The Department of Energy announced February 7 that fuel for the MARVEL microreactor, which Idaho National Laboratory plans to host inside the Transient Reactor Test (TREAT) facility, is now being fabricated by TRIGA International, with the first fuel delivery expected in spring 2025. MARVEL operation was expected “by the end of 2024” as recently as May 2023, but that timeline had shifted by October, when the DOE said MARVEL “is expected to be completed in early 2025.” Now, according to the DOE’s latest announcement, “Fuel loading for MARVEL is anticipated to occur in 2026, with the microreactor expected to be on line by 2027.”
