Key Issues

Several waste types with unique chemical and physical properties

Tank safety issues

bull Limited waste characterization data

O 66 known or suspected leaking single-shell tanks

Tank Waste Pretreatment

Status - 25 5111192


Purpose Objective

Resolve tank safety issues by destroying organics and ferrocyanides

Minimize glass volume and disposal costs through efficient separation of radionuclides and inert material - Large fraction ( -90) of waste suitable for near

surface disposal (grout)

Small fraction ( - 1 0 ) requires disposal in geologic repository

Provide feed for vitrification and grout within allowable feed specifications

Status - 2 6 5 1 1 9 2


Scope

O Separation of radionuclides from all Hanford high-level tank wastes

O Development demonstration and construction of pretreatment processes and related facilities

Dissolution of soluble salts Removal of cesium and strontium TRU extraction Organic and ferrocyanide destruction

Safety and environmental analyses and permitting

Status

bull Disposal alternatives have been under investigation since 1970s

bull Priority being given to resolution of tank safety issues

Scoping studies initiated on ferrocyanide and organic destruction

Solids-liquid separation dissolution of soluble salts and cesium removal by ion exchange are generally proven technologies

Will result in high number of canisters separations for many waste types

without more advanced
