The release of the 66-page report, A Time of Transition and Transformation: EM Vision 2020-2030, was announced on March 9 by William “Ike” White, DOE senior advisor for environmental management, during the 2020 Waste Management Conference in Phoenix, Ariz.What it says: Since 1989, EM has completed work at 91 of the original 107 DOE remediation sites, shrinking its overall program footprint by 90 percent. In this new report, EM projects further achievements this year and in the years ahead at the remaining locations in 11 states.“The strategic vision not only lays out EM’s planned slate of accomplishments for this year but also outlines a decade of anticipated progress across the breadth of the program,” White said.The report highlights planned achievements between 2020 and 2030, including the following:Initiating radioactive tank waste treatment at the Hanford Site in Washington State.Closing 22 of 51 underground waste tanks and completing the disposal of legacy transuranic waste at the Savannah River Site in South Carolina.Completing the construction of the Outfall 200 Mercury Treatment Facility, along with completing the disposition of the remaining legacy transuranic waste and uranium-233 at the Oak Ridge Reservation in Tennessee.Completing the treatment of remaining liquid sodium–bearing waste and completing shipments of legacy transuranic waste from the Idaho National Laboratory site.Completing key infrastructure upgrades at the Waste Isolation Pilot Plant in New Mexico.Completing legacy cleanup activities at the Nevada National Security Site.The EM strategic vision report can be found at <www.energy.gov/em/mission/annual-priorities-strategic-vision>.Tags:doeenvironmental managementstrategic visionShare:LinkedInTwitterFacebook
Fukiushima Daiichi: 10 years onThe Fukushima Daiichi site before the accident. All images are provided courtesy of TEPCO unless noted otherwise. It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.Go to Article
Search for new Hanford tank waste contractor beginsWorkers retrieve waste from a single-shell tank at the Hanford Site earlier this year. Photo: DOEThe Department of Energy’s Office of Environmental Management (EM) has issued a draft request for proposals for the new Integrated Tank Disposition Contract at the Hanford Site near Richland, Wash. The 10-year, $26.5 billion contract will replace the Tank Operations Contract currently held by Washington River Protection Solutions, and the scope will be expanded to include the operation of the Waste Treatment and Immobilization Plant (WTP) after radiological, or “hot,” commissioning of the plant is completed.The DOE had awarded a tank closure contract to a team led by BWX Technologies in May of last year, but later rescinded that decision after protests were raised by the two losing contract bidders.About 56 million gallons of radioactive waste is contained in Hanford’s 177 aging underground tanks. The WTP, which is still under construction, will vitrify the waste after it has been separated into low- and high-activity waste streams.Go to Article
Researchers report fastest purification of astatine-211 needed for targeted cancer therapyAstatine-211 recovery from bismuth metal using a chromatography system. Unlike bismuth, astatine-211 forms chemical bonds with ketones.In a recent study, Texas A&M University researchers have described a new process to purify astatine-211, a promising radioactive isotope for targeted cancer treatment. Unlike other elaborate purification methods, their technique can extract astatine-211 from bismuth in minutes rather than hours, which can greatly reduce the time between production and delivery to the patient.“Astatine-211 is currently under evaluation as a cancer therapeutic in clinical trials. But the problem is that the supply chain for this element is very limited because only a few places worldwide can make it,” said Jonathan Burns, research scientist in the Texas A&M Engineering Experiment Station’s Nuclear Engineering and Science Center. “Texas A&M University is one of a handful of places in the world that can make astatine-211, and we have delineated a rapid astatine-211 separation process that increases the usable quantity of this isotope for research and therapeutic purposes.”The researchers added that this separation method will bring Texas A&M one step closer to being able to provide astatine-211 for distribution through the Department of Energy’s Isotope Program’s National Isotope Development Center as part of the University Isotope Network.Details on the chemical reaction to purify astatine-211 are in the journal Separation and Purification Technology.Go to Article

DOE steps up plutonium production for future space explorationThis high-resolution still image is from a video taken by several cameras as NASA’s Perseverance rover touched down on Mars on February 18. Credits: NASA/JPL-CaltechNASA’s Perseverance rover, which successfully landed on Mars on February 18, is powered in part by the first plutonium produced at Department of Energy laboratories in more than 30 years. The radioactive decay of Pu-238 provides heat to radioisotope thermoelectric generators (RTGs) like the one onboard Perseverance and would also be used by the Dynamic Radioisotope Power System, currently under development, which is expected to provide three times the power of RTGs.Idaho National Laboratory is scaling up the production of Pu-238 to help meet NASA’s production goal of 1.5 kg per year by 2026, the DOE announced on February 17.Go to Article
NASA’s radioisotope-powered science will persevere on MarsMembers of the Perseverance rover team in Mission Control at NASA’s Jet Propulsion Laboratory react after receiving confirmation of a successful landing. Photo: NASA/Bill IngallsNASA mission control and space science fans around the world celebrated the safe landing of the Mars 2020 Perseverance rover on February 18 after a journey of 203 days and 293 million miles. Landing on Mars is difficult—only about 50 percent of all previous Mars landing attempts have succeeded—and a successful landing for Perseverance, the fifth rover that NASA has sent to Mars, was not assured. Confirmation of the successful touchdown was announced at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., at 3:55 p.m. EST.“This landing is one of those pivotal moments for NASA, the United States, and space exploration globally—when we know we are on the cusp of discovery and sharpening our pencils, so to speak, to rewrite the textbooks,” said acting NASA administrator Steve Jurczyk. “The Mars 2020 Perseverance mission embodies our nation’s spirit of persevering even in the most challenging of situations, inspiring, and advancing science and exploration. The mission itself personifies the human ideal of persevering toward the future and will help us prepare for human exploration of the Red Planet.”Only radioisotope thermoelectric generators (RTG) can provide the long-lasting, compact power source that Perseverance needs to carry out its long-term exploratory mission. Perseverance carries an RTG powered by the radioactive decay of plutonium-238 that was supplied by the Department of Energy. ANS president Mary Lou Dunzik-Gougar and CEO and executive director Craig Piercy congratulated NASA after the successful landing, acknowledging the critical contributions of the DOE’s Idaho National Laboratory, Oak Ridge National Laboratory, and Los Alamos National Laboratory.Go to Article

Savannah River crews remove cesium columns from tank closure unitWork crews remove the first column filled with cesium from the Tank Closure Cesium Removal unit by crane in H tank farm at the Savannah River Site. Photo: DOEColumns filled with cesium have been removed at the Savannah River Site in a demonstration project designed to accelerate removal of radioactive salt waste from underground tanks.“On the surface, it appeared to be like any other crane lift and equipment transport, which are routinely performed in the tank farms. However, this equipment contained cesium-rich, high-level waste, which was transported aboveground via roadway to an on-site interim safe storage pad,” said Savannah River Remediation (SRR) president and project manager Phil Breidenbach. “It was all handled safely and executed with outstanding teamwork by our highly skilled workforce.”Operated by liquid waste contractor SRR, a system known as the Tank Closure Cesium Removal (TCCR) unit removes cesium from the salt waste in Tank 10 in the site's H Tank Farm. The TCCR is a pilot demonstration that helps accelerate tank closure at the site, according to a report by the Department of Energy on February 9.Go to Article
