Which consequence results when isotopic enrichment exceeds tolerance in Zircaloy cladding?

💡 Explanation

Reduced corrosion resistance develops with excessive isotopic enrichment because a change in neutron absorption cross-section causes accelerated oxidation via preferential pathways within the Zircaloy matrix, leading to corrosion; therefore, cladding fails faster; rather than strength or blockage, because those occur from creep.
