The Guardian view on Labour’s nuclear bet: big promises, but bigger questions remain unanswered | Editorial

The UK government is committing £14.2bn to nuclear energy, signaling a major policy shift and a renewed focus on state-funded nuclear projects after cost overruns with privately financed ventures like Hinkley Point C. Ministers aim to complement renewable energy sources and accelerate the transition from gas, with the Sizewell C project expected to create 10,000 jobs. However, significant concerns remain regarding the high costs of nuclear energy compared to renewables, waste disposal, safety, and the potential for hidden subsidies to the military, raising questions about the overall strategy.

Analysis

The UK government's commitment of an additional £14.2bn to nuclear energy signifies a material shift in national energy policy, aiming to revive state-funded nuclear development after the privately financed Hinkley Point C project faced significant delays and cost overruns. This investment, which includes funding for the Sizewell C reactor, modular reactor development with Rolls-Royce SMR as a key player, and fusion research, is positioned as a complement to renewable energy initiatives to accelerate the transition from gas and is anticipated to generate substantial employment, such as 10,000 jobs at Sizewell C. However, this 'nuclear renaissance' is accompanied by considerable unresolved issues. The primary concern remains the high cost of nuclear power, which the article notes is far more expensive than wind energy (though wind costs are also rising), exemplified by Hinkley Point C's potential to double its original projected price. Persistent challenges of nuclear waste management, with current storage at Sellafield raising safety concerns and lacking a permanent solution, and general safety issues, are often downplayed. Furthermore, the article touches upon the potential for civil nuclear investments to provide indirect subsidies to the military and notes the burgeoning power demands from datacentres and AI businesses as a factor influencing the renewed interest in nuclear, a trend also observed internationally. The government's strategy requires greater transparency and detailed explanation, especially regarding how nuclear fits into a coherent net-zero plan that also prioritizes energy efficiency and robust green building regulations, contrasting with a previously 'lax approach to regulation'.

Key Decisions for Investors

• Investors should assess opportunities within the UK nuclear energy supply chain, particularly in companies involved with new reactor designs like Rolls-Royce SMR, while factoring in the substantial execution and timeline risks historically associated with large nuclear infrastructure projects.
• Closely monitor the UK government's project management capabilities and cost control measures for new nuclear developments, given the precedent of significant budget overruns at Hinkley Point C, and scrutinize plans for long-term nuclear waste disposal and safety assurance.
• Evaluate the evolving dynamics within the UK's broader energy transition portfolio, considering how increased nuclear investment will impact the growth trajectory and investment case for renewable energy sources and energy efficiency solutions.
• Consider the potential for increased baseload power demand from energy-intensive sectors like datacentres to support the long-term viability of nuclear power, but weigh this against the current cost competitiveness challenges and the unproven scalability of newer nuclear technologies like SMRs.
