Consider the case of bombardment of `""^(235)U` nucleus with a thermal neutron. The fission products are `""^(95)Moand""^(139)La` and two neutrons. Calculate the energy released. (Rest masses of the nuclides : `""^(235)U=235.0439u,""_(0)^(1)n=1.0087u,""^(95)Mo=94.9058u,""^(139)La=138.9061u` Take 1 u = 931MeV).

Text Solution

Verified by Experts

Total rest mass (initial) = 236.0526u
Total rest mass (final) = 235.8293u
Decrease in rest mass due to fission = 0.2233 u
Energy released
= `0.2233uxx931(MeV)/u=207.9MeV`.

In a fusion reactor, the reaction occurs in two stages. (i) Two deuterium (""_(1)^(2)D) nuclei fuse to form a tritium (""_(1)^(3)T) nucleus with a proton as product. (ii) A tritium nucleus fuses with another deuterium nucleus to form a helium (""_(2)^(4)He) nucleus with neutron as another product. Find (a) the energy released in each stage. (b) the energy released in the combined reaction per deuterium and (c) what percentage of the mass energy of the initial deuterium is released?
