This Supporting Document analyzes a proposal for reducing the under-packager volume to decrease the amount of fissile material that could accumulate there. The analysis shows that restricting the under packager volume to no more than 4080 in{sup 3} will assure that if accumulated fissile material beneath the packager is added to the worst-case mass of fissile material in the discharge chute, a k{sub eff} of 0.98 will not be exceeded.
