Demonstration Information

Technology Name: Dual Arm Work Platform Teleoperated Robotics System

Demonstration Name:Dismantle Graphite and Boral | Demonstrated on: 6/1/1997
Demonstration Site: Chicago Pile-5 Reactor

Demo Objective

The DAWP removed 5300 lbs of graphite blocks, 1400 lbs of lead sheeting, 620 lbs of boral, and 2000 lbs of carbon steel Untorqued and removed 26 out of the 36 carbon steel studs that were installed in the reactor tank's top flange Size reduced and dismantled a significant portion of the aluminum reactor tank (following approximately 200 linear feet of cuts through 3/8 - 3/4 in aluminum plating), and removed the resultant 600 lbs of aluminum plate from the reactor tank assembly. By using this remote system, conservatively speaking, approximately 15 person-rem of exposure was saved

Demo Results

The DAWP was very successful in meeting most of the stated objectives. The DAWP was successful in the three areas of the demonstration, including Showcasing DAWP­Ýs to dismantle and remove the reactor vessel, graphite, and miscellaneous low level waste from the reactor Working in conjunction with Rosie, a mobile teleoperated robot, to move radioactive materials from the reactor assembly to a staging area using a specially designed steel transfer can And performing remote miscellaneous tasks (i.e., size reduction of activated material, removal of bolts, etc) that the DAWP was not necessarily designed to do, but for which remote operations were required.
