Which risk increases when controlled chain fission reactions accelerate?

💡 Explanation

Fuel cladding breach risk increases because increased energy causes a rapid rise in fuel temperature, therefore exceeding material limits during uncontrolled thermal expansion, rather than changes in neutron moderation which would also affect reaction rate.
