Infrared scanner parametric test using heated simulant tank waste

摘要

An infrared (IR) scanner device has been developed which provides a means of determining the variation in surface temperature throughout the waste surface area in ferrocyanide tanks, or other heat generating high level waste tanks. This report describes an experimental mockup test performed in a pit area of the an experimental building. The mockup duplicated the geometric factors and approximated the tank gas space conditions which are anticipated in the heat generating waste tanks. The waste surface temperature magnitudes in these tanks are estimated to range from 70 to 120 (degrees)F. The experiments described in this report addressed a lower range of anticipated waste surface temperature below 100 (degree)F by employing test tables of heated simulant. The experiments were conservative in that the IR instrument was evaluated in a lower temperature range that is more challenging to the IR detector sensitivity. The IR scanner temperature indications were compared with simulant waste temperatures measured by emplaced thermocouples.
