Patent Number: H00009202
Section: claims

1. Method for the removal of radioactive cesium from a vapor stream which comprises: (a) passing an input vapor stream containing radioactive cesium into a bed of silicate glass particles at a temperature of at least about 700.degree. F.;  (b) chemically incorporating at least a portion of the radioactive cesium in said silicate glass particles; and  (c) withdrawing an output vapor stream containing a reduced content of radioactive cesium from said bed.  (a) passing input steam containing radioactive cesium into a bed of silicate glass particles;  (b) chemically incorporating at least a portion of the radioactive cesium in said silicate glass particles at a temperature of at least about 700.degree. F.; and  (c) withdrawing output steam containing a reduced content of radioactive cesium from said bed. 2. Method according to claim wherein the temperature of the vapor and the bed of silicate glass particles is at least about 800.degree. F. 3. Method according to claim 2 wherein the silicate glass particles comprise borosilicate glass. 4. Method according to claim 3 wherein the glass particles are in the form of spheres. 5. Method according to claim 1 wherein the silicate glass particles comprise borosilicate glass. 6. Method according to claim 5 wherein the glass particles are in the form of spheres. 7. Method according to claim 1 wherein the cesium forms a stable silicate by combining with silica in the glass. 8. Method according to claim 1 wherein said cesium is present in said vapor in a form selected from the group consisting of CsI, CsOH, and mixtures thereof. 9. Method for the removal of radioactive cesium from steam which comprises: 10. Method according to claim 9 wherein the temperature of the steam and the bed of silicate glass particles is at least about 800.degree. F. 11. Method according to claim 10 wherein the silicate glass particles comprise borosilicate glass. 12. Method according to claim 11 wherein the glass particles are in the form of spheres. 13. Method according to claim 9 wherein the silicate glass particles comprise borosilicate glass. 14. Method according to claim 15 wherein the glass particles are in the form of spheres. 15. Method according to claim 9 wherein the cesium forms a stable silicate by combining with silica in the glass. 16. Method according to claim 9 wherein said cesium is present in said steam in a form selected from the group consisting of CsI, CsOH, and mixtures thereof.
