Test Treatment of Fulfilled TBP - 12084
- SUE SIA 'Radon', Moscow (Russian Federation)
At SUE SIA 'Radon' were carried out investigations and treatment of spent TBP, containing uranium with the help of the following methods: - Impregnation of porous inorganic materials by spent TBP with the subsequent inclusion into the cement compound; - Spent TBP cementation together with other LRW (inclusion of spent TBP into cement compound was 2%); - inclusion of TBP into polymeric binder Nochar, Nochar, Pacific Nuclear Solutions, Indianapolis, USA; - Impregnation of industrial porous materials with the subsequent treatment at plasma incineration facility at temperature up to 1600 deg. C. In such case takes place pyrolysis process and after-burning of organic content of spent extractant, as well as melting of its mineral content together with porous material. As a result slag incorporating radionuclides and phosphorus compounds is formed. The slag has a high chemical stability. With the help of the first method has been received cement compound with the inclusion of 20 weight % of spent TBP and during the pilot treatment about 1 m3 of TBP has been solidified. Together with other LRW over then 10 m{sup 3} of TBP has been solidified at the stationary cementation facility. Spent TBP inclusion into the polymeric binding material Nochar (N) has been carried out under laboratory conditions with a mass ratio TBP / Nochar from 1 / 1 till 20 / 1. At the plasma incineration facility has been processed about 1 m{sup 3} of spent TBP. Comparative evaluation for the suggested methods of spent TBP treatment has been made. (authors)
