The Nuclear Regulatory Commission has denied “without prejudice” Oklo Power’s application to build and operate its Aurora microreactor in Idaho, the agency announced yesterday. The denial, according to the NRC, is due to the California-based firm’s failure to provide sufficient information on several crucial topics regarding the Aurora design.

A lethal banana disease, known as the Fusarium wilt or Panama wilt, is spreading rapidly in South America and threatening global supplies of the Cavendish banana, the world’s most popular export variety. Working with experts in the Andean countries of Bolivia, Colombia, Ecuador, and Peru, the IAEA and the Food and Agriculture Organization of the United Nations (FAO) are using irradiation and nuclear-derived techniques to combat, manage, and prevent the spread of the disease. The IAEA describes the work in a December 24 news article.

The Nuclear Regulatory Commission has proposed a $150,000 fine for apparent security-related violations at the Oyster Creek nuclear power plant in New Jersey. Oyster Creek permanently ceased operations in 2018, and ownership of the plant was transferred to Holtec Decommissioning International for decommissioning in July 2019.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The October issue focused on plant maintenance and outage management with multiple articles looking at efficient ways to deal with plant maintenance. The article below looks at the herculean effort by INL to lead a full overhaul of the Advanced Test Reactor--a task that happens about every 10 years.
Out of the frenzy of nuclear technology and engineering development at the height of the Atomic Age, a few designs stand out above the rest—designs so innovative that they would not be surpassed for years, or even decades. An example of this unsurpassed design brilliance exists in the form of Idaho National Laboratory’s Advanced Test Reactor.
“ATR is really a beautiful machine,” said Sean O’Kelly, associate lab director for the ATR Complex. “The elegant cloverleaf core and control systems were a stroke of genius that solved just about every key problem of test reactor design. The designers’ solutions to those problems give us a testing capacity and flexibility that have yet to be matched.”
