Which risk increases when spent nuclear fuel rods, submerged in a cooling pool, undergo cladding failure?

💡 Explanation

Enhanced radiochemical contamination increases when cladding fails, because the released radionuclides undergo alpha and beta decay, spreading radioactive isotopes into the surrounding water via diffusion; therefore, pool contamination escalates, rather than affecting reactivity characteristics.
