The objective of this project is to develop chemical reagents for the decontamination of nuclear power reactor coolant circuits with particular emphasis on PWR primary coolant circuits. These reagents must be effective at dissolving activated corrosion products, must be compatible with reactor coolant circuit materials and must be manageable in terms of radioactive waste disposal. A fundamental study of metal oxide dissolution has led to the development of low-oxidation-state transition-metal-ion (LOMI) reagents, which dissolve oxides rapidly without affecting the underlying metal. One of these reagents, vanadous picolinate/formate, has been used to decontaminate reactor specimens efficiently. The radiation-stability of this reagent is good, and the released activity can be collected conveniently on ion-exchange resins. Application of these types of reagents to PWR and BWR decontamination is outlined in the report.
