Which consequence results when control rods fail during power adjustments initiating nuclear fission?

A)Uncontrolled supercriticality leading to higher power
B)Moderator decomposition halting chain reactions totally
C)Fuel enrichment falls; reaction stops completely
D)Cladding corrosion accelerates releasing coolant quickly

💡 Explanation

Uncontrolled supercriticality occurs because a failure would prevent neutron absorption via neutron moderation, setting in motion a divergent chain reaction therefore power increases, rather than merely stopping it or causing cladding effects at lower power levels.
