THE MULTI-GROUP ALBEDO METHOD
Technical Report

OSTI ID:4039166
A multi-group version is given of the albedo method for calculating the critical sizes of fast cores with moderating reflectors. Fairly accurate results for critical sizes were obtained for bare spheres snd cylinders of U/sup 2//sup 3/ /sup 5/ and Pu/sup 2//sup 3/>s9< s without the need to adjust the core cross- sections, as in the simple albedo method which uses one group in the core and two groups in the reflector. The multi-group albedo method, because of its simplicity, in suitable for calculations on the interaction of arrays of fissile cores. The method can be applied also to cores of awkward shape without any difficulty. (auth)
