Use Of Radioactive Iodine Evolved Into Reactor Cooling Water To Locate Defective Fuel Elements, Carl Mozel Stroud
Masters Theses
"The relative amount of radioactive iodine evolved in reactor cooling water by each fuel element provides an excellent indication of defective cladding on fuel elements. The radioactive iodine evolved into the reactor cooling water from a defective fuel element should be higher than the average radioactive iodine evolved by other fuel elements into the cooling water by an order of magnitude or more.
Radioactive iodine with non-radioactive iodine carrier is adsorbed on DOWEX SBR resin in the iodide form. The iodide is eluted from the resin with sodium hypochlorite and extracted into carbon tetrachloride. The iodine is reduced to iodide …
