摘要： The present invention relates to a method of capturing radioactive species in an aqueous solution and removing the radioactive species for disposal. The method includes the steps of providing a macroporous bead form sequestration resin, subjecting the bead form sequestration resin to radioactive species contained in the aqueous solution to allow the bead form sequestration resin to capture the radioactive species; and disposing the radioactive species in a radioactive storage facility.

摘要： A method for the cleanup of ionic species such as cobalt and nickel in nuclear power plant aqueous streams using a sequestration resin material is disclosed herein. The method includes the steps of providing a sequestration resin for removal of radioisotopes of transition metal impurities contained in the plant process streams, and distributing the sequestration resin into the plant process streams such that the sequestration resin interacts with the process streams and removes the transition metal impurities.

摘要： The oxidizing chemistry environment of BWR reactor water is a key factor promoting intergranular stress corrosion cracking of stainless steel and nickel based alloys used in reactor coolant system piping and vessel internals. This is typically mitigated during power operation with hydrogen injection. However, this method is only effective when the reactors are at power. Accordingly, this invention proposes a method of reducing electrochemical corrosion potential during the start-up phase of BWR reactors. The method includes the steps of providing a mitigation additive adapted to reduce electrochemical corrosion of a BWR reactor; and injecting the mitigation additive into the BWR reactor at a predetermined location prior to hydrogen injection coming online.
