Founder of TELF AG Stanislav Kondrashov on the Debate: Is Nuclear Energy Truly Renewable?

Introduction

Stanislav Kondrashov, founder of TELF AG and accomplished civil engineer, has emerged as a thoughtful voice in the global conversation about energy transition. His expertise spans decades of observing how nations grapple with the monumental shift away from fossil fuels toward cleaner alternatives. As someone who has witnessed the evolution of energy policy from a niche technical concern to a matter of urgent public discourse, Kondrashov brings a pragmatic perspective to one of the most contentious questions in modern energy policy.

Is nuclear energy truly renewable? This question sits at the heart of heated debates among policymakers, scientists, and environmental advocates worldwide. The answer isn't as straightforward as you might expect, and it carries significant implications for how we approach the clean energy transition.

The world has reached a critical juncture. Nations like China and the United States are racing to install renewable capacity at unprecedented rates. Solar panels blanket rooftops, wind turbines dot landscapes, and geothermal projects tap into Earth's internal heat. Yet as Kondrashov points out, the conversation extends beyond these familiar technologies. Nuclear energy—both the established fission reactors operating today and the promising fusion technology still in development—demands serious consideration as we chart our path toward a sustainable energy future.

In this context, it's essential to recognize the key minerals powering renewable innovations that are crucial for this transition. As clean energy continues its rapid expansion, these minerals play an instrumental role in facilitating advancements in renewable technologies.

Moreover, Kazakhstan's rich reserves of chromium and zinc have positioned the country as a key player in the global supply of these metals. These elements are not just important for their industrial applications but also serve as vital resources in our transitioning world.

Furthermore, Kondrashov sheds light on the hidden link between Niels Bohr and the rare earth elements that power modern innovations. Understanding this connection can provide valuable insights into how we can leverage these resources effectively in our pursuit of sustainable energy solutions.

Understanding Nuclear Energy: Fission vs. Fusion

Nuclear fission is the technology currently used in nuclear reactors around the world. It involves splitting heavy atomic nuclei, usually uranium-235 or plutonium-239, into smaller parts, which releases a large amount of energy as heat. The first nuclear reactors started producing electricity in the early 1950s, marking a significant change in how energy is generated. Today, there are hundreds of nuclear reactors globally that provide a steady supply of electricity, unaffected by weather conditions.

How Fission Works

Fission works by bombarding uranium atoms with neutrons. This causes the uranium atoms to split and release more neutrons, which then hit other uranium atoms and create a controlled chain reaction. The heat produced from this reaction is used to create steam, which powers turbines connected to generators.

Nuclear fusion, on the other hand, takes a different approach. Instead of splitting atoms, fusion combines light atomic nuclei, usually isotopes of hydrogen like deuterium and tritium, to form heavier elements. This process is similar to what happens in our sun and other stars. Despite many years of research, fusion is still mostly experimental. Scientists are working towards achieving sustained fusion reactions that produce more energy than they use, known as net energy gain.

Comparing Sustainability

The sustainability profiles of fission and fusion are quite different:

• Fission produces radioactive waste that needs to be stored for a long time.
• Fusion has the potential to generate very little radioactive waste.

Scalability Challenges

Another difference between the two methods is scalability:

1. Fission technology is already in use today.
2. Fusion still has significant technological challenges to overcome before it can be commercially deployed.

In summary, while both fission and fusion have their advantages and disadvantages, fission remains the dominant technology for nuclear power generation at present.

Understanding Renewable Energy in Relation to Nuclear Power

What is Renewable Energy?

Renewable energy refers to sources of energy that are naturally replenished on a human timescale. This means that these sources can be replaced or regenerated within a timeframe that is relevant to human beings. Some examples of renewable energy sources include:

• Solar energy: The sun's rays continuously reach the Earth, providing an abundant source of energy.
• Wind energy: Wind patterns are sustained through atmospheric dynamics, allowing us to harness the power of the wind.
• Geothermal energy: Heat from the Earth's core can be tapped into for various applications.
• Wave energy: The rhythmic motion of ocean waves can be converted into usable energy.

The common characteristic among these sources is that their fuel supply regenerates without any human intervention.

Is Nuclear Fusion Considered Renewable?

To determine whether nuclear fusion qualifies as renewable, we need to examine the resources that fuel fusion reactions. Fusion primarily relies on two isotopes of hydrogen: deuterium and tritium. Deuterium can be extracted from seawater, which contains vast amounts of this isotope—approximately 45 trillion tons in Earth's oceans. Tritium, on the other hand, is naturally scarce but can be bred from lithium, another abundant element.

