Waste characterization plan for the Hanford Site single-shell tanks. Revision 1.

摘要

The Waste Characterization Plan for the Hanford Site Single-Shell Tanks (WCP) describes the initial phase of the two-phase plan to characterize the defense wastes stored in single-shell tanks (SST) on the Hanford Site. The WCP represents an all-purpose plan to identify sampling and analysis requirements for regulatory, performance assessment, and technology and process development purposes. Descriptions of SSTs and the wastes are summarized in the WCP. Procedures for sampling and analyzing the waste for chemical, radiochemical, physical, and waste characteristic parameters are described. Rationale for the selection of parameters and for the use of procedures different than standard methods are discussed. Quality assurance and development activities to support this sampling and analysis effort are described in appendices to the WCP. The first phase of the WCP includes a reference sampling plan that will be used to evaluate laboratory systems, estimate sampling and analysis errors, evaluate vertical distribution of key waste components, determine potential bias in results caused by sampling from existing risers, and estimate tank constituent inventories. 32 refs., 13 figs., 23 tabs.
