Abstract

TO STUDY THE DISPERSION OF PLUTONIUM BEARING AEROSOLS DURING GLOVE BOX FIRES ON A FULL-SIZE LABORATORY SCALE, A SPECIAL FIRE-CHAMBER SIMULATING A PLUTONIUM HANDLING FACILITY AND EQUIPPED WITH THE NECESSARY ANALYTICAL INSTRUMENTATION WAS DEVELOPED. FOR COMPARATIVE FIRE STUDIES, A 0.6MW FIRE SOURCE WAS STANDARDISED, WITH A REPRODUCIBILITY BETTER THAN 10%. PMMA (A MAJOR GLOVE BOX CONSTRUCTION MATERIAL) WAS USED AS COMBUSTIBLE MATERIAL FOR THIS STANDARD FIRE, TO WHICH, IF REQUIRED, SAMPLES OF OTHER CONSTRUCTION MATERIALS COULD BE ADDED. USING CERIUM-EUROPIUM OXIDE AS A SUBSTITUTE FOR PLUTONIUM OXIDE FOR SURFACE CONTAMINATION OF THE MATERIAL, THE PERCENTAGES OF THE AIRBORNE CONTAMINATION CARRIED AWAY WITH THE COMBUSTION GASES AND REMAINING INSIDE THE FIRE CHAMBER AFTER A STANDARD FIRE, WERE MEASURED. DURING THE FIRE, BETWEEN 60 AND 75% OF THE ORIGINAL CONTAMINANT LANTHANIDE OXIDE BECAME AIRBORNE, 1-2% WERE CARRIED AWAY WITH THE COMBUSTION GASES INTO THE VENTILATION OUTLET.
