Which risk increases during control rod ejection in a pressurized water reactor?

💡 Explanation

Prompt criticality risk increases because positive reactivity is rapidly inserted, overwhelming control mechanisms. This induces a rapid, uncontrolled chain reaction leading the fission rate increasing dramatically thus causing prompt criticality rather than delayed neutron effects which are too slow to compensate.
