The proposal to dispose of spent nuclear fuel rods in canisters at the ocean's bottom is debated due to concerns over containment and environmental impact. While water provides effective radiation shielding, the corrosive nature of seawater and potential leaks pose significant risks. Historical examples, such as the challenges faced at Chernobyl, highlight the difficulties of maintaining containment over time. Some argue that reprocessing spent fuel could reduce waste volume and long-term radioactivity, making it safer for storage. Ultimately, the consensus leans toward the need for controlled, land-based disposal methods rather than oceanic solutions.
