In a commercial nuclear fission reactor, uranium-235 nuclei undergo fission to release energy. During a specific operating interval, the total nuclear energy released by these fission reactions is 1.35 × 1011 J.
This energy, EEE, is produced by the conversion of a small amount of mass, Δm\Delta mΔm, according to the mass-energy equivalence equation:
E=Δmc2E = \Delta m c^2E=Δmc2
where c c\,c represents the speed of light, 3.0 × 108 m/s.
Calculate the mass defect (the decrease in mass), Δm\Delta mΔm, that corresponds to this energy release. Show your working.
