Question

radioactive fuel rods from power plants emit what kind of energy? nuclear thermal mechanical

Explanation:

Radioactive fuel rods in power plants undergo nuclear fission. Nuclear fission is a nuclear reaction where the nucleus of an atom splits, releasing nuclear energy. Thermal energy is a result of the heat generated from nuclear reactions, but the primary emitted energy type from the radioactive fuel rods (due to the fission process) is nuclear energy. Mechanical energy is more related to movement (like turbines moving due to steam, which itself is a conversion from thermal energy that originated from nuclear reactions).

Answer:

nuclear
