Neutron fluence is the flux divided by the time; neutron current is a vector given by the dot product of neutron density and velocity

Neutron flux is a

scalar proportional to neutron density and speed; neutron current is a

vector given by the product of neutron density and velocity

Neutron flux and current are both scalars; fluence is a vector indicating the

net number of neutrons per unit area over time.

The fission fragments are heavier and have lower potential energy than the original nucleus

Fission causes electrons to be stripped from atoms and energy is released when they recombine

The increase in the total number of nucleons after U-235 absorbs a neutron results in a more massive nucleus

The total binding energy of the fission products is higher than U-235 and the fission neutron

A focus on production over safety

Insufficient training of control room operators

Lack of proper emergency response plans

Failure to conduct regular safety inspections

Each neutron contributes to the temperature of the moderator

Flux only determines how fast neutrons move, not the power

Neutron flux governs the fission rate, which determines the amount of energy released
