TREATMENT SEPARATION AND RECOVERY TRANSURANIC ELEMENTS FROM LIQUID WASTES PRODUCED BY PLUTONIUM PLANT OF CRE CASACCIA

Objective

THE LIQUID WASTES PRODUCED BY CASACCIA PLUTONIUM PLANT, DUE TO THE CONTENT IN ALPHA EMITTERS, MUST BE CONSIDERED, ACCORDING TO THE PRESENT NATIONAL REGULATION (GUIDA TECNICA N 26 ENEA DISP) AS INCLUDED IN "CATEGORY 3" HIGHEST RISK WASTES.
THE MAIN PURPOSE OF THE RESEARCH WORK RELATED TO THIS CONTRACT IS TO STUDY AND DEVELOP IN LABORATORY AND PRE-PILOT SCALE A GENERAL PURPOSE TRANSURANIC ELEMENT EXTRACTION AND RECOVERY PROCESS.
TO IMPLEMENT THIS PROCESS, THE SELECTED EXTRADING AGENT IS THE OCTYL (PHENYL) N N DIISOBUTYLCARBAMOYLMETHYLPHOSPHINE OXIDE (CMPO)
THE STUDY UNDER THIS CONTRACT WILL PERMIT TO VERIFY
THE FEASIBILITY OF A SIMULTANEOUS SEPARATION OF U, PU AND AM FROM LIQUID WASTES OF DIFFERENT COMPOSITION WITH A SINGLE EXTRACTION PROCEDURES THE FLEXIBILITY OF THE PROCESS;
THE EASINESS OF MANAGEMENT OF THE PROCESS;
THE RECOVERY OF ACTINIDES IN A SUITABLE FORM TO ALLOW THEIR REWORK;
THE VOLUME REDUCTION MINIMIZING THE PRODUCTION OF SECONDARY WASTES.

B.1. IDENTIFICATION AND CLASSIGICATION OF LIQUID WASTES TO BE TREATED
B.2. PROCUREMENT OF THE CMPO EXTRACTANT
B.3. PURIFICATION OF CMPO, AND PURITY EVALUATION TEST
B.4. PREPARATION OF SIMULATED WASTES AND INTERACTION STUDIES WITH THE SOLVENT
B.5. CHOICE OF DILUENT
B.6. DECONTAMINATION TESTS AT LABORATORY SCALE WITH REAL SOLUTIONS
B.7. MODELLING OF THE FLOWSHEET
B.8. PRE-PILOT SCALE TESTS WITH REAL SOLUTIONS
