Nuclear energy has long been a topic of debate due to concerns about its environmental impact and the disposal of nuclear waste. However, a paradigm shift is underway that could revolutionize how we view nuclear waste. Not only could recycling nuclear fissile waste reduce the waste generated by current nuclear power plants, but it also […]
