Aalo Atomics discusses the road ahead
Yasir Arafat, president and chief technology officer of Aalo Atomics, participated in the first day of sessions at the Nuclear Regulatory Commission’s annual Regulatory Information Conference (RIC). There, he recapped some of the company’s recent milestones and revealed new details on what lies ahead for Aalo.
His attendance at the event coincided with a number of announcements in the past two weeks. Those announcements covered new contracts with Global Nuclear Fuel and Baker Hughes, the release of a new strategic roadmap, the completion of fuel enrichment by Urenco USA, and a new approval from the Department of Energy.

The purpose of this technical note is to evaluate the discharged fuel of breed-and-burn (B&B) reactors. The discharged burnup in a B&B core can be high, and there is a concern that as decay heat increases, handling after a shutdown might be difficult. Because discharged fuels contain a number of plutonium nuclides, the potential for proliferation is also a concern. Moreover, radiotoxicity levels are an issue for geological disposal. As reference cores, two stationary wave reactor (SWR) cores proposed in our previous studies were used. The SWR is a special type of B&B reactor. Discharged fuels of the two SWR cores were evaluated by comparing them to a pressurized water reactor (PWR) and a fast breeder reactor. The discharged fuels of both SWR cores were not significantly worse than the reference PWR, even though the burnup was about 2.6 to 7.0 times higher.
