Which risk increases when reactor coolant contains excess protium isotopes?

💡 Explanation

Neutron moderation efficiency reduces because protium readily absorbs neutrons, lowering the probability of fission; therefore, the chain reaction sustains less effectively rather than fuel oxidation affecting stability under certain chemical conditions.
