Which risk increases when supercritical fission is sustained?

💡 Explanation

Fuel element structural failure increases because excessive neutron flux causes rapid, uneven heating via volumetric nuclear heat deposition, therefore thermal stresses exceed material limits rather than breeding or more radiation, due to the uncontrolled fission.
