← ScienceWhich outcome reduces the neutron absorption cross-section in nuclear fuel?
A)Increased nucleon binding energy homogeneity✓
B)Formation of short-lived transuranic isotopes
C)Elevated moderator void coefficient presence
D)Clustering of spontaneous fission products
💡 Explanation
More homogeneous binding energies prevent selective neutron capture via specific nuclear energy levels, which otherwise increases absorption via neutron activation; therefore, a more consistent binding energy reduces reactivity, rather than increased fission product presence influencing neutron capture probability.
