Objective
THE INCINERATION IS PRESENTLY CONSIDERED A VERY GOOD WAY TO OBTAIN STRONG VOLUME REDUCTIONS OF INTERMEDIATE AND LOW ACTIVITY SOLID RADWASTES OBTAINING AT THE SAME TIME A PRODUCT APPARENTLY EASY TO BE CONDITIONED. IN SOME CASES NEVERTHELESS THE ASH SOLIDIFICATION CAN GIVE IN THE PRACTICE SOME PROBLEMS: THIS WAS ASCERTAINED, FOR EXAMPLE, DURING THE CEMENTATION OF THE ASHES COMING FROM THE INCINERATION OF THE CAORSO RADWASTES AT STUDSVIK (SWEDEN). IT WAS OBSERVED THERE IN FACT A MORTAR SWELLING DURING THE CEMENT SETTING PHASE AND MOREOVER AN AMMONIA EVOLUTION WAS NOTICED. BECAUSE OF THIS STRONG SWELLING PRODUCED IN THE CASE MENTIONED BEFORE THE MORTAR WENT OUT OF THE DRUMS AND THE SOLIDIFIED PRODUCT WAS VERY POROUS. SIMILAR PROBLEMS ARE REPORTED TO HAVE BEEN MET IN OTHER NUCLEAR PLANTS.
SO THIS RESEARCH CONTRACT AIMS TO INVESTIGATE ABOUT THE REASONS OF THESE PHENOMENA BY MEANS OF A PHYSICO-CHEMICAL CHARACTERIZATION OF THE MENTIONED ASHES WITH THE OBJECTIVE TO DEFINE THE BEST WASTE/CEMENT MIXTURES WITH RESPECT TO THE MECHANICAL AND LEACHING RESISTANCE PROPERTIES.
1. ASH SELECTION AND SUPPLYING.
2. ASH CHARACTERIZATION BY:
- AA METAL ANALYSIS
- NITRIC, ORGANIC AND AMMONIACAL NITROGEN CONTENT
- GAMMA SPECTROSCOPY RADIOCHEMICAL ANALYSIS
- TAP DENSITY
- ASH PARTICLE SIZE
3. ASH CEMENTATION AT 1/2, 1/3, 1/4 ASH/CEMENT RATIO.
4. SAMPLES CHARACTERIZATION BY MECHANICAL STRENGTH, SETTING TIME, THERMAL EVOLUTION. DEPENDING ON THE FIRST RESULTS OBTAINED THE PROGRAMME WILL BE CONTINUED ACCORDINGLY, IF THE CASE OPERATING SOME ASH PRETREATMENT. BEST COMPOSITION SELECTION.
5. BEST COMPOSITION CHARACTERIZATION BY THE ISO 6961-82 LONG TERM LEACH TEST.
