← ScienceWhich process increases when unstable isotopes transmute in spent fuel rods?
A)Neutron flux✓
B)Fission chain reaction
C)Doppler broadening
D)Moderator efficiency
💡 Explanation
A transmutation generates additional neutrons as unstable isotopes decay to more stable configurations; this process is termed neutron flux because neutrons are released rather than other subatomic elements. Therefore, neutron flux increase, broadening does not.
