New, smaller designs for nuclear reactors have been touted as vital for the clean energy future, but new research found they could generate more radioactive waste than conventional nuclear power plants.

The study from Stanford University and the University of British Columbia said small reactors could produce two to 30 times the amount of waste in need of management and disposal compared with typical reactors.

NuScale Power plans to build a small modular reactor near Idaho Falls.

Don Safer, co-chair of the Sierra Club Nuclear Free Campaign, said it is one of the first investigations into waste problems for the new designs.

"You can find a lot of information about all the wonderful things that they're supposed to do, but you can't find hardly any information about the waste they will create," Safer pointed out. "It's hard to get any of the technical details about the downsides of these reactors."

Nuclear reactors produce little carbon dioxide, according to the U.S. Energy Information Administration. They provide about one-fifth of the country's energy.

Rodney Ewing, professor of nuclear security at Stanford University and one of the study's authors, said there should be a greater onus on the vendors developing and receiving federal support for advanced reactors to conduct open research on the nuclear waste issue.

Commercial plants in the U.S. have produced about 88,000 tons of spent nuclear fuel, with the most radioactive waste to be stored underground for hundreds of thousands of years. However, the study's authors noted the U.S. does not have a program to develop its own underground repository.

Safer argued it is another major concern.

"It should be required by the Nuclear Regulatory Commission that before they license any of these designs, they have a full understanding of where this waste is going to go, how it's going to be stored and what the realities that we're going to be placing onto future generations are," Safer outlined.

Safer added the report should send a message to potential host communities of new reactor technologies, such as Idaho Falls and the nearby NuScale project.

"The takeaway is to ask questions about the fuel cycle, and what the waste will be and what the coolant will be, and how they're going to deal with the physical and chemical realities that those choices make," Safer concluded.

Federal officials are in Idaho to discuss where to store nuclear waste. The U.S. Nuclear Waste Technical Review Board, an independent federal agency, is holding two meetings in Idaho Falls. The first is today and will feature a workshop on the siting of radioactive waste facilities. Wednesday's board meeting will focus on the Energy Department's consent-based siting process for waste.

Don Hancock, the nuclear waste program director for the Southwest Research and Information Center, said the consent-based process fell by the wayside during the Trump administration but has become a focus again under President Biden.

"They're starting off saying we think we want to come up with a consent-based process to see if we can store spent fuel for some considerable period of time," he explained. "But people would be consenting to temporary storage as opposed to permanent disposal."

Hancock added the Obama administration decided the siting process should prioritize temporary sites rather than long-term geological storage and the Biden administration has picked up there. The public can be involved in both Nuclear Waste Technical Review Board's meetings this week, either in person or online.

Hancock noted that Boise State University was selected by the Energy Department to receive $2 million dollars to study consent-based siting. However, he added it is not clear what that means for Idaho.

"An important question that I think people of Idaho would want to know is does Boise State and their partners think that what they're doing now and what they could be doing down the line is having Idaho consent to being this kind of interim storage site?," he said.

Boise State University did not respond to a request for comment by the deadline for this story.

This summer's "Oppenheimer" movie will shine a light on development of the first nuclear weapons, but for many in southern New Mexico it is another reminder of the federal government's failure to recognize negative health effects their families have endured for generations.

J. Robert Oppenheimer, a physicist and director of New Mexico's Los Alamos Laboratory during World War II, led the research and development of the first nuclear weapons tested in the southern part of the state.

Tina Cordova, co-founder of the Tularosa Basin Downwinders Consortium, said residents were unknowingly exposed to radiation from fallout, resulting in illness, emotional and financial distress, and death.

"The Manhattan Project and the Trinity bomb changed New Mexico forever," Cordova pointed out. "Instantaneously we became basically a sacrifice zone, and the people of New Mexico have never been part of the narrative."

Cordova participated in a weekend panel discussion following a sold-out showing of the film in Santa Fe, along with Charles Oppenheimer, grandson of J. Robert Oppenheimer.

Cordova noted she has lost count of the number of relatives in New Mexico who have died from cancer, many within 10 years of the nuclear bomb testing.

"In my own family, I'm the fourth generation to have cancer since 1945," Cordova explained. "And now I have a 23-year-old niece who's the fifth generation, and my family's not unique. It's the story we hear all across the southern part of New Mexico, where people lived as close as 12 miles to the test site."

Cordova has spent the past 18 years trying to get areas of New Mexico included in the federal Radiation Exposure Compensation Act, which provides money to people who were harmed, either from uranium mining or the atomic tests. The Act currently only offers compensation to "downwinders" who live in Arizona, Nevada and Utah.

"There was an admission of guilt on the part of the government when they established the Radiation Exposure Compensation Act but it didn't go far enough," Cordova contended. "Including New Mexico, there's a lot of the American West that received regular fallout from those tests."

Concerns are growing in the west about nuclear waste transportation.

On Tuesday, the Snake River Alliance is holding a webinar on these concerns, heightened by the potential of a temporary waste facility opening in New Mexico.

Kevin Kamps is the radioactive waste specialist for Beyond Nuclear. He said these fears are combined with the recent train derailment of toxic waste in Ohio.

He said the federal government and nuclear power industry are rushing to create the New Mexico temporary waste facility.

"These dumps that are proposed are called consolidated interim storage facilities, which means it's only temporary and the waste will have to move again," said Kamps. "So it's really wrongheaded. It's going to automatically double transportation risks."

In May, the U.S. Nuclear Regulatory Commission issued a license for the temporary waste site in New Mexico.

The Biden administration says nuclear power is a key component for the country's clean energy future. However, state officials in New Mexico have voiced their opposition to the facility.

Nuclear waste also is a concern in Idaho. Experiments are starting on new nuclear reactor designs such as small modular reactors at the Idaho National Laboratory.

However, Kamps pointed out that recent research found these SMRs generate two to 30 times the amount of radioactive waste as traditional nuclear reactors.

"So another downside of all this SMR talk," said Kamps, "which unfortunately Idaho is on the cutting edge of."

Kamps said he believes the country is living on borrowed time when it comes to the potential for disaster from nuclear power.

"We really should be transitioning into a renewable energy economy in this country," said Kamps, "which is much safer, much more secure and actually much more cost effective than nuclear power."
