Investing in nuclear energy: are we at a new dawn?

Historically, fuel consumption has been on a modest scale, but growing urbanisation has led to rising fuel consumption by households, including wood, coal, coke and kerosene. This progressed to natural gas for heating and cooking in order to increase energy content and reduce indoor localised smoke. In cities, large, urbanised areas have suffered from pollution from coal-fired power stations, industrial processes, and vehicle pollution.

Globally, the total greenhouse gas (GHG) balance has been allowed to materially increase without penalty for a century, but with evidence of global climate, weather and ecological systems approaching or breaching their planetary boundaries because of anthropogenic, human-influenced GHG emissions, we have seen climate change agreements and regulation accelerating. The decarbonisation of the global economy is being facilitated by the provision of renewable electric energy from wind, solar and hydroelectric power, and in road transport the shift from hydrocarbon to battery electric power, with the ultimate aim of removing all pollution from fossil fuel combustion.

To be genuinely sustainable, an ideal energy source should be renewable i.e. infinitely usable or replaceable to avoid depleting finite natural resources and polluting the environment.

Time to reconsider nuclear?

The European Union is trying to achieve several objectives simultaneously, these include the phasing out of coal, climate neutrality, lower reliance on imported natural gas, as well as greater energy independence and security. The attainment of these goals may be assisted by bringing nuclear power into the mix. The recent geopolitical turmoil surrounding Russia and the Ukraine only serves to magnify some of these issues. 

While natural gas has many positive benefits that has seen it rapidly displacing coal as a transitional energy source, it is still a non-renewable fossil fuel and cannot be considered truly green nor sustainable in its own right.

Nuclear power is considered by the Global Natural Resources Team to be much cleaner than natural gas, as it produces no greenhouse gases. It can be an excellent base load electricity supply, providing countries with dependable energy security, which historically was the case in the US, France, Germany, Japan, Russia, and South Korea. Furthermore, nuclear energy is typically produced in countries that are geopolitically stable. Wind, solar and hydro are cleaner than nuclear because they do not produce nuclear waste – i.e. carbon dioxide when power is produced so are considered cleaner than using natural gas or coal. However, one issue is that these energy sources are intermittent and require storage and ‘spinning reserve’ for the energy grid to function effectively. Nuclear power is the only spinning reserve that does not produce greenhouse gases.

The problems with nuclear

The main impediments to nuclear power growth have been economics, waste management and public perception. Nuclear power plants are complex to build and operate. The projects generally take between five to ten years to build, are frequently delivered significantly over budget and behind schedule, with some failing to complete construction or obtain financing. However, these are engineering and funding issues, which can be overcome if there is the political will to include nuclear power in a country’s energy mix.

Nuclear power also remains controversial because of the risk of rogue production of nuclear weapons, the extremely long life of nuclear waste with its need for secure long-term storage, the economics of larger reactors and the environmental impact of nuclear accidents.

After the 2011 Tōhoku earthquake close to the east coast of Japan, the nuclear reactors there shut down successfully, but the tsunami very shortly afterwards flooded the nuclear plants and cut power to the electrical pumps resulting in three reactor units exploding. Following the disaster, many Japanese nuclear power plants remained offline; Japan's experience has even caused ripple effects elsewhere, with Germany shutting down its reactors (and consequently is driving an increase in coal-fired power usage). Meanwhile, France remains committed to nuclear power, but has an ageing nuclear fleet of reactors with maintenance and safety issues to handle.

But there are solutions

These issues could potentially be resolved by shifting nuclear fuel from uranium to thorium, from which nuclear weapons cannot be made. This may take some time because thorium research has been underfunded so the focus is likely to remain on uranium for the foreseeable future. Smaller modular reactor (SMR) units can help mitigate the risk of accidents and have much lower upfront capital requirements, smaller footprints, lower water-cooling requirements, and are being designed with inherent passive safety features that would have avoided previous incidents such as those at the Fukushima and Three Mile Island in Pennsylvania nuclear plants. Finally, availability of secure storage can be increased for the long-lived waste, which while dangerous is relatively small in physical terms.

