Use of a Thermal Probe to Determine the Effective Thermal Conductivity of Packaging Contents.

摘要

The thermal conductivity of simulated CH-TRU waste was successfully measured at ambient conditions using the line source thermal conductivity probe technique. The ''atypical'' probe (i.e., larger in diameter) used for this application was successfully adapted to existing hardware and software. The portable automated instrumentation system is ideally suited for remote field experiments. Results of the experimental program indicate the line source thermal conductivity probe technique can provide a reliable, nondestructive, and easily implemented method for determining the thermal conductivity of actual CH-TRU waste. However, further experimental study is warranted to develop a disposable-piercing type of probe optimized for measuring the conductivity of CH-TRU waste at generating sites. 8 refs., 5 figs., 2 tabs.