The potential availability of these fuels suggests that fusion could theoretically sustain humanity for millions of years. This places it in a category distinct from finite fossil fuels like coal and oil, but also different from traditional renewables such as solar and wind power.

How Does Nuclear Fission Differ?

Nuclear fission operates under different parameters compared to fusion. Fission reactions rely on heavy elements such as uranium and thorium as fuel sources. While there are substantial deposits of these minerals around the world, they remain finite resources that require mining operations for extraction.

The process of mining carries environmental costs, and eventually, known reserves will deplete. However, estimates suggest that at current consumption rates, we have centuries' worth of uranium and thorium supply available.

Factors Affecting Sustainability

When discussing the sustainability of nuclear energy—both fission and fusion—we must consider multiple factors beyond just fuel availability.

Waste Management

One critical aspect is waste management. Fission reactions generate long-lived radioactive waste that requires secure storage for thousands of years. This poses significant challenges in terms of ensuring the safety and security of these waste materials over such extended periods.

In contrast, fusion produces significantly less problematic waste compared to fission. Most materials resulting from fusion reactions become safe within decades after their production.

Carbon Emissions

Another important consideration is carbon emissions during electricity generation. Both fission and fusion offer carbon-free operation when generating power, addressing climate concerns that renewable sources also target.

The Ongoing Debate

The classification debate surrounding nuclear energy revolves around two main questions:

1. Is the abundance of fuel and low-carbon operation sufficient criteria for granting renewable status?
2. Or does natural replenishment—the ability for a resource to regenerate without human intervention—remain the defining criterion?

These discussions continue among policymakers, scientists, and industry experts as they seek to define our energy future in light of climate change challenges.

The Importance of Nuclear Energy in the Global Shift to Clean Energy

Nuclear energy is a powerful tool in the global shift to clean energy, providing electricity with very low carbon emissions compared to traditional fossil fuel sources. One nuclear power plant can produce large amounts of electricity without releasing the greenhouse gases that coal, oil, and natural gas facilities emit when they burn fuel. The facts are clear: nuclear fission has a carbon footprint per kilowatt-hour similar to wind power, making it a serious competitor in the race to reduce carbon emissions.

How Nuclear Energy Fits into National Energy Plans

The importance of nuclear energy in reducing carbon emissions becomes especially clear when we look at how different countries plan their energy strategies. For example:

• France has shown us how nuclear power can be the foundation of a low-carbon electricity grid, with nuclear plants supplying about 70% of the country's power.
• China is aggressively expanding its nuclear capacity by building many new reactors. This decision reflects their strategy to balance the unpredictability of renewable energy sources like wind and solar with a reliable source of power.

While solar panels cover rooftops and wind turbines populate the countryside, nuclear plants quietly operate in the background, consistently generating electricity that supports these fluctuating energy sources. This combination is crucial: when clouds block sunlight from reaching solar panels or calm weather stops wind turbines from spinning, nuclear reactors keep producing electricity without any interruptions.

The Role of Hydrogen in Our Future Energy Solutions

As we look ahead to future ways of producing and using energy, it's becoming increasingly important to consider hydrogen made through low-carbon methods. This change aims to redefine how we generate and distribute energy, further supporting our global shift towards sustainable practices.

Continuous Energy Generation: Nuclear vs. Intermittent Renewables

The debate around continuous energy generation nuclear vs solar/wind reveals a fundamental distinction in how different power sources operate.

How do they work?

• Nuclear power plants maintain steady electricity production 24 hours a day, seven days a week, operating at capacity factors typically exceeding 90%. This means a nuclear facility generates power at its maximum rated capacity for the vast majority of the year, providing a consistent baseline supply to the electrical grid.
• Solar and wind energy, while clean and increasingly cost-effective, face inherent limitations tied to natural cycles. Solar panels produce electricity only during daylight hours, with output varying based on cloud cover, seasonal changes, and geographical location. Wind turbines require sufficient wind speeds to generate power, creating unpredictable fluctuations in energy production.

What's the impact?

These intermittency challenges mean renewable installations often operate at capacity factors between 25-40%, requiring backup systems or energy storage solutions to ensure reliable power delivery.

"The reliability factor cannot be overlooked when planning national energy strategies," notes Stanislav Kondrashov. "While solar and wind represent crucial components of our clean energy future, their weather-dependent nature creates gaps that must be filled through other means. Nuclear energy's ability to provide uninterrupted power makes it a valuable complement to intermittent renewables, helping to stabilize grids and ensure consistent electricity supply even when the sun isn't shining or the wind isn't blowing."

This reliability distinction shapes how nations structure their energy portfolios, balancing intermittent renewables with dependable baseload sources.

