Which is most likely why many scientists reject the cold fusion theory?

Because many calculations using conventional theory shown that even though a little fusion may take place  under low-energy condition, the amount required to reach the claimed heat in cold fusion theory is impossible, which make many Scientist doubt this theory 

This is what i found “nuclear fuel is material used in nuclear power stations to produce heat to power turbines. heat is created when nuclear fuel undergoes nuclear fission. most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission.” i hope this you for what your looking for. can you plz mark me brainliest?

Is there a diagram/picture you can provide? it seems this question goes along with a
