U.S. Nuclear Nexus created to guide exporters of advanced nuclear technology

August 23, 2021, 12:00PMNuclear News

Companies, universities, and national laboratories across the United States are working together to develop and demonstrate advanced nuclear technologies. To deploy those technologies on a global scale and maximize U.S. efforts to combat climate change, technology developers eyeing the export market must navigate rules and recommendations designed to ensure that international safeguards, security, and nonproliferation standards are met. Understanding and, where appropriate, integrating these standards early in the development process is crucial for streamlining export and technology deployment.

At the box office or streaming at home, it’s fear, not truth, that sells. The laws of physics are swept aside, apocalypse is inevitable, and superpowered heroes wait until the last possible second to save the universe. It can make for great entertainment, but in the real world we need to stick with science over science fiction and be wowed by engineering, not special effects.

The truth is, science and innovation are incredible in their own right. From communications and machine learning to space travel and medical advances, technology is evolving in hyperdrive to solve real problems. With climate change and global warming here on earth, we don’t have to go looking for trouble in a galaxy far, far away.

The Department of Energy announced in 2020 its approval of Critical Decision 1 for the Versatile Test Reactor (VTR) project, a one-of-a-kind scientific user facility that would support research and development of innovative nuclear energy and other technologies. The decision was well received by the nuclear energy community—after all, the DOE’s Nuclear Energy Advisory Committee had studied and reported on the need for the VTR and found strong support for the project among reactor developers, federal agencies and national laboratories, and university researchers.

The value of “fluffy” stuff

You 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.

Testing for Terrestrial Energy’s IMSR under way with research partners

November 19, 2020, 7:00AMNuclear News

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.”

The ongoing effort to convert the world’s research reactors

In late 2018, Nigeria’s sole operating nuclear research reactor, NIRR-1, switched to a safer uranium fuel. Coming just 18 months on the heels of a celebrated conversion in Ghana, the NIRR-1 reboot passed without much fanfare. However, the switch marked an important global milestone: NIRR-1 was the last of Africa’s 11 operating research reactors to run on high-enriched uranium fuel.

The 40-year effort to make research reactors safer and more secure by replacing HEU fuel with low-enriched uranium is marked by a succession of quiet but immeasurably significant milestones like these. Before Africa, a team of engineers from many organizations, including the U.S. Department of Energy’s Argonne National Laboratory, concluded its conversion work in South America and Australia. Worldwide, 71 reactors in nearly 40 countries have undergone conversions to LEU, defined as less than 20 percent uranium-235. Another 31 research reactors have been permanently shut down.
