Environmental group reports rise in support for nuclear

November 22, 2021, 9:19AMANS Nuclear Cafe

A new survey of Americans’ attitudes about energy by ecoAmerica, a Washington, D.C.–based environmental nonprofit, finds notable shifts in views on several energy sources, including nuclear energy, from 2018 to 2021.

The American Climate Perspectives Survey shows that national support for nuclear increased by 10 percentage points, from 49 percent to 59 percent. (The numbers reflect both strong and tepid backing.) Broken down by party affiliation, the survey shows Republican support holding steady at 64 percent, Independent support moving from 50 percent to 61 percent, and Democratic support rising, rather dramatically, from 37 percent to 60 percent.

On July 21, Rep. Mike Levin (D., Calif.), whose district includes the San Onofre Nuclear Generating Station (SONGS), announced with Rep. Rodney Davis (R., Ill.) the formation of the bipartisan House Spent Nuclear Fuel Solutions Caucus. The caucus, according to its members, seeks to address the challenges associated with stranded U.S. commercial spent fuel and to serve as a forum for those who want to make progress on the issue, regardless of whether they have a preferred solution.

Rep. Levin talked with Nuclear News staff writer Tim Gregoire about his goals for the caucus and finding an answer to the country’s spent nuclear fuel dilemma.

Southern Company and the Department of Energy have announced an agreement to demonstrate the world’s first fast-spectrum salt reactor in collaboration with TerraPower and a host of other participants at Idaho National Laboratory. With this announcement, at least four of the DOE’s Advanced Reactor Demonstration Project awardees featuring four different coolants—helium (X-energy), sodium (TerraPower), fluoride salt (Kairos Power), and chloride salt (Southern, with TerraPower)—have announced a site and a commitment to build either a full-size demo reactor or a scaled-down experimental reactor.

Former NRC chairman Allison Macfarlane—nuclear agnostic or opponent?

Nordhaus

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.”

Microsoft: Nuclear help wanted

Microsoft, the America-based multinational technology corporation that produces computer software, consumer electronics, personal computers, and related services, is looking for a director of nuclear technologies engineering.

Published this week on LinkedIn, the job announcement states, “We are looking for a Nuclear Technologies Engineer to research methods of utilizing nuclear energy and design useful nuclear systems. You’ll monitor and report on engineering processes, including nuclear waste disposal and safety regulations. You will handle complex machinery and resolve on-site emergencies.”

The successful candidate can be based anywhere in the U.S., the announcement added.

As a spacecraft on a research mission hurtles at up to 100,000 miles per hour toward the surface of a gas giant like Jupiter, the atmospheric gases surrounding the spacecraft turn to plasma, and spacecraft temperatures increase to more than 10,000 °F.

Former NRC chairman talks nuclear with Al Jazeera

Sabga

Macfarlane

In an interview with Al Jazeera Digital, former Nuclear Regulatory Commission chairman and self-proclaimed nuclear agnostic Allison Macfarlane said that untested advanced reactor designs and the high cost of building new power plants will limit nuclear’s ability to play a critical role in fighting the climate crisis, at least in the near future.

“Almost 19 percent of the power [in the United States] right now is produced by nuclear power. That’s carbon free. That’s really helpful. We don’t want to shut that off,” Macfarlane told Al Jazeera Digital’s managing business editor Patricia Sabga. “But I live in a pragmatic, realistic world. And I don’t think, at least in the next 10 or 20 years, that nuclear power will be able to have a big impact on reducing carbon emissions because we can’t build new plants fast enough.”
