An evaluation was made of the filter efficiency of the N.S. Savannah in the case of a maximum credible accident (MCA), and took into account the reduction in filter efficiency caused by iodide forms other than elemental iodine. It is concluded that the present type BPL charcoal filter should be changed to a filter using an inorganic impregnant. Details are provided on: (1) the percentage of the iodine in the N.S. Savannah's Core that might be released as methyl iodide in the event of a MCA; (2) the means for improving the efficiency for trapping methyl iodide; (3) an evaluation of the N.S. Savannah's Safeguards System for the purpose of determining the two-hour exclusion zone; and (4) the biological uptake and retention of methyl iodide by humans.
