“…Economic feasibility of radionuclide trap as part of fuel subassembly was also investigated [5]. As it is known that without some means to lower the radiation level near a fast reactor heat transport system, maintenance difficulties could create an operational burden that could be difficult to avoid without costly remote equipment.…”

In the absence of fuel pin failure, major radiation burden in primary heat transport system of a sodium cooled fast reactor is due to long-lived and high gamma active corrosion products 54 Mn, 60 Co and 58 Co. For minimizing the radiation burden to operation and maintenance personnel, radionuclide traps are essential to concentrate and contain these radionuclides in a particular location of primary system. To remove activated corrosion products from primary sodium, use of nickel foam as radionuclide trap material has been proposed as a candidate trap material for fast reactors as against the use of nickel in form of rolled sheet and pall rings. This paper describes about the effectiveness of nickel foam for trapping manganese and cobalt from liquid sodium.
