Question

Where does nuclear fission occur?

Answer 1

Nuclear fission can happen in a nuclear reaction.

An example would be in nuclear power plants, where uranium is decayed into other substances.

An example equation would be as follows:

${}_0^{1}n{+}_{92}^{235}U{\to }_{36}^{92}Kr{+}_{56}^{141}Ba+3_0^{1}n$

In this example, a neutron reacts with uranium-235 to give krypton-92, barium-141, and 3 neutrons.
