MEASUREMENTS AND ANALYSIS OF URANIUM-D$sub 2$O LATTICES
A series of exponential measurements performed on uranium-heavy water lattices is summarized. Three enrichments of fuel materials were used: 0.49, 0.71 (natural), and 0.90 wt.% U/sup 235/. The uranium fuel slugs ranged from 0.75 to 2 in. in diameter and were encased in tubes of 0.40-in. aluminum. The lattice cell spacings varied from 3 to 12 in. The analysis of the data is divided into two parts. The first part deals directly with the neutron flux measurements and reports for each lattice, the material buckling (B/sup 2/, a pair of disadvantage factors (F and F/sub m/), and a flux ratio (R). The second part of the analysis is concerned with the long-range problem of improving reactor calculations. Attempts were made to correlate the measurements with themselves and with other nuclear measurements so as to obtain a consistent formalism for computing uranium -heavy water reactor parameters.
