Advancing Energy Solutions: Nuclear Power in a Sustainable Future

Nuclear power relies on a process called Nuclear fission. This is the process of heavier nuclei, such as uranium, being split up into lighter nuclei and neutrons. When given enough energy to do so, usually by firing a slow-moving neutron at a radioactive nucleus, the nuclei will split into constituents which include an amount of lighter nuclei, and two or more neutrons. The production of extra neutrons is important, as only one neutron is required to produce a nuclear fission reaction. (this means that a chain reaction is set up, as more and more neutrons are produced to ignite further fission reactions which then produce even more neutrons). When a nuclear fission reaction takes place, a LOT of energy is released. This can be represented via Einstein's famous equation: E = mc2

Why nuclear energy is better than fossil fuels

Transitioning away from fossil fuels is central to efforts to curtail climate change, clean up the air, and slow biodiversity loss. A side-by-side comparison reveals that nuclear power is far better than fossil fuels. According to the Center for Climate and Energy Solutions, coal plants generate around 2,200 lbs of carbon pollution per megawatt-hour (MWh), natural gas generates 1,100 lbs of CO2 per MWh while nuclear does not generate any.  The overwhelming logic of nuclear power is impossible to ignore. 

Nuclear energy has averted millions of tons of carbon pollution. This is energy that would otherwise have been generated by fossil fuels.  Each year more than 470 million metric tons of CO2 emissions are avoided by nuclear power in the U.S. alone. That is equivalent to taking nearly 100 million combustion engines off the road.  According to the World Nuclear Association

Nuclear energy is a central part of our efforts to transition away from fossil fuels. As reported by Real Clear Energy, “We have more and more member states recognizing that, in order to achieve the decarbonization goals, we need nuclear in the mix,” an EU industry representative was quoted as saying. Speaking about the energy crisis caused by Russia’s war, the same representative also said, “I think more and more people are starting to recognize the risk of depending on imports”.  Russia’s war of choice in Ukraine adds to the rationale for supporting nuclear power. As reported by the Economist, the effort to transition away from Russian fossil fuels is making nuclear energy increasingly attractive.

Advantages of nuclear power compared to renewable energy

Nuclear energy has advantages over renewables in terms of reliability, GHG emissions, land use, and waste. Nuclear is far more reliable (dispatchable) than renewables like wind and solar. Nuclear plants keep churning out energy even when the wind is not blowing, and the sun is not shining. 

Nuclear is also one of the cleanest sources of energy. Recent research published in the Journal of Cleaner Production found that the emission of GHGs and natural resource use associated with nuclear power generation was similar to that of renewable energy.  An analysis by the European Commission indicates that in terms of full-cycle production, the emissions from nuclear are around the same as wind.  Other studies have concluded that nuclear power may be even cleaner than solar. 

Economic benefits:

Nuclear energy has several economic advantages over other forms of energy, including its low operating costs, its ability to provide stable and reliable baseload power, and its minimal greenhouse gas emissions.

1. Low Operating Costs in the Long Run: Nuclear power plants, once built and set up, can have relatively low operating costs compared to other forms of energy. This is due to their high capacity factors and low fuel requirements. The average operating cost of a nuclear power plant in the United States in 2020 was 2.14 cents per kilowatt-hour (kWh), which is lower than coal-fired (6.81 cents/kWh) and natural gas-fired (3.27 cents/kWh) power plants.

2. Stable and Reliable Baseload Power: Nuclear power plants are well-suited for providing stable and reliable baseload power, meeting the minimum level of electricity demand around the clock. Unlike some other renewable energy sources dependent on weather conditions, nuclear power plants can operate continuously for long periods. They have an average capacity factor of around 80%, which is much higher than wind power (around 25%) and solar power (15-20%).

3. Minimal Greenhouse Gas Emissions: Nuclear energy emits minimal greenhouse gasses compared to fossil fuels like coal, oil, and natural gas. With only around 12 grams of carbon dioxide equivalent (CO2e) per kilowatt-hour (kWh) of electricity generated, it is significantly lower than coal-fired (820 grams CO2e/kWh) and natural gas-fired (490 grams CO2e/kWh) power plants.

4. Safety Improvements: Modern nuclear power plants are safer and more secure than older designs. Stringent regulations and oversight from organizations like the International Atomic Energy Agency (IAEA) help ensure the safety of nuclear facilities. With hundreds of operating nuclear power plants worldwide, the track record shows that nuclear energy is becoming safer.

5. Job Creation and Economic Growth: The nuclear energy industry contributes significantly to job creation and economic growth. In the U.S., it supports approximately 475,000 jobs and contributes around $60 billion to the economy each year, as per the Nuclear Energy Institute.

While these are indeed significant advantages of nuclear energy, it's essential to acknowledge that there are also challenges and concerns associated with this energy source. These may include issues of radioactive waste management, high initial construction costs, public perception and acceptance, and the potential for nuclear accidents (though the risk has been significantly reduced through improved safety measures). As with any energy source, it's essential to weigh the benefits and drawbacks to make informed decisions about our energy mix and future sustainability goals.

Nuclear waste danger

Radioactive waste poses a significant environmental and health risk due to its radioactivity, but it will naturally decay over time, becoming less hazardous. The decay process involves unstable atomic nuclei emitting radiation, transforming into more stable forms. This decay rate is measured by the material's half-life, varying from hours to hundreds of thousands of years, depending on the specific radioactive isotopes involved.

Proper management of radioactive waste is crucial to ensure safety during the decay process. Specialized containment and storage facilities are employed to isolate waste from the environment and prevent potential harm to living organisms. Regulatory agencies establish guidelines and protocols for the safe handling and disposal of radioactive waste, prioritizing long-term safety. By adhering to these measures, we can mitigate the risks associated with radioactive waste and protect both current and future generations from its potential adverse effects.
