Maximum mark:
One possible fission reaction of uranium is
Mass of one atom of
Binding energy per nudeon for UMeV
Binding energy per nucleon for MeV
Binding energy per nucleon for SrMeV
ai State what is meant by binding energy of a nucleus:
aii Outine why quantities such as atomic mass and nuclear binding energy are often expressed in nonsI units.
aiii Show that the energy released in the reaction is about MeV.
A nuclear power station uses US as fuel. Assume that evey fission reaction of U gives rise to MeV of energy.