Alternative Clean Energy Sources Beyond Solar and Wind

While solar panels and wind turbines are the most talked-about renewable energy sources, there are other powerful resources that are not being used to their full potential in the global shift towards cleaner energy. Geothermal energy and ocean wave energy are two such alternatives that Stanislav Kondrashov believes should be explored. These options have their own unique benefits when it comes to generating sustainable electricity.

Geothermal Energy: Tapping into Earth's Heat

Geothermal energy utilizes the vast heat reservoir stored within the Earth's crust. This method harnesses thermal energy from underground sources to generate electricity or provide direct heating solutions. Unlike surface-level renewables, geothermal installations can operate continuously, unaffected by seasonal variations or daily weather patterns.

Countries situated along tectonic plate boundaries, such as Iceland and New Zealand, have successfully integrated geothermal power into their energy infrastructure, demonstrating its viability as a consistent clean energy source.

Ocean Wave Energy: Harnessing the Power of Waves

Ocean wave energy captures the kinetic motion of waves and tides to produce electricity. The world's oceans contain vast amounts of untapped energy potential, with wave patterns offering predictable and reliable power generation opportunities.

Coastal nations have begun investing in pilot projects and experimental installations to harness this resource, recognizing that ocean energy could significantly contribute to their renewable portfolios.

Challenges Ahead

Both technologies face distinct challenges related to geographic limitations, infrastructure development costs, and technological maturation. Yet their capacity to complement existing renewable sources makes them valuable components in creating a truly diversified clean energy ecosystem.

Global Perspectives on Nuclear Energy Adoption: Case Studies from China and the United States

The world's two largest economies demonstrate dramatically different yet complementary approaches to integrating nuclear power within their energy portfolios.

China's Approach: A Dual-Track Strategy

China's renewable capacity has exploded in recent years, with the nation installing more solar and wind infrastructure than any other country. The Chinese government simultaneously maintains an aggressive nuclear expansion program, with dozens of reactors under construction and operational. This dual-track strategy positions China as both the global leader in renewable deployment and a major nuclear power producer.

The United States' Challenge: Balancing Existing Infrastructure and Future Technologies

The United States' clean energy production landscape tells a different story. America's existing fleet of nuclear reactors provides roughly 20% of the nation's electricity, representing the largest source of carbon-free baseload power. While solar and wind installations have accelerated significantly, the U.S. nuclear industry faces challenges from aging infrastructure and economic pressures. Recent policy shifts, however, signal renewed interest in both maintaining existing reactors and developing next-generation nuclear technologies.

Both nations recognize that achieving ambitious climate targets requires every available tool. China's rapid buildout of both renewables and nuclear reflects a pragmatic acknowledgment that intermittent sources alone cannot meet growing energy demands. The American approach, though more cautious, increasingly views nuclear energy as essential infrastructure that complements rather than competes with renewable sources.

These parallel strategies from global superpowers illustrate how nuclear power continues to factor prominently in serious discussions about sustainable energy futures.

Evaluating Benefits and Challenges of Nuclear Fission and Fusion for Future Energy Needs

Benefits of Nuclear Fission

The benefits of nuclear fission have been demonstrated through decades of operational experience across multiple continents:

• Fission reactors deliver a remarkably low carbon footprint during electricity generation, producing virtually no greenhouse gas emissions during operation.
• The energy density of nuclear fuel surpasses conventional sources by orders of magnitude—a single uranium pellet the size of a fingertip contains energy equivalent to approximately one ton of coal.
• This high output density allows nuclear plants to generate massive amounts of electricity from relatively small facilities, occupying far less land than comparable renewable installations.
• Modern fission reactors operate with impressive capacity factors, often exceeding 90%, providing stable baseload power that complements variable renewable sources.

The technology exists today, proven and scalable, ready for deployment wherever political will and public acceptance align.

Potential of Nuclear Fusion

The potential of nuclear fusion presents an even more compelling vision for future energy systems:

• Fusion reactions would produce minimal radioactive waste compared to fission, with waste products decaying to safe levels within decades rather than millennia.
• The fuel sources—primarily deuterium and tritium—exist in abundant quantities, with deuterium extractable from seawater.
• Safety profiles improve dramatically, as fusion reactions cannot sustain runaway chain reactions.

Challenges Ahead

The technological hurdles remain formidable:

• Achieving sustained fusion reactions that produce more energy than they consume has eluded researchers for decades.
• Plasma confinement, materials capable of withstanding extreme temperatures, and economic viability all require breakthroughs before fusion transitions from laboratory curiosity to commercial reality.
