State of supply: uranium in Europe
Despite being a strategic commodity, uranium has maintained a relatively low profile in the news even as the war in Ukraine continues and Europe’s energy crisis unfolds. This is surprising considering nuclear power, which depends on uranium, contributes roughly 25% of the EU’s total electricity generation. Russia itself has long been a key supplier of uranium and nuclear fuel to the EU, but the future of this relationship is now far from certain. For the moment, Rosatom, Russia’s state-owned and primary vendor of nuclear products, has managed to skirt EU sanctions and continue operating, but how long can this last and what does it mean for nuclear energy in Europe?
In terms of unenriched Uranium ore, Russia is the third largest supplier to the EU. In 2021 it accounted for 19.69% of supply, just behind Kazakhstan at 22.99% and Nigeria at 24.26%. This equates to 2,358 tU (tons of raw Uranium) and roughly €210 million paid to Russian vendors in 2021. However, Russia’s position in third place can be somewhat misleading, according to the World Nuclear Association and other sources, Rosatom owns significant stakes in uranium mining and processing in Kazakhstan. Nigeria has been ramping up its supply of uranium ore in recent years with an increase of 13.7% between 2020 and 2021. Considering the ongoing expansion of mining operations in the country, Nigeria may emerge as a leading supplier for Europe, if output can be maintained.
Unenriched uranium ore is only half of the equation when it comes to generating nuclear energy. The other key ingredient is refined or enriched uranium, suitable for nuclear fuel production. Europe is dependent on foreign enrichment services. While Europe itself manages some 62% of its enrichment needs, as of 2021, 31% is still sourced from Russian providers. The two primary Russian providers, according to Euratom, are Tenex and TVEL, which are both subsidiaries of Rosatom. Over the past few years, EU domestic enrichment rates have decreased, between 2019 and 2020 alone Euratom marked a 9% decrease in its share. In order to ensure security of supply in this sector, Europe must reverse this trend and look for third country partners. The current non-Russian and non-EU supply of enrichment services amounts to an astonishingly low 7%, a critical failure in market diversification.
The other side to the issue with enriched Uranium supply is the specific fuel configuration for reactors. Of the 103 active nuclear reactors in the EU, 18 are of the Russian designed VVER-440 or VVER-1000 models and depend greatly on fuel supply from TVEL. While many of these reactors are holdovers from original Soviet construction and are set to be phased out in the long term, they still represent an imminent threat. Mitigating this however, the US’s Westinghouse, a leading provider of nuclear infrastructure, is currently expanding its capacity to produce fuel at least for the VVER-1000 models; this has already been successful in Ukraine.
The situation for Europe’s uranium supply is precarious and the fact Russia’s supply has not yet collapsed, is of little consolation. Nonetheless, there are options on the table and unlike other commodities, uranium has the potential for a diverse supply chain with multiple partners. Two key questions are how long will it take to reorganise these highly complex, infrastructure heavy supply chains and how long will the EU continue its economic relationship with Russia?
