P&t, английский Partitioning and transmutation. partitioning is the separation of undesirable long-lived radioactive elements such as minor actinides (e.g. americium-243) and fission products from spent fuel. transmutation is the transformation of these undesirable elements into short-lived or stable elements using nuclear reactions. together these processes would, at least partially, eliminate those parts of high-level waste that contribute most to its heat generation and long-lived radioactivity. p&t therefore has the potential to reduce the time that waste needs to be kept isolated from several thousand to several hundreds of years. nea work on p&t
