The government’s apparent answer to climate change and Russia’s invasion of Ukraine is to triple the amount of nuclear generated electricity in the belief that it generates ‘low carbon’ electricity. But a recent admission by Prime Minister Rishi Sunak suggests there is a strong military component to what looks on the surface to be a civil matter.
The UK review of the energy sector, prompted by the invasion of Ukraine, offered a golden opportunity to address the need to drive down demand for electricity and energy more generally. This could be achieved by retrofitting insulation to the housing stock and buildings, mandating solar panel use for all new homes, investing heavily in renewables, in emerging battery technology and in decentralisation. Instead, the government has focused on a massive expansion of nuclear-generated electricity.
The dual nuclear agenda
Now the reason has finally been openly admitted. Maintaining and improving the supply chain and the knowledge and skills base in the workforce for the UK’s £100bn Trident nuclear weapons renewal programme relies on the civil nuclear sector.
While this claim has been regularly made by anti-nuclear campaigners – and just as regularly denied by minister after minister – it is now openly acknowledged. The Roadmap states quite clearly that it is important to align civil and military nuclear ambitions across government, to strengthen the interconnections between civil and military industries’ research and development, and thereby reduce costs for both the weapons and power sectors.
In March 2024, Prime Minister Rishi Sunak explicitly linked nuclear weapons production capability with civil nuclear power generation development. This is because nuclear reactors are used to create tritium – the radioactive isotope of hydrogen – necessary for nuclear weapons.
The cat which was so carefully and fraudulently hidden for decades is finally out of the bag: ministers now have to acknowledge that the civil nuclear programme owes more to maintaining weapons of mass destruction – weapons that were outlawed by the Treaty on the Prohibition of Nuclear Weapons which entered into force in January 2021 – than it has to do with salvation from the existential crisis that is climate change.
Debunking myths: the truth behind nuclear ambitions
Its brave new world aims for a nuclear sector generating upto 24 Gigawatts of electricity by 2050. That’s comparable to seven new 3.2 Gw capacity Hinkley Point Cs or Sizewell Cs or forty-eight Sizewell A-size reactors at around half a Megawatt output.
The locations for a proposed ‘mix’ of ‘gigawatt-sized reactors’ such as the European Pressurised Reactor (EPR) planned for Sizewell C, and ‘small modular’ and ‘advanced modular’ reactors (SMRs and AMRs respectively) is the subject of the government’s ‘Nuclear Road Map’.
It is, necessarily, largely a work of fiction laced with eulogies to nuclear power and liberally interspersed with admissions of hope over expectations. The truth is that Hinkley Point C is now expected to cost an eye-watering £40+bn from its original £20bn, and Sizewell C has already cost the taxpayer £2.4bn in sweeteners to the private sector.
Commercial SMRs don’t yet exist, and they are not small, unless you consider that Sizewell A falls into that category. AMRs have remained a fantasy for decades and are likely to remain so. Mention them to a nuclear regulator, and you’ll probably get a raised eyebrow in response.
Nuclear revival: promises vs reality
The Sizewell project has yet to be granted multiple construction and operating permits and licences and no final investment decision has been made. Other issues which make Sizewell C a terrible idea include:
- A multi-billion hole existing in its finances
- There is no reliable and guaranteed supply of potable water – of which an average of 2.2 million litres a day are required in the country’s most water-scarce area
- It is situated in a flood zone
- It is in an Area of Outstanding Natural Beauty
- It sits on the fastest-eroding coastline in northern Europe
- An estimated 46 hectares of woodland have already been flattened
- The Environment Agency (EA) has authorised the dumping of 1,590 tonnes of dead and dying fish back into the North Sea each year as a consequence of the Sizewell C cooling water intake (not to mention the 100s of millions of fish, fish larvae and other marine biota)
- In addition, there will be an estimated 171 million sacrificial sand goby, none of which are acknowledged by the EA.
- Radiological discharges from Sizewell C to the sea and air have contested health impacts
EDF ploughs on
The Supreme Court is still considering the merits of a judicial review appeal against the original planning approval. None of these uncertainties and deficiencies have stopped EDF devastating the areas around the development with the sanction of the local planning authority.
The tragedy is that nuclear is now a redundant technology which takes too long to come to our climate-change rescue and is not fit to be in the front-line of defence against climate change. It does not represent a plan of great urgency to meet the accelerating existential threats of climate change.
It has a rapidly narrowing window in which to contribute its electricity to the job of reducing climate change risks. When compared to renewables and conservation measures, nuclear is slow, costly and unreliable in terms of the new technology embodied in the EPR design. The Flamanville project in France, using a Sizewell EPR-type reactor, is still offline, is twelve years late and will cost four times the original budget.
The government has been in thrall to nuclear power for a long time. Perhaps with the admission of its connection to its strategic miliary goals, we can now better understand why that is. But the knowledge only deepens and entrenches the divide between the hawks and the doves.
