Title: TRIBU, a 2-dimensional triangular mesh diffusion, burnup, and fuel management program

Technical Report ·
OSTI ID:4356043

From 1973 annual meeting of the Belgian section of the A. N. S.; Mol, Belgium (14 Jun 1973). The program TRIBU (TRIangular miesh with BUrnup) is designed for the detailed fuel cycle analyses of fast and thermal reactors with hexagonal assemblies. The triangular grid used for the diffusion and the depletion calculations corresponds to mesh sizes equal to the side, to half the side or to one third of the side of the fuel assemblies; the isotopic compositions are computed at each point of this grid (7, 19 or 37 points/ assembly), and the flux distributions are obtained taking into account different isotopic compositions in each sixth of the assemblies, and different axial bucklings per assembly. To the burnup chains (/sup 232/Th-/sup 234/U and /sup 235/U--/sup 236/U, /sup 238/U--/sup 242/Pu) cor respond two separate sets of fission products (rapidly saturating, slowly saturating' non-saturating) as well as /sup 135/Xe, /sup 149/Sm and /sup 241/Am production. The depletion of burnable poisons (boron and samarium) is also computed. (auth)
