Assessment of potential worker exposure during the operational phase of the Tumulus Disposal Demonstration Project
The Oak Ridge National Laboratory has a continuing commitment to improve waste management and storage practices for solid low level radioactive wastes (LLW). The Tumulus Disposal Demonstration Project was chosen by the Low Level Waste Disposal Development and Demonstration (LLWDDD) program as one of the disposal technologies that is being evaluated to dispose of this waste in an environmentally acceptable manner. For this project, primary waste packages containing dry, solid LLW with contact dose equivalent rates less than 200 millirem per hour were placed into secondary concrete disposal vaults and the void spaces filled with a concrete grout mix. The completed units were then placed on the Tumulus pad: To assess potential worker sequence for this disposal technology, the radiation field at the site was surveyed. Measurements of worker exposures during the loading operations necessary to prepare and to emplace the LLW were conducted. The goal is to develop a database sufficient to compare worker exposures for disposal facilities of different designs. 14 refs., 1 fig., 1 tab.
