President's ColumnThe value of “fluffy” stuffANS NewsDecember 16, 2020, 9:23AM|Mary Lou Dunzik-GougarMary Lou Dunzik-GougarYou know the old saying that those who can, do, and those who can’t, teach? Well, I say anyone thinking that way should be kept far away from students!In my time at Argonne National Laboratory and Idaho National Laboratory, I worked with incredible scientists and engineers doing cutting-edge research. Unfortunately, making progress in research is not always conducive to the education and training of those who haven’t yet gained the necessary expertise. And there is an interesting phenomenon that occurs the more one gains in education and experience: We tend to forget what we were like before, what it was like not to know everything we do now. More than one of my PhD colleagues at the national labs dismissed the education and outreach efforts that I pursued in my spare time: scouts, K-12 classroom visits, teacher workshops, science expos, etc., viewing any focus other than the truly technical as just “fluffy” and a waste of valuable time and effort.In this issue of Nuclear News, the emphasis is on education. Students from all over the world come to the United States to attend our quality universities. But we all know that a student’s interest in science and engineering is ignited long before post-secondary education. We cannot underestimate the value of K-12 education. Most people leaving high school don’t go on to study engineering and science, but they do go on to raise families, pay taxes, and vote for government officials that impact energy policy. Why would we not want to raise the nuclear knowledge quotient of every single student?Working with Discovery Education and the Department of Energy, ANS over the past few years has developed a wealth of K-12 curriculum materials called Navigating Nuclear. These materials are available at no cost to educators and truly engage teachers and students. The hard development work has been done, and although there has been adoption, now we need to focus on getting Nuclear in Every Classroom.As a nuclear professional, you can play an important role in promoting Navigating Nuclear in your local area and serving as a resource. With so much remote education now, you can even expand your reach far beyond local. Educating the next generation is anything but fluff, so please check out the materials at Navigating Nuclear and spread the word!—Mary Lou Dunzik-Gougar, ANS PresidentTags:anldiscovery educationdoeeducationengineersinlk-12navigating nuclearscientiststeachingShare:LinkedInTwitterFacebook
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
ORISE reports uptick in nuclear engineering master’s degreesAn increase in the number of master’s degrees awarded in the United States in 2019 pushed the total number of nuclear engineering degrees to its highest level since 2016, according to a study conducted by the Oak Ridge Institute for Science and Education (ORISE) that surveyed 34 U.S. universities with nuclear engineering programs.

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
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
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
