Which risk increases when spent nuclear fuel rods experience underwater corrosion?

💡 Explanation

Corrosion compromises barriers meant to contain radioactive materials. Alpha decay of many isotopes causes helium buildup, increasing corrosion rates because the helium embrittles the cladding, therefore more radioactive isotopes are released, rather than affecting reactor kinetics.
