Summary of 19th WNA fuel report released

Terrestrial Energy and the Nuclear Research and Consultancy Group (NRG) have started a graphite irradiation testing program at NRG’s Petten Research Centre’s High Flux Reactor (HFR), located in the Netherlands. According to Terrestrial Energy, which is based in Ontario, Canada, the work is part of broader program of confirmatory testing of components and systems for the company’s Integral Molten Salt Reactor (IMSR), designed to produce both electricity and industrial heat.

The testing program at NRG was planned to confirm the predicted performance of selected graphite grades throughout the seven-year cycle of an IMSR core. The testing was designed in cooperation with Frazer-Nash Consultancy, and will simulate IMSR core conditions at a range of operating temperatures and neutron flux conditions.

“Our work with NRG at its Petten HFR facility is an important element of our overall IMSR test program, now well underway. The start of in-core irradiation tests speaks to our progress and comes after many months of prior work,” Simon Irish, CEO of Terrestrial Energy, said on November 12. “The NRG work also reflects an important feature of our testing strategy. That is to engage existing laboratories offering existing capabilities rather than build those in-house, a strategy that is essential for our early deployment schedule.”

Rising

Agneta Rising, outgoing director general of the World Nuclear Association, wrote in an October 27 World Nuclear News article that nuclear power is an essential part of the climate change solution, even if it is not part of the conversation in the European Union. “In many ways, the future of nuclear energy is much brighter than it has been for many years. We are evermore recognized and valued for the unique services that nuclear energy offers humanity, and I am immensely proud to have served and led our industry through these exciting times," said Rising in a farewell message that recapped her time as WNA director general.

Two projects intended to accelerate the deployment of hydrogen production technology at existing U.S. light-water reactors received the bulk of the funding announced by the Department of Energy’s Office of Nuclear Energy (NE) on October 8 under the ongoing U.S. Industry Opportunities for Advanced Nuclear Technology Development funding opportunity announcement (FOA). Out of three projects with a total value of $26.9 million, the two involving hydrogen production have a total value of $26.2 million.

The London-based World Nuclear Association (WNA) on September 23 released The World Nuclear Supply Chain: Outlook 2040, a market-oriented look at the opportunities and challenges for nuclear power plants and their supply chain, including scenarios for the evolution of nuclear energy over the next two decades.

The report provides information on nearly 300 major independent suppliers of nuclear-grade structures, systems, components, and services, as well as an up-to-date picture of ongoing and planned nuclear plant construction, decommissioning, and major refurbishment and waste management projects.

TerraPower announced on September 15 that it plans to work with Centrus Energy to establish commercial-scale production facilities for the high-assay, low-enriched uranium (HALEU) needed to fuel many advanced reactor designs.

The proposed investment in HALEU fuel fabrication is tied to a TerraPower-led submittal to the Department of Energy’s Advanced Reactor Demonstration Program (ARDP), which was created to support the deployment of two first-of-a-kind advanced reactor designs within five to seven years. TerraPower would like one of those designs to be Natrium, the 345-MWe sodium fast reactor that it has developed with GE Hitachi Nuclear Energy.

Bilbao y León

ANS member Sama Bilbao y León, currently head of the Division of Nuclear Technology Development and Economics at the OECD Nuclear Energy Agency, will succeed Agneta Rising as the World Nuclear Association’s director general, the WNA announced this morning.

Rising, who took the reins of the WNA in January 2013, is the former vice president, environment, at Vattenfall AB; cofounder and former president of Women in Nuclear; and former president of both the European Nuclear Society and Swedish Nuclear Society. The WNA said that she is stepping down at the end of October “to move to new endeavors.” Rising will continue as director general until the end of October, with Bilbao y León serving as “director general in waiting” beginning October 5.

Idaho National Laboratory’s Transient Reactor Test Facility, also known as TREAT, returned to service in 2017 after a hiatus of more than two decades. To make full use of TREAT’s capabilities, researchers at INL created the Minimal Activation Retrievable Capsule Holder (MARCH) test vehicle system, which, according to an August 26 Department of Energy press release, can cut years off the development process for nuclear fuels and materials and allow new clients, like NASA, to take advantage of TREAT’s capabilities.

Global nuclear power generation in 2019 totaled 2,657 TWh, second only to the 2,661 TWh generated in 2006, according to the World Nuclear Performance Report 2020, released yesterday by the World Nuclear Association. This is the seventh consecutive year that nuclear generation has increased, the WNA noted, with output 311 TWh higher than in 2012.

“In 2020, the world’s nuclear reactors have shown resilience and flexibility, adapting to changes in demand while ensuring stable and reliable electricity supplies,” said WNA Director General Agneta Rising.

According to a story published by the Massachusetts Institute of Technology on July 24, the capture of gaseous fission products such as krypton-85 during the reprocessing of spent nuclear fuel could be aided by the adsorption of gasses into an advanced type of soft crystalline material, metal organic frameworks(MOF), which feature high porosity and large internal surface areas that can trap an array of organic and inorganic compounds.

Uranium producers around the world have suffered through years of record low uranium prices. In 2019 the United States recorded its lowest total uranium production—174,000 lb U3O8—since the U.S. Energy Information Administration began collecting data in 1949, according to the agency’s Today in Energy analysis of July 17.

U.S. uranium producers asked the federal government to come to their aid in January 2018, and President Donald Trump created the U.S. Nuclear Fuel Working Group (NFWG) in July 2019. While the NFWG issued a report in April 2020 recommending support for the front end of the nuclear fuel cycle, uranium producers are in a waiting game once again as the U.S. House of Representatives works on Fiscal Year 2021 appropriations legislation.
