Radiation hardened telerobotic dismantling system: A proposal for remediating the UKRITYE encasement at the Chernobyl NPP

摘要

A major problem facing those charged with reclaiming the UKRITIYE encasement is the dismembering and removal of the fuel containing masses (FCMs). Due to the intense radiation fields involved, the work must be controlled remotely, so as to minimize exposure to humans. Radiation also quickly damages key components of conventional robots, and thus a successful design must eliminate these vulnerabilities. The authors propose to design and construct a robotic knife to cut through obstructions and reactor debris, including FCMs. To withstand the severe radiation fields typical of high level waste, the robotic system will not rely on electrical motors or actuators, but will utilize pneumatic power for its manipulating and control functions.
