Nuclear energy offers a pairing of high capacity factors and low carbon emissions unrivaled by other power sources, and advanced reactors and small modular reactors (SMRs) hold promise to deliver that power with even more efficiency and versatility. Researchers in the public and private sectors, backed by government funding through programs like the Department of Energy’s Advanced Reactor Demonstration Program and Advanced Research Projects Agency–Energy (ARPA-E), are bringing that promise closer to fulfillment by engineering solutions to open questions about advanced reactor materials and fuel cycles.

On June 2, Nuclear Newswire published a letter from Jose Reyes, chief technology officer at small modular reactor developer NuScale Power, to May R. Berenbaum, editor-in-chief of Proceedings of the National Academy of Sciences, regarding a research article published by PNAS two days previous. The article, “Nuclear waste from small modular reactors,” has grabbed more than a few headlines for its claim that SMRs will actually generate more nuclear waste than a standard large pressurized water reactor.

A Stanford University–led research article on small modular reactors published Tuesday in Proceedings of the National Academy of Sciences (PNAS) is not sitting well with SMR developers or, for that matter, with much of the largely pro-SMR nuclear community.

Macfarlane

As noted by Newswire yesterday, former Nuclear Regulatory Commission chairman Allison Macfarlane describes herself as “agnostic” on the subject of nuclear energy. In the view of some, however, there is a more accurate way to describe Macfarlane’s nuclear stance.

In a November 15 blog post, Breakthrough Institute cofounder Ted Nordhaus suggests that Macfarlane can be considered a face of the modern antinuclear movement, the typical representative of which, he says, is not “a hippie with a No Nukes sign,” but rather “a highly credentialed progressive policy wonk, a lawyer, or academic, or journalist, who often claims not to be opposed to nuclear energy at all.”

Five former chairmen of the U.S. Nuclear Regulatory Commission—Stephen Burns, Allison Macfarlane, Nils Diaz, Richard Meserve, and Dale Klein—signed a letter to José Romero, Arkansas health secretary and chair of the Centers for Disease Control and Prevention (CDC) immunization advisory committee, requesting that the advisory committee update its recommendation for COVID-19 vaccine allocation guidance for the energy workforce (including nuclear energy workers).

Currently, the CDC has four phases for the COVID-19 vaccine rollout. Those phases are numbered:

• 1a (the current phase), reserved for healthcare workers and those living in long-term care facilities;
• 1b, reserved for people 75 years and older and frontline essential workers;
• 1c, reserved for persons 65 to 74 years old, those aged 16 to 64 who have high-risk medical conditions, and other categories of essential workers (this includes energy workers); and
• 2, for everyone else that was not named in the previous three phases aged 16 to 64.