The key point is that there are unavoidable trade-offs everywhere within the energy system. A world powered only by renewable energy would be a wonderful thing but the harsh reality of managing a power grid is that a ‘spinning reserve’ is required to keep the system stable. This could be achieved with power storage (batteries), hydrogen or nuclear power, or most likely some combination of all.

Recognition of this seems to be rising with the European Commission's recent announcement to classify nuclear power as green energy under the Taxonomy Regulation* that will be finalised later this year, as it seeks to eliminate coal, achieve net zero carbon, reduce the reliance on imported natural gas and increase energy independence. The European Taxonomy considers the full life cycle of uranium use and storage of the spent fuel, with Finland a world leader in nuclear energy generation highlighted by the country’s foresight and commitment to build the Onkalo spent nuclear fuel repository.

The proposed labelling of nuclear as a green energy comes with some caveats. Gas plants can be considered green if the facility switches to low-carbon or renewable gases, such as biomass or hydrogen produced with renewable energy, by 2035. Additionally, nuclear power plants must show how they will fund and safely manage and dispose of radioactive waste.

The uranium market

The uranium market has tightened considerably in the last year, with demand outstripping supply, resulting in higher prices. There has been depleting supply after a ten-year bear market (falling prices), alongside a lack of investment in new mine supply with a reduction in inventory accelerated by recently launched physical unit trusts similar to those seen in other metals.

The primary interest for our team is the discovery of high-quality, world-class, socially and economically viable uranium resources that can be mined in an environmentally-friendly way (underground ideally, via traditional or in-situ leaching). 

Such uranium sources are found in relatively few countries, primarily in Kazakhstan and Canada, and are essential to deliver uranium to fuel assembly plants to enable nuclear power generation.

Responsible miners

If nuclear energy usage does gain more traction, it is unlikely to be driven by thorium as uranium solutions are further advanced. Therefore newly-discovered deposits, such as NexGen Energy’s discovery in the South West Athabasca basin in Saskatchewan, Canada will be sorely needed. The Rook discovery in that area is particularly interesting because of its location in highly competent basement bedrock, which makes it amenable to bulk low-cost underground mining, with the tailings (benign mining by-products) used as backfill resulting in a minimal surface footprint.

Given the increasing focus on environmental, social and governance (ESG) considerations, resource companies also need to be responsible corporate citizens. NexGen has sought to incorporate landowner requirements into its development proposal, with a study agreement involving communities within the project area, demonstrating to investors a commitment to environmental stewardship, health & safety, reclamation, and community & indigenous relationships.

In summary

Given nuclear power’s probable green energy classification, fuels such as uranium could see a new surge in demand, and along with this may create some attractive investment opportunities. Rising demand needs to be met with responsible supply. Active management enables ESG factors to be actively incorporated into investment decisions as well as investor engagement. Investing in partnership with companies with a focus on ESG and effective stewardship makes sense as resource companies that have a strong focus on ESG considerations tend to be more appreciated by the market in the long run.

Notes: *The European Union Taxonomy is a technical set of rules, focusing on the classification of what can be deemed as ‘sustainable’ and regulates what can be said to be environmentally friendly, to enable climate-conscious investors to make informed decisions. According to the EU Taxonomy Regulation, a sustainable economic activity must: Contribute to at least one of six environmental objectives listed in the Taxonomy (climate change mitigation, (2) climate change adaptation, (3) sustainable use and protection of water and marine resources, (4) transition to a circular economy, (5) pollution prevention and control, and (6) protection and restoration of biodiversity and ecosystems. Do no significant harm to any of the other objectives, while respecting basic human rights and labour standards. Base load electricity refers to the minimum amount of electric power that needs to be supplied to the electrical grid at any given time. Spinning reserves are power generators that are typically already online and can quickly increase output to meet changes in demand. In situ leaching (ISL), also known as solution mining, or in situ recovery (ISR) in North America, involves leaving the ore where it is in the ground, and recovering the minerals from it by dissolving them and pumping the pregnant solution to the surface where the minerals can be recovered. Thus, there is little surface disturbance and no tailings or waste rock generated. Environmental, Social and Governance (ESG) or sustainable investing considers factors beyond traditional financial analysis. This may limit available investments and cause performance and exposures to differ from, and potentially be more concentrated in certain areas than the broader market.
