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.
American Nuclear Society meetings and conferences are the best way to keep current with the ever changing fields of nuclear science and technology.
In addition to two national meetings per year, ANS sponsors many topical meetings which concentrate on a particular technical area. Many of these meetings are planned many years in advance and are listed here. To have a meeting listed here, it must be approved by the National Program Committee of the American Nuclear Society for inclusion on the ANS Calendar.
COVID-19 Note: ANS is continuing to monitor the COVID-19 pandemic and its impact on meetings. Please check this page often for meeting status updates.
For more than 65 years, ANS has provided a forum for advancing the state of applied nuclear science and technology. We remain committed to serving the needs of the nuclear professional community during these unprecedented times. In the coming weeks, we will be introducing a new set of digital and video tools that will enable the robust technical exchange of an ANS meeting—papers, presentations, posters, and plenaries, etc.—while ensuring the health and safety of everyone involved during the COVID-19 pandemic.
