Argonne model improves nuclear plant maintenance planning

Researchers at Argonne National Laboratory have developed a multiphysics simulation modeling tool to predict how feedwater heater tubes in a nuclear power plant break down over time. The model, which has the potential to improve maintenance schedules and save operating costs at nuclear facilities, is described in a paper titled “Numerical Analysis with Experimental Validation of Tube Fatigue Failure in Feedwater Heaters,” published in a recent issue of Engineering Failure Analysis.

Nano Nuclear releases RFI for Loki lunar ambitions

Nuclear power in space is back in the news for the second time in recent weeks as microreactor start-up Nano Nuclear has released a request for information to identify organizations that may support the company in the development of its Loki micro modular reactor. The company’s goal is eventual deployment of Loki on the lunar surface. Go deeper on Nuclear NewsWire.

IAEA, PNNL test new uranium enrichment monitor

A uranium enrichment monitor developed by a team at Pacific Northwest National Laboratory will soon be undergoing testing for nonproliferation applications at the International Atomic Energy Agency Centre of Excellence for Safeguards and Non-Proliferation in the United Kingdom. A recent PNNL news article describes how the research team, led by nuclear physicist James Ely, who works within the lab’s National Security Directorate, developed the UF6 gas enrichment sensor (UGES) prototype for treaty verification and other purposes.

Nuclear trivia—reveal

The answer: California has been home to seven commercial power reactors, some key details of which are highlighted below: Humboldt Bay-3 was California’s first commercial reactor. The BWR entered operation in 1963 and was shut down for refueling in 1976. After that shut down, an economic analysis found that restarting the unit would not be cost effective. In 1983, PG&E announced it would decommission the plant. The site was officially released for unrestricted use in 2021. San Onofre-1 was next to enter operation in 1968, The PWR was then followed by SONGS-2 and -3 in 1983 and 1984, respectively. SONGS-1 was closed in 1992, with -2 and -3 shuttering in 2013—a moment that was captured in great detail on Nuclear NewsWire. Rancho Seco began its life in between the opening of SONGS-1 and -2—the single-unit PWR entered operation in 1975 and closed in 1989. It maintains the distinction of being California’s shortest-lived NPP, with only a 14-year lifespan. (While it’s true that Humboldt Bay ran for 13 years, it wasn’t officially shut down for another six years.) Diablo Canyon-1 entered commercial operation in 1977 in Avila Beach; Unit 2 entered operation four years later. The two PWRs at the site are California’s last remaining nuclear power plants in operation. Once slated for a total shut down by 2025, the plant now has a brighter future. As recently as December 2025, PG&E announced positive progress in its continued work to extend operations at the plant through 2030.
