← ScienceWhich risk increases when criticality exceeds prompt in-core control?
A)Fuel pellet thermal expansion failure
B)Rapid uncontrolled power excursion✓
C)Delayed neutron flux drop sharply
D)Moderator void coefficient turns negative
💡 Explanation
An uncontrolled power excursion is likely above prompt criticality because neutron production accelerates immensely, causing rapid increase in the reactor power due to nuclear fission chain reaction. Therefore an excursion, rather than fuel failure will likely occur due to exponential power boost and heat generation.
