TRU Waste Analysis and Preliminary Operating Parameters for a Radioactive Waste Slagging Pyrolysis Incinerator

摘要

The analysis of the TRU waste indicates that the approach of adding coal and bark to the TRU waste is recommended to provide a feedstock mixture chemically similar to refuse. This addition of coal and bark is not meant to imply that the TRU waste by itself cannot be processed, but rather, this addition minimizes the possibility of problems occurring with regard to the slagging of the inerts and ash contained in the TRU waste. The feedstock mixture is composed of 47% TRU waste, 33% bark, and 20% coal. The TRU waste in the feedstock is the desired 1675 kg/h processing rate, therefore, the equipment will be processing a total of 3563 kg/h of the feedstock mixture. The coal selected for add-mixing to the TRU waste is a high (4%) sulfur content coal. The bark selected is a douglas fir with an assumed 50% moisture content, on a wet basis. The gaseous flow rates and temperatures predicted for the processing of the feedstock mixture do not significantly deviate from those predicted for processing municipal refuse. The pollutant emissions, though different from the experience of refuse, are not expected to be extremely high. (ERA citation 04:021763)
