From a pulsed accelerator, a burst of 1 x 1010 neutrons is introduced into a subcritical assembly consisting of an array of natural uranium rods in water. If the system has a multiplication factor of 0.97 and approximately 80% of the incident neutrons are absorbed in uranium, calculate: (a) The number of first-generation fissions that the neutrons produce in the assembly, and (b) The total fission energy in joules released in the assembly by the neutron burst?
