Abstract
Primary components of sodium cooled fast reactors get contaminated due to activity transport that occurs from core to out-of-core through coolant which causes activity burden to the personnel during operation and maintenance. To minimize the MAN-REM issues it is necessary to scavenge 54Mn, 60Co and 65Zn which are of major radiological concern from primary sodium using a compact device. Experimental studies were performed at various durations and temperatures with nickel as single trap material to trap the radionuclides simultaneously and its uptake was estimated. Trap** efficiency of porous and non-porous Ni at 773 K was estimated using radiotracer technique.
