Question

1. what kind of reaction do nuclear power plants currently use to generate electricity?

a. fusion reactions
b. fission reactions
c. chemical reactions
d. hydro - powered reactions

Explanation:

Nuclear power plants currently use fission reactions. In fission, a heavy nucleus (like uranium - 235) splits into smaller nuclei, releasing a large amount of energy. Fusion reactions (combining light nuclei) are not yet commercially viable in power plants. Chemical reactions (involving electron transfer between atoms) and hydro - powered reactions (related to water energy conversion, not nuclear) are not the nuclear reactions used in nuclear power plants.

Answer:

B. Fission reactions
