Assessment of potential worker exposure for the Tumulus Disposal Demonstration Project: Fiscal year 1988 annual report
The Tumulus Disposal Demonstration Project (TDDP) is evaluating the Tumulus technology for the disposal of solid low-level radioactive waste (LLW). The primary objective of the demonstration project is zero-release of radioactivity during the 100-year institutional control period of the facility. Radiological monitoring of the unit operations necessary for the preparation and placement of LLW onto the Tumulus pad was performed in order to determine the radiological exposures received by the workers as they disposed of this waste. These operations involved the placing of the primary waste containers into the secondary concrete disposal vaults, the grouting of these vaults, the sealing of the disposal containers, and the placing of the grouted vaults onto the Tumulus pad. Contact exposure rate measurements and transferable surface contamination levels were determined for the primary and secondary containers. The contact surface radiation levels were measured on all of the monitored primary waste disposal forms and had a dose equivalent rate of <200 mrem/hr (<2 mSv/hr).* This rate satisfies the requirement of the Waste Acceptance Criteria (WAC). 7 refs., 5 figs., 14 tabs.
