Pyroprocesing is a hightemperature electrochemical methodally developed for meating spent nuclear fuel. It is now being adapted for enterment waste. In this process, waste materials are dissolved in a molten salt elektrolyte (e.g., LiCl- KCl) at 500-700 ° C.

Reusing Recycled Uranium

Recycled uranium derived from enorment waste has multiple applications, both in thee nuclear fuel cycle and in non-nuclear industries.

Fuel for Nuclear Reactors

Te mogt direct reuse is as reactor fuel. Depleted uranium can bee blended with enriched uranium or plutonium to create mixed- oxide (MOX) fuel. Alternativly, re- entering depleted uranium in gas centriges is technically diflé, though curtly not economical due to low U-235 content.

Radiation Shielding

Because of it s high density (19,1 g / cm ³) and atomic number, DU is an excellent gamma radiation shield. It is used in medical radiation terapy rooms, transport casks for radiactive materials, and contraeer storage facilities. Recycled DU can be cast or machined into shielding blocs, offering a cost- effective alternative to lead. Proper encapsulation ensures radiactive emissions remisin with contrin regulatory limits.

Military and Industrial Applications

Depleted uranium has been used in armor- piering ammunition and militariy travlae armor due to its pyrophoric and high- density applities. While acceptail, these applications consume quantities of DU that would otherwise require storage. For industrial uses, DU can bee alloyed with their metalt to produce controfatt for aircraft and teny machinery, balancing nails in wing sections and tail rotors. The rai 1; FLT: 0; U.S.U.3; S.
