Tank selection criteria and retrieval recommendations for Tri-Party Agreement milestone M-07
Between 1943 and 1964, 149 SSTs were built for the storage of high-level liquid radioactive wastes at the Hanford Site. These SSTs are located in 12 tank farms of 4 to 18 tanks each in the 200 East and 200 West Areas on the Hanford Site (see Figure 1). No wastes have been added to any of these tanks since November 1980. A total of 67 of the SSTs are now known or suspected leakers. Pumpable interstitial liquid and supernate wastes have been removed from 105 SSTs and transferred to double-shell tanks (DST) in a jet pumping program. The 28 DSTs are a tank-in-tank design and were placed in service beginning in 1971. In accordance with Public Law 101-510, Section 3137 (the Wyden Amendment), a total of 53 tanks (48 SSTs and 5 DSTS) have been identified by the US Department of Energy (DOE) as having potential for releases of high-level waste due to uncontrolled increases in temperature or pressure. These tanks have been designated as watch list'' tanks by DOE. The Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement) (Ecology et al. 1990) interim milestone M-07-01 states Submit tank selection criteria, retrieval options and recommended tank selection to Ecology for concurrence.'' This document provides the applicable criteria, discusses the various retrieval options available, and recommends a single-shell tank (SST) for demonstration of SST retrieval technology.
