- A paper study was conducted to determine the best method for fixing the /sup 14/C-contaminated CO/sub 2/ resulting from an HTGR fuel block burner as CaCO/sub 3/, and to determine the best methods for disposing of the CaCO/sub 3/ thus produced. The fixation method selected was the direct reaction of a Ca(OH)/sub 2/ slurry with the CO/sub 2/. The least expensive disposal options which are likely to be acceptable appear to be the shallow-land burial of either drummed CaCO/sub 3/ solid (total cost = $18.47/kg heavy metal) or drummed CaCO/sub 3/ concreted with cement (total cost = $43.33/kg heavy metal). Neither placing the CO/sub 2/ fixation process before the Kr removal process nor separating the bulk of the graphite fuel block from the fuel particles is attractive on both technical and economic grounds. However, reduction of the HTGR fuel nitrogen content appears to be a more attractive method of reducing the /sup 14/C release rate.
