The Waste Package Closure System, for the closure of radioactive waste in canisters for permanent storage of spent nuclear fuel (SNF) and high-level waste in the Yucca Mountain Repository, was designed, fabricated, and successfully demonstrated at the Idaho National Laboratory. This paper focuses on the robotic hardware and tools necessary to remotely weld and inspect the closure lid welds. The system was operated remotely and designed for use in a radiation field due to the SNF contained in the waste packages being closed.
