【 摘 要 】

The objective of this document is to provide traceability and justification for a select few new geochemical data used in the Special Analysis entitled 'Special Analysis for the Dose Assessment of the Final Inventories in Center Slit Trenches One through Five'. Most values used in the Special Analysis came from the traditional geochemical data package, however, some recent laboratory measurements have made it possible to estimate barium K{sub d} values. Additionally, some recent calculations were made to estimate neptunium K{sub d} values as a function of pH. The assumptions, justifications, and calculations needed to generate these new values are presented in this document, and the values are summarized.
