Comparison of binding energy to the sorption enthalpy of radionuclides with trap materials used in LMFBRs

In liquid metal fast breeder reactors (LMFBR), traps are provided in the primary coolant circuit to reduce the contamination due to the deposition of long lived γ-emitting nuclides. The binding energies of the radionuclides with iron and nickel were estimated using Pauling’s electronegativity. The results are comparable to the sorption enthalpies derived from the experimental isotherms.
