← ScienceWhich consequence results when a fuel rod's cladding fails during nuclear fission?
A)Control rod system pressure spikes
B)Core neutron flux increases rapidly✓
C)Moderator temperature irreversibly decreases
D)Steam generator corrosion accelerates sharply
💡 Explanation
The nuclear chain reaction accelerates by neutron thermalization because loss of cladding allows direct moderator contact. This causes increased core activity rather than alternatives. It has this outcome rather than others because the moderators slow them, and that reaction speeds us fission, not reducing it.
