Evaluation of Proposed New LLW Disposal Activity Disposal of LLW in an Engineered Trench rather than in Slit Trenches

[摘要] Following issuance of the original document (i.e., rev. 0), it was discovered that an error was made in stating the dimensions and volume of the Engineered Trench and the incorrect volume was used in calculating the concentration limits (i.e. the inventory limit divided by the volumetric waste capacity of the unit) in the tables. The terminology of calling the average concentrations ''limits'' proved problematic in managing the inventory limits through the deviation process. Since the average concentration values presented serve no essential purpose (Waste Acceptance Criteria are derived from the inventory limits), they were removed from the tables. Also, the name of the disposal unit was changed from the MegaTrench to the Engineered Trench. For clarification, a statement was added that differences in dimensions of disposal units of less than about 10 percent are inconsequential from a PA perspective.
