Fiscal year 1992 program plan for evaluation of ferrocyanide in the Hanford Site waste tanks. Revision 2
The purpose of this document is to provide a description of the fiscal year (FY) 1992 priorities, logic, work breakdown structure (WBS), and task descriptions for the Ferrocyanide Waste Tank Safety Program. The Ferrocyanide Safety Program was established in 1990 to provide resolution of a major safety issue identified for 24 high-level waste tanks at the Hanford Site. Radioactive wastes from defense operations have accumulated at the Hanford Site in underground waste tanks since the early 1940s. During the 1950s, additional tank disposal space was required to support the defense mission. Two procedures were used to obtain this additional volume within a short period of time while minimizing the construction of additional tanks. One procedure involved the use of evaporators to concentrate the waste by removing water. The second procedure involved a process for scavenging radiocesium from tank waste liquids and pumping the resulting liquids to disposal cribs. In implementing this process, approximately 140 metric tons of ferrocyanide were added to wastes that were later routed to 24 single-shell tanks.
