed support for the recommendations, calling for a cultural shift in how energy infrastructure projects are designed and regulated in the UK. The ONR confirmed it is ready to incorporate the recommendations into its new strategy, which will be released for public consultation.

Expected impact on competitiveness and investment

The report anticipates a boost in private investment in the nuclear sector, along with improved national economic productivity. Clarifying rules, reducing approval times and better coordination among decision-makers could restore the UK’s credibility among investors and industrial partners.

With swift adoption of these reforms, the UK aims to reaffirm its position in the global nuclear landscape, combining safety, innovation and competitiveness.
