OSTI ID:4824150
A semi-empirical method for calculating material bucklings for slightly enriched uranium tubes in light water is presented. Lattice parameters were calculated by the IDIOT code. Buckling was calculated by the one group critical equation, using an adjusted regeneration factor (eta) to obtain a correlation to measured values. Measured bucklings on tube lattices at 0.95, 1.0, 1.25, 1.44, 1.47, and 1.6% /sup 235/ were used in the correlation. The calculated and measured maximum bucklings at these enrichments agreed to within plus or minus 350 10/sup -6/ cm/sup -2/. A curve of adjusted eta versus /sup 235/ enrichment is given. The reliability of the method is limited to the range of tube sizes and U/sup 235/ enrichments used in the correlation. Beyond this range, the method is less reliable, but useful for lattice survey studies. (auth)
