Which risk increases when a pressurized water reactor's coolant leaks?

💡 Explanation

Radioactive fission products, such as iodine-131, accumulate in the coolant during normal operation. The loss of primary coolant causes airborne release via radioactive decay, therefore more iodine-131 releases, rather than the other proposed changes in reactor dynamics during coolant loss.
