註釋

Effects of fuel plates successively withdrawn from the center fuel element of a seven-by-three core loading at the Oak Ridge Bulk Shielding Facility were evaluated by two-dimensional two-group diffusion calculations performed on the NASA reactor simulator. Two calculation methods were used: (1) The slowing-down properties of the experimental fuel element were represented by infinite media parameters; and (2) the finite size of the experimental fuel element was recognized, and the slowing-down properties of the surrounding core were attributed to this small region. Reasonable agreement existed between experimental and calculated effects.
