Which risk increases when reactor fuel reaches burnup limit?

💡 Explanation

Increased burnup leads to higher concentrations of fission products; this increases intra-pellet pressure via the mechanism of gas accumulation. Cladding rupture risk increases because of pressure, rather than altered neutron dynamics; therefore A, B, and D are not directly dominant.
