Two energy-group eleven-region constants are prepared for the single cylindrical core of Kyoto University Critical Assembly (KUCA) loaded with uranium fuel of fourty-five per cent enrichment. The procedure is based on the twenty-six-group microscopic cross section libraries MGCL26GR and SMF26GR as its starting point, and on the flux calculations by one-dimensional transport theory code ANISN-JR. Cross sections are averaged with these flux as weighting functions. Although the constants do not produce a complete agreement with experiment when used for criticality calculation, we give them here as a form of an interim report. For the various analyses of the experiment being conducted at KUCA, a relatively simple form of constants are needed, which is the reason for this presentation. Because of its complicated fuel-region geometry, repeated spectrum calculations are required. The report spends a large portion to describe such procedure.
