The Department of Energy and Idaho National Laboratory announced this week that the sixth major core overhaul of the Advanced Test Reactor (ATR) is complete, after an 11-month outage that began in April 2021. The ATR was built as a key piece of mission support for U.S. Navy programs and first reached full power in 1969. Today it remains “the world’s largest, most powerful and flexible materials test reactor,” in the words of INL—quite a feat for a reactor that was planned over 60 years ago.
The Neckarwestheim nuclear power plant in Germany.
After offering a small shred of hope that it might be persuaded to keep its remaining power reactors in operation a bit longer to reduce its dependence on Russia for energy, Germany has opted to continue with its nuclear phaseout. The last three operating German reactors, Neckarwestheim-2, Isar-2, and Emsland, are slated for shutdown later this year.
The Fukushima Daiichi site before the accident.
Today’s #ThrowbackThursday post looks back at some of Nuclear News’s reporting on the Fukushima Daiichi accident, which was initiated 11 years ago tomorrow. The news reporting includes the initial coverage of the event from the pages of Nuclear News in April 2011 and the in-depth coverage of the 2011 ANS Annual Meeting, where special sessions focused on the accident.

The deadline for submitting comments on the Department of Energy’s request for information on using a consent-based approach to siting federal facilities for the interim storage of spent nuclear fuel is Friday, March 4.

Last week’s announcement from the Tennessee Valley Authority about its “New Nuclear Program,” which outlines the potential development of the Clinch River site near Oak Ridge National Laboratory in Eastern Tennessee, is the catalyst for this week’s #ThrowbackThursday post. The Clinch River site was originally planned to be the location for the Clinch River Breeder Reactor, a project that, at the time, was meant to be the future of the nuclear industry in the United States.

A full-scale, electrically heated prototype for the Department of Energy’s Microreactor Applications Research Validation and Evaluation (MARVEL) project was fabricated in just nine months, according to an article published by Idaho National Laboratory on January 31. The article explains in part how a team from the lab’s machine shop created the prototype.
