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.

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

evaporated is equivalent

to over 10 years’ worth

of leakage at estimated

2014 leak rate

(~1.8 gal/day).

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

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

➢ ORP striving to have all remaining technical

issues resolved in 2018 and return WTP

➢ WTP Pretreatment production engineering to

proceed following technical issue resolution

and availability of project funding

➢ Complete facility designs and safety basis
