(a) Explain the terms nuclear fission and nuclear fusion.~(b) State two advantages of fusion over fission and explain briefly why, in spite of these advantages,fusion is not normally usedfor the generation of power.
(c) \(^{238} _{92} U\) is a long half- life alpha emitter and decays to thorium Th which, in turn decays by beta emission with a small decay constantto an isotope of protactinium Pa. The protactinium decay scheme of \(^{238} _{92} U \) as stated above.
