Question 67 – Radiation safety and nuclear energy - Questions

Figure 1 shows a nuclear fission reaction occurring inside a nuclear reactor core.

Figure 1: Diagram showing a neutron colliding with a Uranium-235 nucleus to produce a Barium-141 nucleus, a Krypton-92 nucleus, three free neutrons, and a release of energy.

The total mass of the reactants before the fission is slightly greater than the total mass of the products after the reaction. This difference is known as the change in mass.

The energy released during this nuclear reaction is related to the change in mass by the equation:

\text{energy released} = \text{change in mass} \times (\text{speed of light})^2

During one specific fission reaction, the energy released is 3.15 × 10^-11 J.

The speed of light is 3.00 × 10⁸ m/s.

Calculate the change in mass of the nuclei during this reaction.
