In this week’s “EM Update,” the Department of Energy’s Office of Environmental Management (EM) reports that its contractor Savannah River Nuclear Solutions (SRNS) has successfully reduced degreasing solvents in the aquifer beneath the Savannah River Site in South Carolina using a technology that injects a form of iron and oil into groundwater.
“The oil attracts the Cold War[–era] cleaning solvents while the iron degrades and neutralizes the contamination,” said Shannan Lucero, SRNS manager for area closure projects.

A contractor for the Department of Energy’s Office of Environmental Management (EM) started tearing down a 1940s-era facility in May at the Y-12 National Security Complex in Oak Ridge, Tenn. Demolition of the former Criticality Experiment Laboratory, also known as Building 9213, is the latest project by EM to address a large inventory of high-risk excess contaminated facilities at the Oak Ridge Reservation.

Officials from the Department of Energy’s Office of Environmental Management recently got a firsthand look at cleanup progress being made at the Paducah Site in western Kentucky. The site is owned by the DOE, which is overseeing environmental cleanup activities there, including environmental remediation, waste management, depleted uranium conversion, and decontamination and decommissioning.
The visit by Dae Chung, associate principal deputy assistant secretary for corporate services, and other EM officials included stops at the C-400 cleaning building remediation project, the new Large Item Neutron Assay System (LINAS), and the C-333 process building deactivation.
Savannah River National Laboratory recently oversaw a demonstration of a new radiological inspection technology called iGART, a ground-based robot that conducts radiological and nuclear inspections. The DOE’s Office of Environmental Management used the demonstration at the Savannah River Site to determine if there is an application value for iGART at SRS or other EM sites. (Photos: DOE)
The Department of Energy’s Office of Environmental Management is looking to continue developing technology to aid in site cleanup activities if its fiscal year 2023 budget request is approved. The $7.64 billion budget request includes about $25 million for EM’s Technology Development Office.

Without a plan for addressing issues in completing construction projects at the Waste Isolation Pilot Plant in New Mexico, the Department of Energy cannot ensure that further cost increases and schedule delays will not continue, according to a report by the Government Accountability Office. In particular, the GAO said, the DOE has not developed a corrective action plan to address root causes identified for the rising cost and the delay in building a new ventilation system at the transuranic waste repository.

The last spent nuclear fuel elements from Idaho National Laboratory’s Advanced Test Reactor (ATR) have been retrieved from a water-filled storage basin and transferred to a nearby dry-storage facility in accordance with a 1995 agreement with the State of Idaho, the Department of Energy’s Office of Environmental Management (EM) announced this week.

Isotek, the Department of Energy contractor responsible for overseeing the inventory of uranium-233 at Oak Ridge National Laboratory and preparing it for removal from the site, said it plans to resume preparations for processing high-dose U-233 in March. The company was forced to suspend its operational readiness review of the Initial Processing Campaign at Oak Ridge in January due to issues related to COVID-19, as well as difficulties operating in colder temperatures.

The Department of Energy’s Office of Environmental Management (EM) stated on February 22 that its Idaho National Laboratory Site contractor is operating the final test run of the Integrated Waste Treatment Unit (IWTU), running waste simulant through the facility to ensure the plant’s performance and personnel proficiency for upcoming radiological operations.

The Department of Energy’s Office of Environmental Management (EM) announced on February 10 that it is set to deactivate and demolish the prototype for the reactor used for the USS Nautilus, the world’s first operational nuclear-powered submarine and the first submarine to complete a submerged transit of the North Pole.

The Department of Energy announced on Wednesday that the first large-scale treatment of radioactive and chemical waste from underground tanks at the Hanford Site near Richland, Wash., has begun with the start of operations of the Tank-Side Cesium Removal (TSCR) System.
The newly operational TSCR System removes radioactive cesium and solids from the tank waste. The treated waste will be fed directly to the nearby Waste Treatment and Immobilization Plant (WTP) for vitrification when the plant comes on line next year.

The Department of Energy’s Office of Environmental Management (EM) announced this week that preparations are well underway for the transfer of nearly 2,000 highly radioactive cesium and strontium capsules from the Waste Encapsulation and Storage Facility (WESF) to interim dry storage at the Hanford Site near Richland, Wash.

Having completed all startup testing of components and systems, the Waste Treatment and Immobilization Plant (WTP) at the Hanford Site near Richland, Wash., has moved to the commissioning phase, the Department of Energy’s Office of Environmental Management (EM) announced last week. During the commissioning phase, the final steps will be taken to prepare for the vitrification of radioactive and chemical waste as part of Hanford’s Direct-Feed Low-Activity Waste (DFLAW) program.
DOE liquid waste contractor Savannah River Remediation is moving forward with Saltstone Disposal Unit projects to support the Salt Waste Processing Facility at the Savannah River Site.
The Department of Energy’s Office of Environmental Management (EM) has authorized the use of a second mega-volume saltstone disposal unit (SDU) at the Savannah River Site in South Carolina. Savannah River Remediation (SRR), EM’s liquid waste contractor at SRS, received Critical Decision-4 for Saltstone Disposal Unit 7, marking the final step in the approval process before beginning operations.

The Department of Energy’s Office of Environmental Management (EM) has awarded Savannah River Mission Completion (SRMC), of Lynchburg, Va., the Integrated Mission Completion Contract at the Savannah River Site near Aiken, S.C. The single-award, master indefinite delivery/indefinite quantity contract has an estimated contract ceiling of approximately $21 billion over a 10-year ordering period, with cost-reimbursement and fixed-price task orders to define the contract performance.
