← ScienceWhich process enables sustained energy output when reactor criticality is reached?
A)Neutron moderation slowing chain reaction✓
B)Increased magnetic plasma confinement strength
C)Control rod absorbing excess neutrons
D)Coolant prevents fuel material melting
💡 Explanation
Sustained energy output occurs due to neutron moderation, because this process slows neutrons to thermal energies, promoting further uranium-235 fission, initiating chain reaction. Therefore optimal regulated speed of the process results, rather than uncontrolled reaction.
