Lithium: National Security, Nuclear Reactors & New Frontiers

Lithium’s unique properties and critical role in modern technology are making it one of the most important materials for the future of energy, transportation, and technology worldwide.

___________________________________________________________________________________________

Definition of a Critical Resource

Critical resources are materials essential for economic and national security with a high risk of supply disruption. Lithium fits this definition due to its indispensable role in modern technologies and limited, concentrated supply.

Lithium: History and Discovery

Lithium was discovered in 1817 by the Swedish chemist Johan August Arfwedson.

The name "lithium" is derived from the Greek word “lithos” (λίθος), which means "stone". Lithium is relatively rare but widely dispersed in the Earth’s crust. Despite this, it is not found as a free element naturally but mainly in mineral compounds.

Geographical Distribution:

  • The major global producers of lithium are:

    • Australia: The largest producer, mainly mining spodumene.

    • Chile: Large lithium brine deposits in the Atacama Desert.

    • Argentina: Part of the "Lithium Triangle," rich in salt flats with lithium brines.

    • China: Both mineral and brine sources contribute to its lithium production.

Resource Nationalism:

Some countries are increasingly asserting control over their lithium resources through:

  • Export restrictions

  • Nationalization policies

  • Strategic partnerships and joint ventures with foreign companies.

These moves aim to secure supply chains, maximize economic benefits, and promote domestic industrial growth.

Global Supply Chain and Security:

  • Dependence on a limited number of suppliers raises concerns about supply chain vulnerabilities, including:

    • Political instability

    • Trade disputes

    • Export controls

  • Many countries are actively seeking to diversify supply sources, invest in domestic lithium mining, or develop recycling programs to reduce reliance.

International Competition:

  • There is growing competition to secure lithium reserves through foreign investments and diplomatic engagements, particularly in South America and Africa.

  • Lithium’s role in national security, economic stability, and technological leadership is prompting governments to integrate lithium strategies into broader energy and industrial policies.

    • Lithium hydroxide is used to produce lithium-based greases that are stable at high temperatures and water-resistant.

  • Air purification systems:

    • Lithium compounds are used in systems designed to remove carbon dioxide and purify air, especially in closed environments like spacecraft.

Nuclear Applications:

  • Lithium plays a role in nuclear fusion reactors and nuclear reactors:

    • It acts as a coolant or neutron absorber, helping to manage heat and nuclear reactions safely.

Nuclear Reactors and Lithium's Role

There is global momentum towards deploying Small Modular Reactors (SMR’s) for clean energy, remote power supply, and industrial uses. SMRs are seen as a promising part of the future energy mix, complementing renewables by providing steady, clean power with greater flexibility.

What Are SMRs?

  • SMRs are compact nuclear reactors typically generating up to 300 MW of electricity per unit—much smaller than traditional nuclear plants.

  • Designed to be modular, allowing factory fabrication and easier transportation to sites.

  • They offer scalability: utilities can add modules incrementally as demand grows.

Why Are SMRs Rising Now?

  • Safety Improvements: SMRs incorporate passive safety features reducing risks of accidents.

  • Lower Capital Costs: Smaller size and modular construction reduce upfront investment and construction time.

  • Flexibility: Suitable for remote locations, smaller grids, and industrial applications (e.g., desalination, hydrogen production).

  • Decarbonization Goals: SMRs provide reliable, low-carbon baseload power, supporting the transition away from fossil fuels.

  • Government Support: Increased funding and regulatory frameworks are accelerating SMR development worldwide.

Global Developments:

  • Countries like the US, Canada, UK, Russia, China, and South Korea are actively investing in SMR R&D and pilot projects.

  • Some SMRs are nearing commercial deployment, with first-of-a-kind reactors expected within the next few years.

Challenges:

  • Regulatory approval processes.

  • Public acceptance and perception of nuclear energy.

  • Economic competitiveness with renewables and natural gas.

Lithium: Nuclear Applications

Role in Nuclear Reactors:

  • Neutron Absorber:
     Lithium, particularly its isotope lithium-6 (⁶Li), is used in nuclear reactors as a neutron absorber. It helps control the nuclear chain reaction by capturing neutrons, thereby stabilizing the reactor’s operation.

  • Coolant in Nuclear Reactors:
     Lithium compounds, such as lithium hydroxide (LiOH), are added to the reactor’s coolant water to maintain the pH balance and reduce corrosion of the reactor materials, improving the system’s longevity and safety.

Role in Nuclear Fusion:

  • Fusion Fuel and Blanket Material:
     Lithium is a key material in experimental fusion reactors (like tokamaks). When bombarded with neutrons during fusion reactions, lithium produces tritium (³H), a radioactive isotope of hydrogen used as a fuel in fusion reactions.

  • Neutron Shielding and Heat Transfer:
     Lithium-containing materials in the reactor blanket absorb neutrons and help transfer heat generated from the fusion process efficiently.

Market Demand and Price Fluctuations:

  • Demand for lithium has surged sharply with the growth of electric vehicles and renewable energy storage.

  • Prices of lithium compounds have experienced significant volatility due to supply constraints, geopolitical tensions, and fluctuating market expectations.

  • The market is evolving rapidly with new lithium extraction technologies and exploration activities aiming to stabilize supply and prices.

  • Increasing efforts in recycling and alternative battery chemistries also impact the long-term demand forecasts.
