Advanced nuclear technologies are “the shard of light we need”

April 15, 2025, 12:00PMANS Nuclear Cafe

Two recent news stories—the Department of Defense’s launching of the Advanced Nuclear Power for Installations (ANPI) program and the development of prototype nuclear batteries in Japan and South Korea—are tied together in an article by London-based writer Nick O’Hara, creator of the Substack Gridlocked: Why the 21st Century is Broken and How to Fix It.

According to O’Hara, these two developments taken together “could be the shard of light we need in otherwise dark times. Because innovations in advanced nuclear technology could be critical to unlocking the path to decarbonizing our societies and combatting climate change.”

Latest Red Book stresses need for boosts in uranium development

April 10, 2025, 12:00PMANS Nuclear Cafe

The latest edition of Uranium 2024: Resources, Production and Demand, commonly known as the Red Book, reports that current uranium resources are sufficient to meet low- and high-growth nuclear capacity needs through 2050 and beyond, but that further development of resources is still required. Even if nuclear capacity remains stable at 2050 levels through the end of the century, the report noted that cumulative demand “could exceed the current identified uranium resource base of nearly 8 million tonnes by the 2080s under the low-growth demand scenario and by the 2110s under the high-growth demand scenario outlined in this edition.”

The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.

As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

Uncertainty contributes to lowest uranium spot prices in 18 months

April 2, 2025, 9:30AMANS Nuclear Cafe

A combination of plentiful supply and uncertain demand resulted in spot pricing for uranium closing out March below $64 per pound, with dips down to about $63.50 during mid-March—the lowest price in 18 months, according to tracking by analysis firm Trading Economics. Spot prices have also fallen steadily since the beginning of 2024. Meanwhile, long-term prices have held steady at about $80 per pound at the end of March, according to Canadian front-end uranium mining, milling, and conversion company Cameco.
