Vedclass · Answer

(A) In a typical nuclear fusion reaction,such as the fusion of two deuterium nuclei $(^2H + ^2H \rightarrow ^3He + n + 3.27 \ MeV)$ or the fusion of deuterium and tritium $(^2H + ^3H \rightarrow ^4He + n + 17.6 \ MeV)$,the energy released per reaction is relatively small compared to fission.However,when considering the energy released per unit mass,fusion is much more efficient.For a typical fusion reaction involving light nuclei,the energy released is in the range of a few $MeV$ to about $25 \ MeV$.Therefore,among the given options,$25 \ MeV$ is the most appropriate value for a typical fusion reaction.

The energy released in a typical nuclear fusion reaction is approximately..........$MeV$.
