Engineering Considerations for Remote Refabrication of EBR-II Fuel Elements
The development of remote-control methods for manufacturing EBR-II fuel elements is influenced by many interacting factors. Radiation levels within the process cell are predicted to range from 103 to 107 rad per hour. Radiation damage to organic lubricant, electrical insulations, elastic seals, and protective coatings precludes the use of many standard machine components. Heat generated in the fuel by absorbed radiation makes forced cooling necessary in many operations. Oxygen must be excluded from all operations in which the fuel is exposed. Equipment must be designed for remote maintenance and component replacement within the limitation of available manipulators. The EBR-II fuel consists of fissium alloy pins, sodium-bonded in stainless steel tubes. Precision casting is chosen as the basis for refabricating the fuel pins. Remote- control equipment is developed to cast, assemble, and inspect the EBR-II fuel elements. Radiation resistant, plug-in machine components are developed to give reasonable life expectancy and to allow remote maintenance and replacement.
