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. Trapping efficiency of porous and non-porous Ni at 773 K was estimated using radiotracer technique.
