# Suppose that the thermal ux in a nuclear fuel rod is 1 × 1014 neutrons/cm2/s and the fast ux is 2 ×.

Suppose that the eager ux in a nuclear fuel rod is 1 × 1014 neutrons/cm2/s and the secure ux is 2 × 1014 neutrons/ cm2/s. What is the total neutron ux in the fuel rod?

Using homely pure mechanics, demonstration that a eager neutron after a while a most presumable kinetic life of 0.025 eV has an mean velocity of closely 2200 m/s in a nuclear fuel rod.
