Chapter 1: The Russian Nuclear Dependency

The UK is actively seeking to diminish its reliance on nuclear fuel from Russia, a vital step amid ongoing geopolitical tensions. One of Putin's most significant tactics in his campaign against Ukraine has been leveraging Russia's energy dominance. Since the dissolution of the USSR, Western nations, including Europe and the US, have increasingly depended on inexpensive Russian energy supplies. This reliance has made it easier for Putin to threaten to halt energy shipments to stymie support for Ukraine.

However, this dependence extends beyond oil and gas; it also encompasses Russia's intricate nuclear fuel industry, which poses a greater challenge for the West to replace. Fortunately, the UK is initiating measures to counteract this reliance, but the question remains—will these efforts be timely?

The extent of the UK's reliance on Russian nuclear fuel may come as a surprise.

Nuclear fuel is not just raw uranium; it requires enrichment. This complex process enhances the concentration of U235, the isotope responsible for nuclear fission, which generates nuclear power. The machinery necessary for enrichment is prohibitively expensive and time-consuming to construct, making it a formidable barrier for nations looking to develop their own capabilities.

Although uranium is sourced globally, Russia currently dominates the enrichment market, holding 43% of global capacity. This situation arose after the Soviet Union's collapse, which left behind a plethora of enrichment facilities. These plants have been more cost-effective to operate than those in the West, leading to a gradual closure of domestic facilities and a growing dependence on Russian services.

As a result, the current situation is alarming: 20% of the US's nuclear fuel is sourced from Russia, costing the US a staggering $100 million each month to Rosatom, the Russian state nuclear corporation. Despite sanctions, the EU spent $720 million on Russian-enriched uranium in 2022, a 22% increase from the previous year. While exact figures for the UK remain unclear, officials have acknowledged a concerning reliance on Russian fuel.

In light of the ongoing conflict in Ukraine, this dependence raises significant concerns. Not only does it provide Putin with leverage to pressure the West, but all profits from this state-owned industry ultimately fund his military endeavors.

France was the first to recognize this vulnerability and has taken steps to rectify it. The French company Orano has approved a €1.7 billion expansion to boost its enrichment capacity by 30%, aiming to reduce its dependency on Russian fuel. However, this new capacity won't be operational until 2028.

In response, the UK has announced a £300 million investment to enhance its enrichment capabilities. The new fuel being developed is known as High-Assay Low-Enrichment (HALEU) fuel. This type of fuel can be utilized in standard nuclear reactors but is essential for next-generation reactors such as Small Modular Reactors (SMRs) and fast reactors, which require higher concentrations of U235. Until recently, HALEU was predominantly sourced from Russia, making this development particularly significant.

The UK will be the first European nation to manufacture advanced nuclear fuel. HALEU offers several advantages over traditional nuclear fuel, including longer intervals between refueling, reduced nuclear waste, and cleaner byproducts.

Nevertheless, much like France's initiative, this solution is not immediate; the new enrichment facilities won't start producing fuel until the 2030s. The overall cost and output of this project remain uncertain, meaning the UK will still rely on Russian fuel for the foreseeable future.

Despite these challenges, the UK's HALEU initiative represents a substantial step forward. At COP28, the UK joined over 20 nations, including the US, France, and South Korea, in a commitment to triple global nuclear capacity by 2050, all part of their strategy to lower carbon emissions. Nuclear power boasts one of the lowest carbon footprints among energy sources, producing only about 4 grams of CO2 per kWh. It also has a remarkably low fatality rate compared to other energy sources, with 90 deaths per 1,000 terawatt-hours, significantly lower than coal.

This push for HALEU enrichment is a crucial move toward fulfilling the ambitious pledge and could profoundly impact global efforts to combat climate change while simultaneously reducing Putin's influence over Europe.
