Resumo
The research and development program in reprocessing of low burn-up spent fuel elements began in
Brazil in 70’s, originating the lab -scale hot cell, known as CELESTE located at IPEN-CNEN/SP. The
program was ended at the beginning of 90’s and part of the radioactive waste generated mainly from the
analytical laboratories is stored at the Waste Management Laboratory. Among various types of radioactive
waste generated, the organic liquid represents a major problem for its management, because it can not be
directly solidified with cement. The objective of this work is to develop a pretreatment methodology to
degrade the ethyl acetate present in organic liquid waste so that it can subsequently be immobilized in
cement. This work was divided into two parts: i) selection and adaptation of three bacterial
communities for growth in medium containing ethyl acetate. ii) degradation experiments of ethyl
acetate present in radioactive organic liquid waste. The results showed that from bacterial communities
the highest biodegradation level observed was 77%.
