| description | An experimental device for plasma treatment of low and intermediate level
radioactive waste was built and tested in several design variations. The
laboratory device is designed with the intention to study the general effects
and difficulties in a plasma incineration set-up for the further future
development of a larger scale pilot plant. The key part of the device
consists of a novel microwave plasma torch driven by 200 W electric power,
and operating at atmospheric pressure. It is a specific design characteristic
of the torch that a high peak temperature can be reached with a low power
input compared to other plasma torches. Experiments have been carried out to
analyze the effect of the plasma on materials typical for operational
low-level wastes. In some preliminary cold tests the behavior of stable
volatile species e. g., caesium was investigated by TXRF measurements of
material collected from the oven walls and the filtered off-gas. The results
help in improving and scaling up the existing design and in understanding the
effects for a pilot plant, especially for the off-gas collection and
treatment. |
