Hanford Collaborates With Universities on Robots to Evaluate Tank Integrity

November 17, 2022

RICHLAND, Wash. – Robot technology is providing new ways to monitor the integrity of underground double-shell waste-storage tanks at the Hanford Site.​

Under a cooperative agreement with DOE, Florida International University (FIU) recently worked with EM Office of River Protection (ORP) tank operations contractor Washington River Protection Solutions (WRPS) to test a miniature magnetic rover, deploying it at a tank in the site’s AP Tank Farm.

“It is always great to see the research that the students have been performing successfully deployed in the field,” said Genia McKinley, program manager for the DOE-FIU Cooperative Agreement. “It shows the capabilities of our students and the payoff for their hard work in real time.”

The rover underwent rigorous testing at FIU, followed by a final demonstration at a vendor facility in Richland, Washington. The demonstration showcased the abilities of the device and allowed field crews to familiarize themselves with the rover before deploying it over 50 feet deep into air cooling slots in the bottom of the tank.

Crews directed the rover as it shot video of both steel shells of Tank AP-105. The contractor’s tank integrity team will use the footage in their assessment of the structural integrity of the inner shell.

“We get excited about these kinds of projects,” said Glenn Soon, operations specialist with WRPS. “The university’s team worked with us to create this reliable, first-of-a-kind solution for tank inspections. Reaching the point of deploying the mini rover successfully has been very rewarding, and the rover shows a lot of promise for use in our tank integrity monitoring program.”

The mini rover was one of two technologies FIU recently tested at Hanford. The second is a robot called a pipe crawler. It was designed to travel through pipes underneath waste tanks, using air pressure rather than a motor. For the demonstration, the crawler was outfitted with a mock-up radiation scanner unit to simulate future measurements of gamma radiation and a camera to shoot footage for visual inspections​

“We had initially designed this crawler to clean transfer lines, and when we learned that WRPS was looking for a way to survey underground pipes, we retrofitted the design for single-shell tank lateral gamma detection,” said Anthony Abrahao, FIU research scientist. “Students were highly involved in designing and building the crawler. They created pieces of the crawler with a 3D printer and collaborated with students at a university near Hanford to develop a system to deploy the crawler.”

A group of five interns at Washington State University’s (WSU) Tri-Cities campus in Richland designed a cable management system to retrieve the crawler once it completes scanning inside the pipes. The FIU team gave the WSU team design specifications to allow the two systems to work together, and the WSU team came up with a reel that could automatically deploy the crawler at regular intervals without human involvement.

“This was such a unique learning opportunity,” said Misty Lace, a WSU mechanical engineering student. “All seniors have to work on a project, but we were one of the only groups that got to build something with a real-world application, coordinate our design with students on the other side of the country and then come together to test it.”

FIU DOE Fellow Jeff Natividad had roles in creating and testing both robots during back-to-back internships with WRPS at Hanford.

“I love robotics, but I hadn’t considered that it could apply to an environmental remediation task like this,” Natividad said. “I would like to see more students get involved in this kind of project so they can better understand the nuclear industry and the cool career opportunities that are available.”

Idaho Site Begins Path to End State for Cold War Landfill

October 25, 2022

Idaho Site.jpg

The Subsurface Disposal Area, foreground, at the Idaho National Laboratory (INL) Site will undergo a significant transformation over the next two years. EM and its INL Site contractor are set to demolish the soft-sided Accelerated Retrieval Project buildings to prepare the Cold War-era landfill for its end state.

IDAHO FALLS, Idaho – EM’s Idaho Cleanup Project (ICP) recently took the first step toward achieving an end state for a Cold War-era landfill where crews have completed cleanup.

ICP and contractor Idaho Environmental Coalition (IEC) signed a contract agreement outlining the scope, cost and schedule for demolishing above-ground, soft-sided structures at the 97-acre Subsurface Disposal Area (SDA) at EM’s Idaho National Laboratory Site.

That first step is an important one, according to Connie Simiele, senior director of IEC Essential Missions.

“This first end-state task order is the result of excellent teamwork and is a critical step in the delivery of our contract,” she said.

The initial work covered by the contract agreement was demolition of Accelerated Retrieval Project (ARP) IV, where workers removed targeted buried waste in 2010. IEC tore down ARP IV on Oct. 14.

