to the thermal-energy range and are absorbed in
the fuel = Npf (6)
Show that the four-factor formula can also be derived by starting at any of the different points in the cycle, i.e., starting from p, f, or .
p 0.906, and that they change very little (< 1 part per thousand, i.e., < 1 mk) with fuel burnup (or irradiation). This is understandable since and p originate with U-238, and the U-238 fraction in the fuel changes very little.
