【 摘 要 】

The current flowsheet for the Am/Cm program requires that the glass pool be sparged with argon during the soaking period immediately prior to draining the melter. The effect of varying sparge rate and duration on the homogeneity of the final glass product was evaluated using the full scale 5-inch Cylindrical Induction Melter (CIM5) pilot facility. The tests showed that the homogeneity of the glass product is maintained provided the sparge rate is at least 1.5 scfh and the sparge duration is at least 45 minutes or the flowrate is at least 1.0 scfh and the sparge duration is 60 minutes. SRTC recommends that the melt pool be sparged for 75 minutes with an argon flowrate of 1.5 scfh and a sparge dip tube located 1-inch from the melter bottom. In addition, pour flowrate was found to be a reliable indication of glass homogeneity.
