Using a specialized radiation detector, Department of Energy cleanup contractor UCOR is characterizing a hot cell at Oak Ridge National Laboratory in preparation for its demolition. The detector overlays a radiation-intensity color-map on a picture of the environment and identifies gamma-emitting nuclides and their locations.

The Department of Energy’s Office of Environmental Management this week announced that after seven years, mining of the Waste Isolation Pilot Plant’s Panel 8 is finished. Created from an ancient salt formation 2,150 feet below the surface, Panel 8’s seven emplacement rooms are the next destination for transuranic waste brought to WIPP from DOE sites throughout the country.

A team of scientists from the United Kingdom’s University of Bristol were given access to the Chernobyl nuclear power plant in Ukraine, advancing a project to train robots and artificial intelligence systems to measure radiation and create 3D maps.
A slideshow of the team’s visit to Chernobyl’s Unit 4 control room and New Safe Confinement structure, where they deployed radiation mapping and scanning sensors, including a LIDAR-equipped robot call Rooster, appears on Gizmodo.

Washington state and Oregon will receive approximately $33.5 million through four financial assistance grants from the Department of Energy to fund programs related to the cleanup of the department’s Hanford Site near Richland, Wash. The grants will support environmental response regulatory activities, emergency preparedness, and public information programs in the two states.
All four grants, which were noncompetitively awarded, are for fiscal years 2022 through 2026.
Savannah River Remediation workers double-stack HLW canisters in an underground vault in Savannah River’s Glass Waste Storage Building 2 using a one-of-a-kind shielded canister transporter. (Photo: DOE)
The Department of Energy’s Office of Environmental Management (EM) has demonstrated the capability to expand the double-stacking of high-level waste canisters at the Savannah River Site in South Carolina. That approach will save the site’s cleanup program millions of dollars, according to the DOE.

The demolition of the final of 18 DOE-owned buildings at the Energy Technology Engineering Center (ETEC) has been completed, according to the DOE. The ETEC is the former liquid metals research facility located at the Santa Susana Field Laboratory (SSFL), northwest of Los Angeles.
Spent nuclear fuel in dry storage at the decommissioned Zion nuclear power plant in Illinois.
Congress needs to take action to break the impasse over a permanent solution for commercial spent nuclear fuel, according to a report by the U.S. Government Accountability Office. The GAO recommends that Congress amend the Nuclear Waste Policy Act (NWPA) to authorize a new consent-based siting process, restructure the Nuclear Waste Fund, and direct the Department of Energy to develop and implement an integrated waste management strategy.
The GAO also recommends that the DOE finalize the consent-based process it began in 2015 for siting consolidated interim storage and permanent geologic repository facilities. The DOE agrees with that recommendation.

Scientists at Lawrence Livermore National Laboratory, working in collaboration with researchers at Penn State University and Harvard Medical School, have discovered a new mechanism by which radionuclides could spread in the environment.
The research, which has implications for nuclear waste management and environmental chemistry, was published in the Journal of the American Chemical Society on September 20.

The German government has announced that it is closing the Gorleben salt mine in the Wendland region of Lower Saxony, officially removing the site from consideration as a repository for radioactive waste. Gorleben became a target of antinuclear protests after being proposed as a potential repository in the 1970s.

Orano has delivered its first TN-LC spent nuclear fuel transport cask to Korea Hydro and Nuclear Power Company. The first use of the cask is planned for an international transport between South Korea and Sweden by the end of 2021.
KHNP received a license in June for the TN-LC transport cask from the Nuclear Safety and Security Commission, South Korea’s regulatory agency, for the transport of high-burnup spent fuel.

The Department of Energy is celebrating a major milestone in its tank waste mission at the Hanford Site near Richland, Wash. DOE tank operations contractor Washington River Protection Solutions has finished construction of the pipeline that will carry treated waste from an underground tank to the Waste Treatment and Immobilization Plant (WTP) for vitrification.

Nuclear waste should not be used as an excuse for trying to shut down nuclear reactors, says radiation safety expert Andrew Karam in his recent article for the American Council on Science and Health titled, “Let’s Talk about Radioactive Waste."
The DOE recently completed startup testing on the uninterruptable electrical power system for Hanford’s Low-Activity Waste Facility.
Department of Energy workers recently finished startup testing of a battery-powered backup electrical system for the Low-Activity Waste (LAW) Facility at the Hanford Site near Richland, Wash. According to the DOE’s Office of Environmental Management (EM), the uninterruptable electrical power system is vital to safeguarding the facility, part of Hanford’s Waste Treatment and Immobilization Plant, in the unlikely event of a temporary power loss to the plant.

The Defense Nuclear Facility Safety Board, which provides independent federal oversight of Department of Energy weapons facilities, has reported that low-level radioactive and other combustible waste is accumulating in the basement of Los Alamos National Laboratory’s Plutonium Facility (PF-4), and that housekeeping and waste management in the PF-4 basement have been a continuing challenge.
