Assignment 1: Discussion—The Promises and Perils of Nuclear Power The T
Discuss the scientific and technical concepts related to the use of nuclear power as an energy resource. Address the following in your response: How is energy released in a nuclear reaction? How are nuclear reactions controlled? What elements are involved in nuclear power production? What nuclear forces are involved? Explain the advantages and disadvantages of nuclear energy, detailing issues related to production, delivery, cost, radiation, air quality, and waste. Identify a country whose electricity production infrastructure relies heavily on nuclear power. Compare and contrast the use of nuclear power in the United States with this country. Provide examples of the use of nuclear power in your community or state. Consider the three major nuclear accidents in the industry’s history: Three Mile Island, Chernobyl, and Fukushima Dai-Ichi. What lessons have been learned from these accidents to improve safety?

Nuclear power harnesses the energy released during nuclear reactions to generate electricity, representing a significant component of the global energy mix. The fundamental process involves nuclear fission, where heavy atomic nuclei split into lighter nuclei, releasing substantial amounts of energy. This process predominantly involves uranium-235, a fissile material, which absorbs a neutron and undergoes splitting, releasing heat, neutrons, and radiation. The released neutrons can induce further fission in a chain reaction, which is controlled within nuclear reactors by using neutron moderators to slow neutrons and control rods to absorb excess neutrons, thereby regulating the reaction rate (World Nuclear Association, 2020). The main nuclear forces involved include the strong nuclear force, which binds protons and neutrons in the nucleus, and electromagnetic forces, which cause repulsion among positively charged protons.
The appeal of nuclear energy stems from its high energy density, low greenhouse gas emissions, and ability to provide a stable, reliable power supply. However, it also presents notable disadvantages. The risks associated with nuclear power include the potential for catastrophic accidents, radioactive waste management challenges, high capital costs for plant construction, and concerns over radiation exposure and air quality degradation. The disposal of spent nuclear fuel remains a critical environmental issue, as it contains long-lived radioactive isotopes that require secure, long-term storage solutions (United Nations Scientific Committee on the Effects of Atomic Radiation, 2014). Additionally, the prospect of nuclear proliferation and security risks further complicate nuclear power's role in energy policy.
France exemplifies a country heavily reliant on nuclear power, deriving approximately 70% of its electricity from nuclear reactors, making it one of the world's leaders in nuclear energy (International Atomic Energy Agency, 2021). Compared to the United States, which has a diversified energy portfolio with about 20% of its electricity generated through nuclear power, France’s infrastructure is predominantly focused on nuclear, with lessons learned emphasizing strict safety protocols, robust regulatory oversight, and international cooperation. In the United States, nuclear power contributes significantly to the electrical grid, especially in states like Illinois and South Carolina, where numerous reactors provide large-scale power. My community has seen sentiments around nuclear energy, often balancing concerns about safety with its role in reducing carbon emissions.
The history of nuclear accidents has underscored the importance of rigorous safety measures and technological advancements. The Three Mile Island accident highlighted the necessity of improved emergency response protocols and reactor safety systems. The Chernobyl disaster underscored the dangers of inadequate safety culture and technological design flaws, prompting widespread reforms in safety standards worldwide. The Fukushima Dai-Ichi accident demonstrated the vulnerability of nuclear facilities to natural disasters and the need for resilient infrastructure, emergency preparedness, and adaptive safety features. Lessons from these incidents have led to the development of advanced reactor designs, safety culture improvements, and international safety standards (International Atomic Energy Agency, 2012). Continuous innovation and adherence to safety protocols are crucial in making nuclear power a safer, sustainable energy source.
