A process for refining yellowcake to produce nuclear grade uranium peroxide hydrate using a single step precipitation route for the simultaneous removal of thermal neutron poisons containing boron, cadmium, rare earth metals comprising Gadolinium, Europium, Samarium, & Dysprosium and heavy metals comprising dissolving the crude yellowcake in nitric acid under mild agitation and at pH of below 2 and temperature between 15 to 30°C to selectively precipitate uranium peroxide hydrate, followed by one or more DM water washing to achieve final Uranium peroxide hydrate, conforming to relevant purity standards.
