The dangerous limit where a layer of steam suddenly coats a fuel rod, preventing liquid coolant from touching it and causing the rod to overheat, is primarily known as Critical Heat Flux (CHF). The event or phenomenon itself, which marks the transition to this dangerous state, is called Departure from Nucleate Boiling (DNB).
A fuel rod contains nuclear fuel that generates intense heat through nuclear fission. A coolant, typically liquid water in many reactor designs, circulates around these rods to absorb and remove this heat. Under normal operating conditions, heat is transferred efficiently f....
