The Hanford Nuclear Site on the Columbia River in central Washington has left a complex legacy for the region.

An interactive story map imagines what a water droplet would see if it passed through the site to help young people understand how Hanford affects the environment.

Lisa Muñoz, outreach coordinator for Columbia Riverkeeper, the group behind the story map, called Hanford the "most contaminated place in the Western Hemisphere," and a threat to the waters of the Columbia. Muñoz noted the content about Hanford hazards is most often in English, although the nearby Tri-Cities area has a large Spanish-speaking population.

"So if we want everyone to have an equal opportunity to engage with the cleanup of Hanford, we really have to have clearly written materials that are accessible in their preferred language," Muñoz explained.

The Hanford Nuclear Site is decommissioned, but cleanup of the area will take generations to complete. Columbia Riverkeeper's story map, called "Water's Walk Through Hanford," is designed for middle and high school-age students.

Ivonne Romero translated the story into Spanish and said it is designed to be accessible not only to young people, but their families as well. She noted the story has stuck with her.

"I finished the translation over a month ago, but I cannot stop thinking about the importance of preserving our habitat," Romero remarked. "But also the pressing need for developing energy and creating energy in ways that are probably less deleterious to humankind."

Muñoz added it is important for young people to know about Washington's nuclear site because they are part of the river communities facing continued risks from nuclear waste.

"Hanford is a multigenerational cleanup. It's going to be there in a hundred years," Muñoz stressed. "The future of Hanford will ultimately depend on the next generation advocating for cleanup that is thorough and just."

An experimental nuclear technology project slated for testing in Idaho is raising concerns about the potential for nuclear weapons proliferation.

The Bill Gates owned company TerraPower plans to test technology known as a molten chloride fast reactor at the Idaho National Laboratory.

Former U.S. State Department officials warn the project's use of bomb-grade uranium sets a bad precedent and could encourage other countries to do similar experiments.

Ava Traverso - energy program manager for the Snake River Alliance - said with the war in Ukraine increasing fears of nuclear weapons use, the project should be reconsidered.

"As a nation, especially with the state of the world right now," said Traverso, "we should be leaning away from creating a larger possible stream of nuclear weapons production."

A spokesperson for TerraPower says the highly enriched uranium would be dealt with securely and in a location that already handles this type of material.

Traverso said the experiment presents other issues.

While the U.S. Department of Energy did assess the potential environmental effects, she said the agency should go further and release an Environmental Impact Statement - focusing especially on waste created by the project.

"If they are going to do this project, they need to do it right and they need to do right by the people of Idaho," said Traverso, "and take an actual, proper environmental assessment and not just say there's no risk because there is."

The Energy Department has said it is committed to reviving and expanding domestic nuclear energy to help the U.S. reach its goal of net-zero emissions by 2050.

However, Traverso said the transition away from fossil fuels needs to happen sooner than nuclear can provide needed energy resources.

"Starting these experiments gives people hope that oh, nuclear will solve climate change," said Traverso, "but we need real renewables now. We don't have 25 or 30 years to wait."

The U.S. Department of Energy has opened a short public-comment window on an experimental nuclear technology in Idaho.

The agency has released a draft environmental assessment for testing of what's known as "molten chloride fast reactor" technology at the Idaho National Laboratory. The technology is from TerraPower, a company owned by Bill Gates that is developing nuclear reactor designs.

Leigh Ford, executive director of the Snake River Alliance, is critical of the experiment, saying it won't benefit Idaho.

"First, nuclear energy is too slow and expensive to help with the climate crisis," she said. "The environmental assessment says that maybe 10 jobs will be created, but we're not sure if those people are from Idaho or not. And third, the waste created from this experiment will stay in Idaho."

Ford said the technology uses highly enriched uranium, which presents proliferation fears. She also said the assessment doesn't properly address impacts to ground and surface water in eastern Idaho. The Energy Department has said it's committed to reviving and expanding domestic nuclear energy to help the United States reach its goal of net-zero emissions by 2050.

Ford pointed out that the agency is giving the public a total of two weeks to react to this draft assessment.

"Fourteen days is not enough time for folks to digest this document, let alone make meaningful comments," she said. "Not to mention, we have a large rural population in Idaho that may not use email, may not have the greatest connectivity, may not be able to access this document online."

The public comment period began March 17. People have until March 31 to submit their thoughts on the assessment.

A film premiering this week tackles the potential harms of the nuclear industry.

Portland State University professor emeritus Jan Haaken directed the documentary "Atomic Bamboozle: The False Promise of a Nuclear Renaissance."

The film draws on historical lessons from the campaign to shut down the Trojan Nuclear Power Plant in Rainier, Oregon. The plant closed in 1992.

Haaken said the nuclear industry is promoting a new design concept known as small modular reactors, or SMRs. Her initial interest in SMRs was about how the industry would handle waste.

"Many of us were very attuned to the fossil fuel problem," said Haaken, "but not so much nuclear that had kind of repackaged itself as clean, cheap and promising."

Haaken said her film also focuses on areas beyond waste - such as claims the new technology is safer even as the industry pushes to streamline the regulatory process, its financial viability, and risks of proliferation.

The film premieres Sunday in Portland and also includes a speakers panel.

Executive Director of Columbia Riverkeeper, Lauren Goldberg, said the nuclear industry has positioned the sector as a solution to climate change. But she noted that experts aren't convinced the technology can be deployed fast enough to combat the crisis.

Goldberg said the industry has its eye on the Northwest, although a proposal for SMR technology at the Hanford Nuclear Site in Washington was withdrawn last week.

"For example, in the case of the proposed SMR at Hanford," said Goldberg, "the waste would have just sat along the Columbia for an unspecified amount of time, potentially hundreds of years or more. That's been what's happened with other now-defunct nuclear facilities."

Haaken said nuclear technology that has not been completely fleshed out is not a good bet for the country's energy future.

"I would put my money on renewables and engineers that are trying to figure out the grid problem and ways of developing conservation," said Haaken. "Rethinking our approach to energy with the technologies we have."
