Flux distributions with typical rod and loading patterns
Side-to-side flux distributions calculated for ``rods out`` operation are compared to the normal equilibrium distributions. The results are highly sensitive to enrichment and flattening unbalance. Near side tube power limits are reached at total pile powers as low as 39%, and as high as 85% of the normal equilibrium. power. Calculations indicate that, with the current loading patterns, B, D, DR, F, H, and KW, theoretically could make rods out scram recoveries without exceeding tube power limits, whereas C and KE could not. Longitudinal flux profiles corresponding to possible control rod and mixing piece configurations are compared to the ideal cosine distribution. Peak fluxes for a given column power vary from 86 to 111 % of a cosine maximum. The position of the maximum flux varies from 115 cm (5.1 slugs) downstream to 131 cm (5.8 slugs) upstream of the center line of the slug column. The effects of non-uniform (front-to-rear) enrichment and flattening charges are not considered.
