Nuclear fuel scarcity refers to the limited availability of materials used to generate nuclear energy, primarily uranium and plutonium. These resources are essential for powering nuclear reactors, which produce electricity. As global energy demands rise, concerns about the depletion of these fuels have emerged, prompting discussions about sustainable energy practices. The scarcity of nuclear fuel can lead to increased competition among countries and energy companies for access to these resources. Additionally, it raises questions about the long-term viability of nuclear energy as a reliable power source. Efforts to recycle spent fuel and develop alternative fuels are ongoing to address these challenges.
