PULSED EDDY CURRENT INSTRUMENT FOR MEASURING SODIUM LEVELS OF EBR-II FUEL RODS
A pulsed eddy current system with differential coil assembly was proved to be applicable to measure the sodium levels in EBR-II fuel rods with an accuracy better than plus or minus 0.030 in. When the sodium levels are flat or have only slight variations, a cylindrical coil system can be readily used. However, when the sodium levels vary around the periphery, the cylindrical system fails to measure the average sodium levels. A four-channel point-probe-type pulsed eddy current system was developed for this problem. With this equipment the sodium levels at four points on the periphery could be determined. The average value of these four measurements correlated with those determined by destructive tests. (M.C.G.)
