Finland’s Onkalo repository a “game changer,” says IAEA’s Grossi

Iran has started work on uranium metal-based fuel for a research reactor, the United Nations’ nuclear watchdog and Tehran said on Wednesday. Kazem Gharib Abadi, Iran’s representative at the International Atomic Energy Agency, confirmed that the country has started working on the fuel, saying that everything has been reported to the agency.

Iran's action is the latest breach of its nuclear deal with six significant powers as it presses for a lifting of U.S. sanctions.

• ARDP picks divergent technologies in Natrium, Xe-100: Is nuclear’s future taking shape? The Department of Energy has put two reactor designs—TerraPower’s Natrium and X-energy’s Xe-100—on a fast track to commercialization, each with an initial $80 million in 50-50 cost-shared funds awarded through the Advanced Reactor Demonstration Program.

Adequate uranium resources exist to support the long-term, sustainable use of nuclear energy for low-carbon electricity generation, as well as for other applications, including hydrogen production. That assessment is contained in the latest (28th) edition of Uranium—Resources, Production and Demand, a global, biennial reference prepared jointly by the OECD Nuclear Energy Agency and the International Atomic Energy Agency.

The publication adds, however, that the impact of the COVID-19 pandemic and recent reductions in uranium production and exploration could affect available supplies, suggesting that timely investment in innovative mining and processing techniques would help assure that uranium resources are brought to market when needed.

The U.S. Congress has failed to uphold its promise to fully fund Yucca Mountain, in Nevada, as a permanent repository for spent nuclear fuel, Rep. Michael C. Burgess (R., Texas) writes in an op-ed article published on December 8 in the Dallas Morning News.

More than three decades after passing the Nuclear Waste Policy Act, Congress has yet to fully fund the Yucca Mountain Project. Burgess points out that while some countries have found success with reprocessing spent fuels, the fission process will always produce some amount of material that must be safely disposed, making it necessary to find a permanent solution.

To help speed the transition to clean energy that many experts say will be required to achieve global climate goals by mid-century, the International Atomic Energy Agency and International Energy Agency (IEA) have agreed to strengthen cooperation on activities involving nuclear power.

IAEA Director General Rafael Mariano Grossi and IEA Executive Director Fatih Birol on November 30 signed a memorandum of understanding, under which the two organizations will share data, statistics, energy modeling tools, policy analysis, and research, according to the IAEA on December 3. The agencies will also collaborate on publications, seminars, workshops, and webinars and increase participation in each other’s conferences and meetings of mutual interest.

The International Atomic Energy Agency has awarded fellowships to the first group of 100 female students from around the world under a new initiative to help close the gender gap in nuclear science and technology.

The Marie Sklodowska-Curie Fellowship Program, named after the pioneering physicist, was launched by IAEA Director General Rafael Mariano Grossi in March to support women pursuing nuclear-related careers.

A final report on the dry storage and transportation of high-burnup spent nuclear fuel (NUREG-2224) has been issued by the Nuclear Regulatory Commission. NUREG-2224 provides a technical basis in support of the NRC’s guidance on adequate fuel conditions as it pertains to hydride reorientation in the cladding of high-burnup spent fuel (over 45 gigawatt-day per metric ton uranium).

NUREG-2224, “Dry Storage and Transportation of High Burnup Spent Nuclear Fuel,” was made publicly available on November 23 on the NRC’s ADAMS website with Accession No. ML20191A321.

Construction of a new utility shaft at the Waste Isolation Pilot Plant transuranic waste repository may be put on hold after the New Mexico Environment Department (NMED) denied a request by the Department of Energy and its contractor to extend state authorization of the project. The shaft is part of WIPP’s Safety Significant Confinement Ventilation System, a $300-million project intended to allow simultaneous mining and waste emplacement activities in the geologic repository by increasing ventilation to the underground.

The NMED in April 2020 approved a request by the DOE and WIPP operator Nuclear Waste Partnership (NWP) for temporary authorization to begin construction of the utility shaft while the state reviews a modification to WIPP’s permit allowing the addition to the repository. That authorization expired on October 24, and the DOE and NWP asked for an extension of the authorization for an additional 180 days while the permit modification process continues.

Citing ongoing developments with COVID-19, Waste Management Symposia has announced that it has decided to make its 2021 Waste Management Conference a virtual event. WM Symposia has been holding its annual conference for the management of radioactive waste, nuclear decommissioning, and related topics since 1974. The conference is typically held in early March in Phoenix, Ariz.

According to the International Atomic Energy Agency, between 750,000 and 1 million metric tons of sediments are discharged into the Caribbean Sea each year. The release of sedimentation into the world’s oceans, increasingly from human activities, degrades marine environments and jeopardizes regional fishing industries.

The IAEA is supporting Latin American and Caribbean countries in monitoring and analyzing the scope and scale of sedimentation in the region by providing training on the use of the lead radioisotope Pb-210 in the sampling, monitoring, and study of growing sedimentation in the Caribbean and its effects on marine life. That training has culminated in the publication of a study in the November 2020 issue of the Journal of Environmental Radioactivity, the agency announced on November 5.
