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.”

The roles of nuclear energy as a clean energy source and in space exploration were highlighted at the recent Atoms for Humanity symposium, held October 25–26, 2023. The symposium, which was organized by Purdue’s Center for Intelligent Energy Systems (CiENS) and hosted by the university’s School of Nuclear Engineering, was held on the West Lafayette, Ind., campus in Eliza Fowler Hall.

Recent staff cuts at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP) are raising concerns among international nuclear watchdogs.
Ahead of his visit to the plant on February 7, International Atomic Energy Agency director general Rafael Mariano Grossi told the Associated Press that he will focus on the impact of personnel reductions, especially while Russia has denied access to employees of Ukraine’s nuclear operator, Energoatom.

The long-awaited fourth unit at Plant Vogtle has hit another delay.
Atlanta-based Southern Co. announced last week that vibrations in the cooling system in Unit 4 require additional work that will push the reactor’s start date from the first quarter this year to the second quarter. The company said the problem is already fixed, but there is too much additional testing needed to meet a first quarter deadline.

The Department of Energy’s Office of Environmental Management announced last week that, for calendar year 2023, the department’s Waste Isolation Pilot Plant (WIPP) had its best shipment performance in 10 years, having received 489 transuranic (TRU) waste shipments from generator sites throughout the country. For comparison, WIPP received only 272 shipments in 2022.

According to the Council on Radionuclides and Radiopharmaceuticals, more than 82,000 nuclear imaging procedures using nuclear medicine are performed throughout the world every day. To administer these vital medical procedures, radiopharmaceutical companies and hospitals rely on a handful of producers of medical radioisotopes.

The state of Massachusetts is looking to require Holtec, the owners of the Pilgrim nuclear power plant, to analyze water evaporation at the plant for potential air pollution as the unit is decommissioned.
At a hearing this week with a state Department of Environmental Protection panel, officials said that more study is needed on nonradioactive contaminants in about 1 million gallons of water that Holtec has proposed discharging into Cape Cod Bay.
