C-105 Retrieval
• Single-shell tank C-105 is the last
of 16 tanks to be retrieved in C
Farm. Approximately 30,000
gallons of waste remain in the tank.
• Installation of two extended-reach
sluicers is nearly complete. The
sluicers will be used to help
retrieve the remaining waste.
• The final round of retrieval is
expected to begin in August and be
completed in late 2017 or early
2018.
Crews check whether a riser will allow for the
installation of new equipment needed to
complete retrieval.

A-AX Single-Shell Tank Farms
• Cleaned out eight pits to support long-
length equipment removal from tanks
AX-102 and AX-104 – the first to be
retrieved.
• Cleanout included removal of old
jumpers, leak detectors and
miscellaneous components.
• Removed first piece of long-length
equipment (thermocouple from AX-102).
• Field testing AX exhausters and
ventilating AX Farm tanks.
• Continued fabrication of two exhausters
to be used to ventilate A Farm tanks
during equipment removal/installation
and retrieval activities.The thermocouple is placed in a grout
box and will be shipped to ERDF for
permanent disposal.

at start of
exhauster
operation
• T-111 exhauster
operated for 7,382 hours
between July 2015 and
December 2016.
• Estimated 7,150 gal of
water removed (~6,400
from sludge; ~750 from
pool)
• Volume of water
evaporated is equivalent
to over 10 years’ worth
of leakage at estimated
2014 leak rate
(~1.8 gal/day).
11
242-A Evaporator Campaign
• First of two planned Evaporator
campaigns this summer was
completed July 15.
• 16-day campaign created about
200,000 gallons of double-shell
tank space.
• Comprehensive industrial
hygiene control strategy was
implemented for the campaign
to monitor and evaluate data
and brief workers.
• The next campaign is set to
begin in mid- to late August and
is expected to create an
additional 280,000 gallons of
tank space.
12
Liquid Effluent Retention Facility
• Installation of a new fabric cover
on one of the three large Liquid
Effluent Retention Facility’s
(LERF) storage basins is nearly
complete.
• First replacement of LERF basin
cover since operations began at
facility in 1994.
• Replacement of second basin
cover planned for FY 2018.
• LERF stores wastewater
generated by 242-A Evaporator
campaigns.
• Each of the LERF basins is
permitted to hold ~7.8 million
gallons of material.

Double-Shell Tank AY-102
• ~98% of waste removed
(over 744,000 total gallons)
• ~19,000 gal remaining as
of February 2017 (limit of
technologies)
• Standard and extended
reach sluicing systems
used to retrieve waste
• Inspection with high-
definition video camera
conducted in June 2017
• Video inspections will help
inform decision to repair or
close tank per settlement

Washington

Chemical Vapors Management
• Work to extend the 242-A
Evaporator stack from 63 feet
to 111 feet above ground was
completed in mid-June prior to
the start of the Evaporator
campaign.
• Down-select of detection and
monitoring technologies is
underway.
• Air-purifying respirator filter
cartridge testing continues.

WTP Analytical Laboratory
• Facility will provide processing information on WTP feed to ensure efficient WTP operations
• Analyses will be performed to meet permitting, process control, authorization basis, and waste form
qualification requirements
• The Lab is designed for continuous operation to support peak throughput for the WTP
• Proposed Lab Operating Permit available for public comment through September 1
23
More Progress at WTP
Three autosamplers were received at the
High-Level Waste Facility. When the plant
is operational, the autosampling system
will ensure the glass produced by the Vit
Plant meets all regulatory standards and
requirements.
The Balance of Facilities switchgear building, also known
as Building 91, was energized in March.
24
Low-Activity Waste Pretreatment System
• Completed 60% Design Review.
• Completed Preliminary Safety
Design Report.
• Developing system testing
reports.
• Permit modification available for
public comment through Sept.
15, 2017; public meeting Aug. 21
at Richland Library.
• Requesting DOE HQ approval of
Critical Decision 3A to begin site
preparation and fabrication of
selected equipment.
• Anticipating full construction
start by mid-FY 2019.

Pretreatment Facility Technical Issues Resolution
➢ Multiple technical challenges associated with ventilation system, including high-efficiency particulate air (HEPA) filters
➢ Complete engineering/nuclear safety assessments to ensure ventilation meets requirements
➢ Seismic ground motion criteria for WTP changed around 2005
➢ Complete structural analysis of standard vessel and strategy for structural upgrades to installed vessels
➢ Perform failure modes, effects, and criticality analysis➢ Complete conceptual design of planning areas 2, 3, and 4
➢ Concern with adequacy of pulse jet mixer (PJM ) mixing and control system
➢ Complete testing of standard high solids vessel prototype
➢ Uncertainties exist in waste feed characteristics and ability to meet 40-year service life
➢ Confirm erosion/corrosion design basis, including margin, through testing and analysis
➢ Flammable gases generated by waste treated in WTP could accumulate in process piping and cause deflagration event
➢ Resolved by updating WTP safety basis, basis of design, and process piping design criteria to prevent or control potential
hydrogen explosions
➢ Dense fissile particles could settle on the bottom of Waste Treatment and Immobilization Plant (WTP) vessels with sufficient
mass and geometry such that a criticality event is credible
➢ Issue resolved via calculations, engineering and chemistry studies, criticality safety evaluations, and integrated process
controls
➢ Risk of combustion in the headspace of high-solids vessels due to hydrogen accumulation
➢ Resolved with approval of revised hydrogen safety control strategy consisting of both preventive and mitigative safety and
process controls
