Abstract

S/sub 2/, 1700-triangle, k/sub eff/ calculation of an EBR-II core requires about 4.4 minutes of CDC-7600 time; running times vary almost linearly with the total number of unknowns. Sources, fluxes, S/sub n/ constants, and cross sections may be read from standard interface files; flexible edit options are provided. Six scratch units and two system I/O units are required. A large bulk memory is necessary if core storage is inadequate. This program is operational on the CDC-7600, CDC-6600, and IBM- 360/195 computers. (13 figures, 13 tables) (RWR)
