Extensive separations pretreatment alternative engineering data package for the Tank Waste Remediation System Environmental Impact Statement

This engineering data package provides supporting data for preparation of the TWRS Environmental Impact Statement (TWRS EIS). Data in this document addresses specifically the Extensive Separations Alternative. Engineering data packages addressing the other alternatives to be evaluated in the TWRS EIS are the No Disposal Action Alternative (WHC-SD-WM-EV-099), In Situ Disposal Alternative (WHC-SD-WM-EV-101), Tri-Party Agreement (WHC-SD-WM-EV-104), and the No Separations Alternative (WHC-SD-WM-EV-103). The Waste Retrieval and Transfer Engineering Data Package (WHC-SD-WM-EV-097) and the Closure Engineering Data Package (WHC-SD-WM-EV-107) provide additional data addressing the Tri-Party Agreement Alternative. Data provided in this document relate to impacts from construction, operations (including startup, and decontamination and decommissioning), resource operations (including startup, and decontamination and decommissioning), resource utilization, transportation, and radiation dose to workers. Processes and activities addressed in this data package include radionuclide removal, low-level waste vitrification, low-level waste disposal, high-level waste vitrification, on-site interim storage of the vitrified high-level waste product, and transportation of the vitrified high-level waste product to a geologic repository. Environmental Impacts associated with disposal of high-level waste in a geologic repository are not within the scope of the TWRS EIS and not addressed in this document, other than accounting for the repository disposal fee in order to equitably compare alternatives
