METHOD FOR MONITORING THE CONDITION OF SHELLS OF HEAT-DRIVING ELEMENTS OF A NUCLEAR REACTOR WITH WATER HEAT CARRIER

摘要

The method of monitoring the state of the fuel element claddings of a nuclear reactor with a water coolant, including determining the concentration of fission products such as iodine isotopes and radioactive noble gases in the primary coolant flow and comparing the results of measuring the concentration of iodine and radioactive noble gases, characterized in that representativeness and accuracy of control, the flow of coolant is passed through a cation column, then divided into two parts, one of which is sent to an anion exchange column for the deposition of radioactive isotopes of iodine, then determine the concentration of radioactive noble gases in this part of the stream, the second part is sent to the degasser for the selection of radioactive noble gases and after degassing determine the concentration of radioactive isotopes of iodine.
