Photo: DOEThe Tokamak Fusion Test Reactor (TFTR) at Princeton University and the Fuel Cycle Facility (FCF) (now known as the Fuel Conditioning Facility) at Idaho National Laboratory have been designated as ANS Nuclear Historic Landmarks. The official awarding of the honors will occur during the 2020 ANS Virtual Winter Meeting, which begins November 16.The TFTR received the award for demonstrating significant fusion energy production and tritium technologies for future nuclear fusion power plants and for the first detailed exploration of magnetically confined deuterium-tritium (D-T) fusion plasmas.INL’s FCF and its Experimental Breeder Reactor II (EBR-II) were honored for demonstrating on-site recycling of used nuclear fuel back into a nuclear reactor.TFTR background: The TFTR Project was initiated in 1976. The facility went into operation in December 1982 and spent the next decade using weakly reacting deuterium fusion fuel to develop, understand, and achieve the plasma conditions, full performance of the tokamak, plasma heating systems, and plasma diagnostic systems required for the D-T mission. In 1993, it began the first magnetically confined fusion experiments using a 50:50 mix of deuterium and tritium, the fuel envisioned for future fusion power plants.Among the various scientific achievements generated through more than 1,000 D-T experiments was the first detailed study of the behavior of the alpha particles produced in the D-T fusion reaction that are critical in sustaining the fusion reaction in a fusion power plant.FCF EBR-II background: In the 1960s, FCF was constructed as part of the EBR-II Project at the Argonne National Laboratory–West site (now a part of INL). FCF demonstrated that spent, highly enriched uranium fuel could be remotely processed to recover the uranium, with the uranium recycled and remotely fabricated into new fuel to be returned to the reactor. The recycle process demonstrated in FCF was a low-decontamination, on-site, melt-refining process, based on work with uranium and plutonium separations initially performed in the Manhattan Project.What it means: The Nuclear Historic Landmark Award identifies and memorializes sites or facilities where outstanding physical accomplishments took place that were instrumental in the advancement and implementation of nuclear technology and the peaceful uses of nuclear energy. The award recognizes facilities that were placed in service 20 or more years ago. The designation of these sites is symbolized by an engraved bronze plaque for display at or near the original site. Each plaque is presented by an official representative of ANS at an appropriate ceremony.Tags:experimental breeder reactorfcffuel cycle facilityfusioninlnuclear historic landmark awardtftrtokamakShare:LinkedInTwitterFacebook
Understanding the ITER Project in the context of global Progress on Fusion(photo: ITER Project gangway assembly)The promise of hydrogen fusion as a safe, environmentally friendly, and virtually unlimited source of energy has motivated scientists and engineers for decades. For the general public, the pace of fusion research and development may at times appear to be slow. But for those on the inside, who understand both the technological challenges involved and the transformative impact that fusion can bring to human society in terms of the security of the long-term world energy supply, the extended investment is well worth it.Failure is not an option.Go to Article

INL’s MARVEL could demonstrate remote operation on a micro scaleThe Department of Energy launched a 14-day public review and comment period on January 11 on a draft environmental assessment for a proposal to construct the Microreactor Applications Research Validation & EvaLuation (MARVEL) project microreactor inside Idaho National Laboratory’s Transient Reactor Test (TREAT) Facility.The basics: The MARVEL design is a sodium-potassium–cooled thermal microreactor fueled by uranium zirconium hydride fuel pins using high-assay, low-enriched uranium (HALEU). It would be a 100-kWt reactor capable of generating about 20 kWe using Stirling engines over a core life of about two years.The DOE proposes to install the MARVEL microreactor in a concrete storage pit in the north high bay of the TREAT reactor building. Modifications to the building to accommodate MARVEL are anticipated to take five to seven months. Constructing, assembling, and performing preoperational testing are expected to take another two to three months prior to fuel loading.Go to Article
Fusion and the bounty of electricityFrom the time we discovered how the sun produces energy, we have been captivated by the prospect of powering our society using the same principles of nuclear fusion. Fusion energy promises the bounty of electricity we need to live our lives without the pollution inherent in fossil fuels, such as oil, gas, and coal. In addition, fusion energy is free from the stigma that has long plagued nuclear power about the storage and handling of long-lived radioactive waste products, a stigma from which fission power is only just starting to recover in green energy circles.

Reclassification of HLW could reduce risks while saving billions, DOE saysAn engineered stainless steel container designed to hold LLW at Hanford. Photo: Bechtel National, Inc.A Department of Energy report to the U.S. Congress shows that the reclassification of high-level radioactive waste could save more than $200 billion in treatment and disposal costs while allowing DOE sites to be cleaned up sooner—all still without jeopardizing public health and safety.The report, Evaluation of Potential Opportunities to Classify Certain Defense Nuclear Waste from Reprocessing as Other than High-Level Radioactive Waste, identifies potential opportunities for the DOE to reduce risk to public and environment while completing its cleanup mission more efficiently and effectively. Those opportunities are based on the DOE’s 2019 interpretation of the statutory term HLW, which classifies waste based on its radiological characteristics rather than its origin.Under the DOE’s interpretation of HLW, waste from the reprocessing of spent nuclear fuel may be determined to be non-HLW if the waste (1) does not exceed concentration limits for Class C low-level radioactive waste as set out in federal regulations and meets the performance objectives of a disposal facility; or (2) does not require disposal in a deep geologic repository and meets the performance objectives of a disposal facility as demonstrated through a performance assessment conducted in accordance with applicable requirements.Go to Article

The value of “fluffy” stuffMary 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.Go to Article
