Pyroprocessing is a high- temperature electrochemical methode originally developed for treating spent nuclear fuel. It is now being adapted for intriment waste. In this process, waste materials are disolved in a molten salt electrolte (e.g., LiCl- KCl) at 500- 700 ° C.

Radiation Shielding

Because of it high density (19.1 g / cm ³) and atomic number, DU is an excellent gamma radiation shield. It is es used in medical radiation therapy rooms, transport cass for radioactive materials, and container storage facilities. Recycled DU can be cast machined into shielding blocks, offering a cost- effective contativa to lead. Proper encapsulation ensures radioactive emissions emissions effin with regulative limits.
