heading toward the detector will begin life with a highly scattered thermal
spectrum and will have an inaccurate fast spectrum. If the dead zone length is
only 20 cm, we might imagine such rays writing to the detector tally within
their active lengths, despite their innaccurate estimate of the uncollided fast
their active lengths, despite their inaccurate estimate of the uncollided fast
angular flux. Thus, an inactive length of 100--200 cm would ensure that any such
rays would still be within their inactive regions, and only rays that have
actually traversed through the core (and thus have an accurate representation of
