Title: Robotics development at TMI-2

A remote reconnaissance vehicle (RRV) was initially developed to visually and radiologically survey the Three Mile Island Unit 2 (TMI-2) reactor building basement, which is not accessible to workers because radiation levels are extremely high (i.e., 10 to 1000 R/h). By mid-1985, the RRV had completed surveillance and sludge sampling missions that demonstrated its utility and suggested that the RRV could be modified to perform more aggressive sampling and decontamination work. This paper discusses the design criteria and operational experiences that GPU Nuclear Corporation (GPUNC) has had with expanding the use of the RRV to take concrete core bores, perform gross flushes, and remove sediment from the reactor building basement. The basic RRV unit is shown. This six-wheeled vehicle weighs approx.224 kg (600 lb) and is powered by two 1/2-hp motors. Its power, control signals, and video transmissions pass through a thin-layered cable that winds around a reel located on the RRV.
