Abstract

During the years 1983 and 1984 the FLK-60 high temperature slagging incinerator at Mol was used for incineration of simulated plutonium waste and BWR power station waste after extensive technical adaptations. A total of 10 tons of simulated waste containing 15 g of plutonium and 6 tons of simulated waste containing 624 MBq of 60-Co and 393 MBq of cesium isotopes was successfully treated. The average volume reduction factor was 18. Global decontamination factors of 280 000 for 137-Cs and 22 000 000 for 239-Pu were measured. Routine working and interventions for maintenance and repair could be carried out safely in alpha conditions. The report describes in detail the technical adaptations and the behaviour of the various parts of the installation during the 39 runs carried out in the contract period. It also gives the chemical and radiochemical composition of the granules and secondary waste streams. The plutonium-based leach rate of the granules is in the range of 2 x 10**-5 to 3.5 x 10**-4 g/cm**2. Finally typical mass, energy and radioactivity balances of the installation are given and various options for the final conditioning of the granules are briefly discussed.
