This article is the first in a series that will examine the history of small modular reactors.

Small and medium reactors have been an integral part of the U.S. nuclear power enterprise since the early days of the industry. Many of the designs for the next generation of reactors are rooted in the designs of the 1950s and ’60s, but the development and push for deployment have gained momentum only within the last decade.

This recent momentum led a reader of Nuclear News to suggest an article reviewing the history of small modular reactors. NN staff jumped on this idea, deciding a series of articles would do better justice to such a complex and interesting topic.

The Department of Energy’s Office of Environmental Management (EM) said that heat-up of Idaho’s Integrated Waste Treatment Unit (IWTU) resumed in January. Crews began heating the IWTU in December in preparation of radiological operations, but the facility was shut down 10 days later after operators noticed a small leak of nonradioactive material inside one of the unit’s processing cells.

Located at the DOE’s Idaho National Laboratory Site, the IWTU is intended to treat Idaho’s 900,000 gallons of sodium-bearing liquid waste, converting it to a solid using a steam-reforming process.

After repairs were made to the IWTU equipment responsible for the leak, crews removed a partial obstruction that was in a line into the carbon reduction reformer, a key treatment vessel in the steam-reforming process, EM said.

The academic publishing industry—an industry that was very stable for over a century—is now experiencing a tremendous shift. Attitudes regarding the use, delivery, and costs of publication are at the center of the matter, causing publishers to investigate new publishing models. These changing attitudes require ANS to think differently to improve content offerings while continuing to generate needed revenue. The focus is on two trends: the elimination of author page charges, and the rise of open access publishing. The latter item is a relatively recent phenomenon that has been gaining traction over the past decade, especially in the medical and biology fields, but the former is an issue that has caused friction between authors and publishers for a generation or more.
