摘要：A method of stabilizing nuclear material is disclosed. Oxides or halides ofactinides and/or transuranics (TRUS) and/or hydrocarbons and/or acids contaminatedwith actinides and/or TRUs are treated by adjusting the pH of the nuclear material to notless than about 5 and adding sufficient MgO to convert fluorides present to MgF: aluminais added in an amount sufficient to absorb substantially all hydrocarbon liquid present,after which a binder including MgO and KHPOis added to the treated nuclear material toform a slurry. Additional MgO may be added. A crystalline radioactive material is alsodisclosed having a binder of the reaction product of calcined MgO and KHPOand aradioactive material of the oxides and/or halides of actinides and/or transuranics (TRUs).Acids contaminated with actinides and/or TRUs, and/or actinides and/or TRUs with orwithout oils and/or greases may be encapsulated and stabilized by the binder.