Next, crews will demolish ARP V, which was used to exhume targeted radioactive and hazardous waste from Pit 9, a one-acre disposal pit that accepted primarily Rocky Flats Plant waste from 1967 to 1969. Demolition of other ARP structures will follow the teardown of ARP IV and V.

From 2005 to early 2022, crews removed targeted radioactive and hazardous waste from a combined 5.69 acres of the SDA. Waste removal took place in nine soft-sided ARP buildings. EM completed demolition of two of those buildings — ARPs I and VI — in 2012 after waste exhumation was complete.

Once all ARP buildings are demolished, the debris will be left in place and covered with clean gravel. It will serve as the base of an earthen cover that will be constructed over the entire SDA to protect the underling Snake River Plain Aquifer.

In addition to demolishing buildings, the contract agreement includes the scope, schedule and cost of formally closing wells once used to extract and treat solvent vapors beneath the landfill. The vapors were present in degreasers used during weapons development work.

The degreasers and other solvents were placed in barrels and boxes that were buried in shallow, unlined trenches in the SDA. Over time, the barrels and boxes degraded, releasing the vapors into the surrounding soil.

Dan Coyne, senior director of IEC Waste Management and Decontamination and Demolition, said he was pleased with the final contract agreement.

“This complex proposal was only possible with the hard work, timely input and structured approach of a knowledgeable, integrated project team,” Coyne said.

The work detailed in the agreement is to be completed by the end of 2024.

Savannah River Site Delivers EM 2022 Priority With Disposal Unit Progress

October 11, 2022

picture1_original.jpeg
Savannah River Site liquid waste contractor Savannah River Mission Completion has achieved an EM 2022 priority by completing all concrete placements on Saltstone Disposal Unit 9.


 AIKEN, S.C. − The liquid waste contractor at Savannah River Site (SRS) met an EM 2022 priority with the recent completion of concrete placements on Saltstone Disposal Unit (SDU) 9.

The construction team for Savannah River Mission Completion (SRMC) performed the work ahead of schedule and under budget.

SRMC SDU Project Manager Tim Hammond praised the effort of the liquid waste construction team for safely meeting the priority within the specified timeframe.

“Completing our concrete placements on SDU 9 is another major accomplishment for the overall SDU Program,” Hammond said. “These units continue to be a success story, and I am proud to be part of a great team. Achieving this priority while moving forward with other construction projects demonstrates our team’s dedication to doing our job — and doing it safely and doing it well.”

SDUs are massive, 34-million-gallon units that hold a grout that’s a mixture of decontaminated salt solution (DSS) combined with dry materials called slag and fly ash. This grout hardens like cement. SDUs are the final disposal location for the decontaminated waste stream and are integral to closing the remaining liquid waste tanks at SRS.

DOE-Savannah River Assistant Manager for Waste Disposition Jim Folk said construction of SDUs is crucial to the liquid waste mission.

“With the Salt Waste Processing Facility (SWPF) processing rates continuing to increase, these larger SDUs will be needed to keep up with the increased output,” Folk said.

SWPF has processed more than 900,000 gallons of waste since July.

An SDU closely resembles a large, cylindrical water tank that sits on the ground. Construction includes the placement of 25 wall sections, 208 support columns and seven roof sections — all made of concrete. Altogether, more than 20,000 cubic yards of concrete is needed to build each SDU, using approximately 700,000 total labor hours.

Before the SDU is ready to receive DSS, several additional tasks must be performed. Among the major work yet to be performed in SDU 9 is wrapping the SDU in high-strength cable, spraying it with concrete and installing top-of-tank pipes and electrical wiring.

Afterward, the tank will be tested for leaks and final construction punch-list items before being given clearance to operate.

Remaining tasks are expected to be completed within the next year, ahead of schedule. The first large-volume SDU built at SRS — SDU 6 — began receiving grout in 2018 and the second began receiving grout in October last year.

SDU 9 will be the fourth mega-volume unit to be built at SRS, with construction of units 10, 11 and 12 just getting underway. SRS has five smaller SDUs that hold about 3 million gallons each.

SRMC is also constructing SDU 8, entering the final stages before the new unit is tested for leaks.

