Claim:
1. A method for clean-up of radioactivity in a reactor coolant contained in a nuclear power plant, comprising the steps of: (a) providing a sequestration resin for removal of radioisotopes of transition metal impurities contained in a reactor coolant system of a nuclear power reactor, the sequestration resin comprising linear multi-amine ligand sites covalently coupled to a sulfonic acid-based polymer resin by a sulfonamide linkage, wherein the linear multi-amine ligand sites are coupled to the sulfonic acid-based polymer resin in a configuration in which lone pair electrons of nitrogen exist on the ligand sites, such that the resultant sequestration resin is capable of complexation of transition metal cations by uncharged organo-metallic complexation; and (b) distributing the sequestration resin into a clean-up system for reactor coolant contained in the reactor coolant system such that the sequestration resin complexes the radioisotopes using the lone nitrogen electron pairs, so as to remove the radioisotopes from the coolant.
