COMPARISON OF ONE- AND TWO-DIMENSIONAL MULTIGROUP CALCULATIONS FOR THE APDA FAST BREEDER REACTOR
Technical Report
·
OSTI ID:4282534
The results of a one-dimensional spherical multigroup calculation and a two-dimensional cylindrical multigroup calculation are compared. When correctlons are made for the different amounts of poison used in the two problems the values of k agree within 1%. The reactivity coefficient of a change in core volume derived from the two-dimensional calculation results agrees to ~ 10% with a similar coefficient derived from onedimensional results. Power and flux patterns from the two calculations are also compared, and agreement between the two sets of results is shown in the mirror plane in the two-dimensional problem where axial components of the flux gradient are zero.
