Abstract
During operation of sodium cooled fast reactors in the absence of fuel pin failure, the radionuclides of radiological concern are 54Mn, 60Co, 58Co and 65Zn which cause activity burden during maintenance of primary components. Experiments were carried out towards development of radionuclide trap using nickel foam and foil which serves as a single trap material to scavenge all the above radionuclides simultaneously in flowing sodium system at various temperatures and duration of time. The uptake behavior of the trap materials at various experimental conditions was estimated using Atomic Absorption Spectroscopy.
