As the country looks to decarbonize, nuclear’s popularity climbs to the highest level in a decade:

A Gallup survey released in late April found that 55 percent of U.S. adults support the use of nuclear power. That's up four percentage points from last year and reflects the highest level of public support for nuclear energy use in electricity since 2012.

[...] Nuclear energy has historically been a source of immense controversy. A series of high-profile nuclear accidents and disasters, from Three Mile Island in 1979 to Chernobyl in 1986 to Fukushima in 2011, have raised safety concerns — even though the death toll from fossil fuel power generation far outstrips that of nuclear power generation. Several government nuclear programs have also left behind toxic waste that place disproportionate burdens on Indigenous communities.

But nuclear power doesn't produce carbon emissions, and it's more consistent and reliable than wind and solar energy, which vary depending on the weather. For these reasons, the Biden administration has identified nuclear energy as a key climate solution to achieve grid stability in a net-zero future. The administration is pushing for the deployment of a new generation of reactors called "advanced nuclear": a catch-all term for new nuclear reactor models that improve on the safety and efficiency of traditional reactor designs.

In a recent report, the Department of Energy found that regardless of how many renewables are deployed, the U.S. will need an additional 200 gigawatts of advanced nuclear power — enough to power about 160 million homes — to reach President Joe Biden's goal of hitting net-zero emissions by 2050.

Gallup has tracked several swings in public opinion since first asking about nuclear in 1994. From 2004 to 2015, a majority of Americans favored nuclear power use, with a high of 62 percent in support in 2010. But in 2016, the survey found a majority opposition to nuclear power for the first time. Gallup speculated that lower gasoline prices that year may have "lessened Americans' perceptions that energy sources such as nuclear power are needed." In recent years, views on nuclear power had been evenly divided until the latest poll, conducted between March 1 and 23.

The new poll found that 62 percent of Republicans support the use of nuclear power, compared to 46 percent of Democrats. The support from Republicans is likely driven by "a focus on energy independence, supporting innovation, supporting American leadership globally, and supporting American competition with folks like China and Russia specifically in terms of the nuclear space," said Ryan Norman, senior policy advisor at the center-left think tank Third Way.

[...] In addition to the Department of Energy's modeling, the International Energy Agency's Net Zero by 2050 scenario found that in order to fully decarbonize the global economy, worldwide nuclear power capacity would need to double between 2022 and 2050.

In Congress, nuclear power has enjoyed some rare moments of bipartisan support. Lawmakers from both sides of the aisle have joined forces to pass a few successful pro-nuclear laws. The 2021 bipartisan infrastructure law injected $6 billion toward maintaining existing nuclear power plants. And while the 2022 Inflation Reduction Act was an entirely Democratic effort, it included a technology-neutral tax credit for low-carbon energy that can be used for nuclear power plants. The climate spending law also allocates millions in investments for advanced nuclear research and demonstration.
