Analyse nuclear fission energy release

Paper 1, Paper 2 5 marks Difficulty 4

Total nuclear energy from repeated events

Each completed nuclear event in a nuclear reactor model releases \(221\,\text{MeV}\). Calculate total energy from \(7\times10^{12}\) events in units of \(10^{12}\,\text{MeV}\). Use the diagram labels before calculating the requested value. Enter the numerical result and choose the interpretation that matches the quantum or nuclear physics.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
