Answer:
A nuclear process that has relatively few radioactive by-products is referred to as a "clean" or "low-waste" nuclear process. One example of such a process is nuclear fusion, where lightweight atomic nuclei combine to form heavier nuclei, releasing a significant amount of energy in the process. Fusion reactions produce less long-lived radioactive waste compared to nuclear fission, which is the splitting of heavy atomic nuclei that is commonly used in nuclear power plants.