To be most efficient, SDUs are being built “in series.” As a construction team finishes its specific task on one SDU, the group moves to another SDU and performs the same work. In-series construction saves on demobilization costs and capitalizes on ordering materials and equipment in bulk.

Hanford Evaporator Prepares for Tank Waste Treatment

January 09, 2022

phase-1-encasement-clamshell-welding-700-pixels_original.jpg
 
A worker installing new waste transfer lines between large, underground tanks and Hanford’s evaporator facility welds a secondary encasement on one of the lines. The project is on track for completion by the end of 2022 and will support the treatment of tank waste for disposal as part of the Direct-Feed Low-Activity Waste Program.

RICHLAND, Wash. – As the Hanford Site prepares for the start of operations to treat tank waste for disposal, workers are upgrading a number of facilities to ensure they are ready to support around-the-clock operations.

At the 242-A Evaporator, workers are upgrading equipment used to remove water from tank waste and systems that transfer waste to and from large, underground tanks near the facility. The upgrades will also extend the evaporator facility’s service life.

“Using the evaporator to create waste storage space in the double-shell tanks allows us to continue to retrieve waste from single-shell tanks and strategically stage waste for the next era of cleanup at Hanford, treating tank waste via the Direct-Feed Low-Activity Waste Program,” said Delmar Noyes, EM Office of River Protection (ORP) assistant manager for Tank Farms.

Located in Hanford’s 200 East Area near underground storage tanks and the Waste Treatment and Immobilization Plant, the evaporator boils waste at low pressure in steam heat to evaporate water from the waste. The resulting waste slurry is transferred back to a nearby double-shell tank farm, known as AW, for continued safe storage. The evaporated water is filtered and transferred to Hanford’s nearby Effluent Treatment Facility for additional treatment and disposal.

ORP tank operations contractor Washington River Protection Solutions (WRPS) has installed new waste transfer piping connections, called nozzles, in the AW Farm and the evaporator facility. To minimize worker exposure to radiation while installing nozzles at the evaporator, workers drilled through 22-inch-thick reinforced concrete walls that provide shielding from outside the building. Now, workers are making progress on the next phase of the project, installing new, double-walled waste transfer lines.

“Work is now focused on excavating trenches that are up to seven feet deep in some areas between the AW Farm and the evaporator, and welding together sections of transfer lines. In all, workers will install more than 1,200 feet of transfer lines,” said Dustin May, project manager for WRPS.

The project is scheduled for completion by the end of 2022, well ahead of the projected start date of tank waste treatment operations.

Savannah River Site Adds Innovation to Key Liquid Waste Facility System

January 09, 2022

shoc-recovery-pump-700-pixels_original.jpg
 

Savannah River Remediation (SRR) made significant improvements to the Saltstone Hopper Overflow Container at the Savannah River Site’s Saltstone Production Facility. Pictured is the container’s recovery pump, foreground, with piping and additional new equipment as part of the facility improvements.

AIKEN, S.C.  EM has developed a new, innovative system that reduces both operational downtime and personnel exposure at a key facility in the Savannah River Site (SRS) liquid waste system.

The Saltstone Production Facility (SPF), operated by EM’s liquid waste contractor Savannah River Remediation (SRR), receives decontaminated salt solution sent from the Salt Waste Processing Facility. SPF processes that solution into saltstone grout by mixing the liquid feed with dry materials. The grout is then pumped from SPF to saltstone disposal units, where the saltstone grout solidifies into a monolithic, non-hazardous, and solid low-level form, safe for permanent disposal.

At SPF, an overflow system called the Saltstone Hopper Overflow Container (SHOC) works as a safety feature that collects grout or flush water during instances such as grout pump hose ruptures, hopper overflow, or grout line overpressurization. Previously, any material that exceeded the SHOC capacity flowed into a process room trench that transferred the material to a nearby collection tank. Grout accumulated in the trench would harden and had to be chipped out by hand.

SRR developed and implemented a solution that solved this problem. The team installed a new system to reroute overflow from the SHOC and return the material to the grout line to prevent the material from entering the trench. Changes to the SHOC system included new equipment, such as piping and a recovery pump.

These modifications decrease facility downtime by months, reduce personnel exposure during recovery efforts and increase automation in plant response.

Jim Folk, DOE-Savannah River assistant manager for waste disposition, said strengthening SPF with the SHOC modifications will allow EM to continue its critical liquid waste mission.

