Selection Process for AX and A Farm Tanks

The four AX tanks and five A tanks (not including A-103) were selected under Consent Decree milestone B-2• Risk reduction• Curie count• Technetium-99 concentrations• Prior spill volumes

Hanford Tank Waste Operations Simulator modeling demonstrates these tanks can be retrieved within current double-shell tank (DST) Space Management program

Waste Receiver Facilities (WRF) are necessary to allow retrieval of other single-shell tanks (SSTs) in 200 East Area

Retrieval of SSTs in 200 West Area require one or more of the following• A WRF in 200 West Area• There are three DSTs in 200 West Area• Activation of the Cross Site Transfer Line Slurry Transfer Lines

Execution Strategy

Farm-wide approach

Full upgrade of infrastructure prior to initiation of retrieval

Deployment of two proven technologies at the start of retrieval

Simultaneous retrievals into a DST

Spares and redundant capabilities to increase operational performance

Use of alternate shifts to avoid heat stress hazards

Incorporation of lessons learned from C Farm retrieval

Rigorous risk evaluation and management plan

Enhanced Reach Sluicer Containment

Nozzle View of Enhanced Reach Sluicer

Elbow View for Enhanced Reach Sluicer

AX Farm Retrieval Technologies

All tanks in AX Farm are classified as sound

Two technologies to be deployed

• Sluicing with water

• High pressure water

Both technologies will be deployed on the Extended Reach Sluicer System (ERSS)

A Farm Retrieval Technologies

The following tanks are classified as sound: A-101, 102, 103 and 106

Two technologies to be deployed

• Sluicing with water

• High pressure water

Both technologies will be deployed on the ERSS

Tanks A-104 and A-105 are classified as assumed leakers

Regulatory Pathway for Hanford Tank Retrievals and Closure

Tank retrievals at C-Farm and of nine additional tanks are regulated under a Consent Decree milestone

Tank retrievals prior to 2010 were regulated under the Hanford Federal Facility Agreement and Consent Order, Appendix I (HFFACO)

Tanks that had retrieval regulated under the Consent Decree will be regulated under the HFFACO and DOE 435.1 (tank residuals) under the Closure process

Tanks Undergoing Retrieval will have the following:• Tank Waste Retrieval Work Plan outlining two retrieval technologies, and potentially a third

retrieval technology• Definition of tank retrieval completion• Request to forego a third retrieval technology if required• State approval to forego a third retrieval technology if necessary
