Which answer would score higher? Not sure where to start? Explain this Answer A After absorbing a neutron, the large unstable nucleus splits into two smaller nuclei and releases gamma rays, kinetic energy and two or three neutrons. Those neutrons cannot trigger further fissions, so the reactor’s continuing energy release depends on repeated spontaneous fission. Answer B After absorbing a neutron, the large unstable nucleus splits into two smaller nuclei and releases gamma rays, kinetic energy and two or three neutrons. Those neutrons may be absorbed by other unstable nuclei, causing further fissions that continue the chain reaction.