“The Saltstone Production Facility is an important piece in the overall liquid waste system,” Folk said. “It is vital that the plant is running at its optimum capacity, especially now that it is receiving waste output from the Salt Waste Processing Facility.”

The innovations to the SHOC design, coupled with intensive maintenance over the last four years, are prime examples of SRR’s core values of continuous improvement and teamwork in action, according to Mark Schmitz, SRR chief operating officer and deputy project manager.

“The improvements made to the Saltstone Hopper Overflow Container demonstrate an impressive blend of expert design and skillful labor,” Schmitz said. “The improved system not only mitigates risk to the facility, but it also removes a significant burden on our maintenance and operations crews.”

International Collaboration Enhances Wastewater Treatment at Oak Ridge

January 09, 2022

flags-image-500-pixels_original.jpg
 
OAK RIDGE, Tenn. – A collaboration between EM and the United Kingdom is helping operations continue at a key wastewater treatment facility at Oak Ridge National Laboratory (ORNL), ensuring important research and environmental cleanup missions are not disrupted.

Oak Ridge Office of Environmental Management (OREM) cleanup contractor UCOR partnered with the National Nuclear Laboratory (NNL) in the U.K. to study new technologies and methods to remove cesium and strontium from wastewater at the Process Waste Treatment Complex (PWTC) at ORNL.

Working with their U.K. peers, UCOR employees benchmarked PWTC operations against those at the Site Ion-Exchange Plant at the Sellafield facility, a nuclear reprocessing plant that has operated in the U.K. for more than 40 years. The technical information and lessons exchanged have been significant for both parties.

“This is just the latest great example of how important engagement is with our international partners to move the cleanup mission forward,” said Joceline Nahigian, director of EM’s Office of Intergovernmental and Stakeholder Programs. “This most recent collaboration is well timed as we move toward renewing the agreement allowing for continued engagement with the U.K. team to enable cleanup activities.”

After UCOR implemented the recommendations from the collaboration, the PWTC has operated consistently for periods of more than 90 days compared with just a few days at a time before the changes were made.

“Thanks to the input from the U.K. team, we have been able to triple our operating time while achieving more consistent, effluent numbers,” UCOR System Engineer Jason Jeansonne said. “This improvement in performance has eliminated previous day-to-day operating concerns and allowed us to focus attention on permanent improvements in the ion-exchange approach.”

In addition to the operational benefits at Oak Ridge, Sellafield Ltd. and NNL also gained useful insight into the challenges being faced and the information gleaned will be useful in helping to identify ion-exchange resins that could potentially be used to support Sellafield Ltd. cleanup operations in the future. Discussions in this area are ongoing as testing and operations at Oak Ridge continue to progress. Sellafield Ltd. is the company tasked with cleaning up the Sellafield site.

Approximately 90 million gallons of wastewater are generated by research and cleanup operations at ORNL annually. That water is collected and treated in the PWTC system.

Known as Liquid and Gaseous Waste Operations, the overarching infrastructure consists of numerous interconnected facilities that support crucial waste treatment activities for EM and the DOE Office of Science. UCOR recently supported EM’s plan to reduce the cost of treating wastewater by consolidating capabilities into a single facility.

Due to its age and deteriorated condition, Building 3544, the PWTC facility that treated radiological waste, presented one of the largest risks. The building had served as a radiological wastewater treatment facility for more than four decades. It housed an older zeolite treatment system designed to remove cesium and strontium from wastewater. Zeolite is a naturally-occurring mineral formed from volcanic ash which can strip contaminants from wastewater.

OREM installed a new zeolite treatment system in Building 3608 that consolidates treatment of both radiological and non-radiological waste into one facility rather than two. The consolidation allowed EM and UCOR to shut down Building 3544 and prepare it for decommissioning and demolition.

Savannah River Site Enhances Pumps to Improve Tank Waste Retrieval

October 12, 2021

srs pumps.jpg
An enhanced commercial submersible mixer pump, designed by Savannah River Remediation for use in Tank 33 bulk waste removal efforts, arrives at the Savannah River Site​
 

AIKEN, S.C.  EM and it’s liquid waste contractor at the Savannah River Site (SRS) have developed a unique commercial mixer pump to use in a tank with space limitations, allowing waste retrieval efforts to advance in the tank farms.

