Robotic characterization of the elevation of the TMI-2 (Three Mile Island Unit 2) reactor building
The recovery of Three Mile Island Unit 2 required a determination and analysis of the major sources present in the basement. Since dose rates prohibited personnel entry into the basement, the necessary assessment of the basement conditions would require remote measurement techniques. One of the early analysis techniques was video inspection using small video cameras place in the basement through various penetrations. The next technique used remote survey instrumentation. One type of instrument used in the early surveys was the Eberline RO-7 high range ion chamber system, another being the Teletector type of Geiger-Muller detector. Strings of thermoluminescent dosimeters, known as TLD trees, also gained widespread use. The mobile platform provided was the remote reconnaissance vehicle (RRV), also known as Rover. This robot was designed for use in conducting surveys, decontamination, and video documentation in the reactor building basement. The results of the robotic survey efforts are reported to assist in understanding the basement status and to assist in planning for use of robotic surveying systems.
