3. NATURE OF PHYSICAL PROBLEM SOLVED

FURNACEJ is a two-dimensional diffusion-burnup code for use in the detailed burnup analysis of fast reactors. The code is an extension code of the FURNACE. There exists no essential difference between FURNACE and FURNACEJ. However, the latter can deal with JAERI-Fast-Set as its cross section library, while the former is designed to use ABBN set. Additionally, in FURNACEJ, group-dependent and -independent transverse bucklings of each region can be computed and punched on cards, if desired. This is prepared for users so as to use them as input data for detailed two-dimensional x-y calculations.

6. TYPICAL RUNNING TIME

A straight Keff calculation in r-z geometry with (27 x 36) space points, 6 energy groups, 19 regions and 8 mixtures requires 260 sec running time on the CDC 6600. If the same  problem is carried out over the burnup stage of the code, the running time is 1025 sec for four burnup steps including the initial time step.