Savannah River Remediation (SRR) currently uses commercial submersible mixer pumps (CSMPs) as the primary mixing device for waste retrieval in the majority of the tanks. The tank waste, composed of salt and sludge, needs to be mixed with water to allow the waste to be moved between tanks via transfer pumps and lines.

Typically, four CSMPs are used in each tank based on each pump’s nozzle discharge reach, known as the effective cleaning radius. The pumps are inserted into the tank through riser openings at the top of waste tanks. However, in Tank 33, cooling coils are deployed in the openings, limiting the space for the pumps to be inserted. Other tanks have internally built cooling coils that do not limit the number of access riser openings in a tank.

For this reason, SRR designed an enhanced version of the mixer pumps specifically for Tank 33. It will provide a 50-foot effective cleaning radius within the tank versus the 29-foot radius provided by the regular CSMPs. The longer effective cleaning radius decreases the number of pumps from four to three that are needed during the bulk waste removal process.

The enhanced CSMP is the first-of-its-kind pump developed for SRR, according to Mark Schmitz, SRR chief operating officer and deputy project manager.

“The successful implementation of the enhanced mixer pump is essential for the current strategy of bulk waste removal in Tank 33,” Schmitz said. “Once proven successful in Tank 33, SRR could deploy enhanced pumps in similar tanks.”

Tank 33 is one of six waste tanks currently undergoing waste removal efforts, which advances EM’s mission of waste tank closure, according to DOE-Savannah River Assistant Manager for Waste Disposition Jim Folk.

“Removing waste from aging waste tanks continues to be one of the Department’s top priorities because each tank emptied reduces the risk posed to the community and environment,” Folk said. “The development of innovative solutions to continue waste retrieval efforts when faced with infrastructure or operational challenges is key to our long-term success.”

The enhanced CSMP was developed by a small business named GPM, Inc.

WASHINGTON, D.C. – Members of EM leadership recently visited Catholic University’s Vitreous State Laboratory (VSL), a contributor to key innovations in the vitrification technology central to Hanford’s Waste Treatment and Immobilization Plant (WTP) in Washington state.

EM Acting Assistant Secretary William “Ike” White, EM Associate Principal Deputy Assistant Secretary for Field Operations Nicole Nelson-Jean, and EM Chief Engineer Robert Crosby toured the VSL facility and received updates about its various labs and projects that support the safe immobilization of nuclear waste at DOE sites, including the Savannah River Site (SRS) in South Carolina.

Over the years, the VSL and Atkins Nuclear Secured team have helped EM continually improve efficiency in melter design and operation. VSL and Atkins have also introduced technology solutions that will avoid billions in lifecycle costs at Hanford, SRS, and the Rokkasho Nuclear Fuel Reprocessing Facility in Japan.

VSL has consistently provided technology solutions to Hanford’s WTP program since 1994 through a successful university-industry partnership with Atkins. The partners were the primary contributors to the WTP vitrification development program and initiated the WTP low-activity and high-level radioactive waste loading and melt rate enhancement program with EM’s Office of River Protection in 2003. Vitrification involves turning high-level radioactive waste into a glass form by blending it with glass-forming materials and heating it to 2,100 degrees Fahrenheit.

Atkins Nuclear Secured Chief Operating Officer Jack Craig and Atkins Engineering and Technology Senior Vice President Brad Bowan hosted White, Nelson-Jean, and Crosby. During the visit, VSL Director and Physics Professor Ian Pegg discussed the usage of vitrification, provided a glass pouring demonstration, and gave a tour of the DuraMelter facilities, home to the largest test melter in the U.S. The group also made stops at the glass leaching, analytical, and nanotechnology laboratories.

VSL and Atkins also assist DOE and the nuclear industry in the fields of robotics and emerging digital technologies. White, Nelson-Jean, and Crosby viewed a demonstration of the Spot quadruped robot, which is being developed to help insulate workers from environmental hazards during routine inspections and surveys.

VSL is widely recognized as a center of excellence in glass science and technology. The laboratory’s experts have developed processes to more efficiently transform highly radioactive nuclear waste into stable glass that can be disposed safely. The center provides support to various nuclear facilities in the U.S., Japan, and United Kingdom.​
