Modified TTA method for the determination of plutonium

Webb1 juni 2024 · Although uranium is mainly present in the form of uranyl in the spent fuel reprocessing, there are still some processes involving tetravalent uranium, such as using U (IV) to reduce Pu (IV) in plutonium uranium recovery by extraction (PUREX) process. It is necessary to carry out research work on extraction and separation of tetravalent uranium. Webb11 apr. 2024 · Fast reactors, including FBRs, extract more energy from used nuclear fuel and reduce waste by up to 80%. By employing techniques like pyroprocessing, scientists at the Argonne National Laboratory have developed ways to recycle used fuel without separating pure plutonium, thereby mitigating proliferation risks. Webbis the PUREX (Plutonium and Uranium Recovery by Extraction) process, which was originally developed to extract plutonium for producing nuclear weapons through a liquid-liquid extraction process. Uranium and plutonium are extracted independent of each other, leaving minor actinides and other fission products. In line plot histogram
