phi is the number of fissions per initial fissile atoms. tinf is t = inf, setting it 1.0E+13. R(theR) is the nuber of U-239 atoms produced per fission. lamda1 is decay constant for U239 and Np239. lamda2 is decay constant for Np239. theEU239 is average energy from decay of on U239 atom (0.474 MeV) theENp239 is average energy from decay of on Np239 atom (0.419 MeV)
