The United States has a growing inventory of spent nuclear fuel from commercial power plants that continues to accumulate at reactor sites around the country.

In addition, the legacy waste from U.S. defense programs remains at Department of Energy sites around the country, mainly at Hanford, WA, Savannah River, SC, and at Idaho National Laboratory.

“The processing and handling of waste is slow to stopped and in this environment the pressure has become very great to do something.”

Currently, more than seventy thousand metric tons of spent nuclear fuel from civilian reactors is sitting in temporary aboveground storage facilities spread across 35 states, with many of the reactors that produced it shut down.  And U.S. taxpayers are paying the utilities billions of dollars to keep it there.

Meanwhile, the deep geologic repository where all that waste was supposed to go, in Yucca Mountain Nevada, is now permanently on hold, after strong resistance from Nevada residents and politicians led by U.S. Senator Harry Reid.

The Waste Isolation Pilot Plant in Carlsbad New Mexico, the world’s first geologic repository for transuranic waste, has been closed for over a year due to a release of radioactivity.

And other parts of the system, such as the vitrification plant at Hanford and the mixed oxide fuel plant at Savannah River , SC, are way behind schedule and over budget.

It’s a growing problem that’s unlikely to change this political season.

“The chances of dealing with it in the current Congress are pretty much nil, in my view,” said former U.S. Senator Jeff Bingaman (D-NM).

“We’re not going to see a solution to this problem this year or next year.”

The issue in Congress is generally divided along political lines, with Republicans wanting to move forward with the original plan to build a repository at Yucca Mountain, while Democrats support the recommendations of the Blue Ribbon Commission on America’s Nuclear Future to create a new organization to manage nuclear waste in the U.S. and start looking for a new repository location using an inclusive, consent-based process.

“One of the big worries that I have with momentum loss is loss of nuclear competency,” said David Clark, a Fellow at the Los Alamos National Laboratory.

Meanwhile, other countries are moving ahead with plans for their own repositories, with Finland and Sweden leading the pack, leaving the U.S. lagging behind.

So Ewing decided to convene a series of high-level conferences, where leading academics and nuclear experts from around the world can discuss the issues in a respectful environment with a diverse range of stakeholders – including former politicians and policy makers, scientists and representatives of Indian tribes and other effected communities.

“For many of these people and many of these constituencies, I’ve seen them argue at length, and it’s usually in a situation where a lot seems to be at stake and it’s very adversarial,” said Ewing.

“So by having the meeting at Stanford, we’ve all taken a deep breath, the program is frozen in place, nothing’s going to go anywhere tomorrow, we have the opportunity to sit and discuss things. And I think that may help.”

Former Senator Bingaman said he hoped the multidisciplinary meetings, known at the “Reset of Nuclear Waste Management Strategy and Policy Series”, would help spur progress on this pressing problem.

“There is a high level of frustration by people who are trying to find a solution to this problem of nuclear waste, and there’s no question that the actions that we’ve taken thus far have not gotten us very far,” Bingaman said.

“I think that’s why this conference that is occurring is a good thing, trying to think through what are the problems that got us into the mess we’re in, and how do we avoid them in the future.”

The latest conference, held earlier this month, considered the question of how to structure a new nuclear waste management organization in the U.S.

Speakers from Sweden, Canada and France brought an international perspective and provided lessons learned from their countries nuclear waste storage programs.

“The other…major programs, France, Switzerland, United Kingdom, Canada, they all reached a crisis point, not too different from our own,” said Ewing.

“And at this crisis point they had to reevaluate how they would go forward. They each chose a slightly different path, but having thought about it, and having selected a new path, one can also observe that their programs are moving forward.”

France has chosen to adopt a closed nuclear cycle to recycle spent fuel and reuse it to generate more electricity.

“We also reduce the toxicity because…we are removing the plutonium. And finally, we are conditioning the final waste under the form of nuclear glass, the lifetime of which is very long, in the range of a million years in repository conditions.”

Clark said that Stanford was the perfect place to convene a multidisciplinary group of thought leaders in the field who could have a real impact on the future of nuclear waste storage policy.

“The beauty of a conference like this, and holding it at a place like Stanford University and CISAC, is that all the right people are here,” he said.

“All the people who are here have the ability to influence, through some level of authority and scholarship, and they’ll be able to take the ideas that they’ve heard back to their different offices and different organizations.  I think it will make a difference, and I’m really happy to be part of it.”

Ewing said it was also important to include students in the conversation.

“There’s a next generation of researchers coming online, and I want to save them the time that it took me to realize what the problems are,” Ewing said.

“By mixing students into this meeting, letting them interact with all the parties, including the distinguished scientists and engineers, I’m hoping it speeds up the process.”

Professor Ewing is already planning his next conference, next March, which will focus on the consent-based process that will be used to identify a new location within the U.S. for a repository.

A Pivotal Moment for Climate Policy

In early May, Israel faced its second major wildfire in a month, as flames tore through the woodlands around Jerusalem, forcing the shutdown of the central region and the cancellation of Independence Day celebrations. Conference Chair, Professor Alon Tal, Visiting Fellow in Israel Studies and a leading environmental advocate, explained that once a rare occurrence, such fires have become far more frequent, reflecting a broader international pattern.

“In the past, fires of this magnitude maybe happened once a decade,” Tal noted. “But like California, Israel’s fire service now reports a tripling of high-risk fire days — ultra-dry conditions paired with high winds. This is an international phenomenon. This past year, Canadian fires destroyed 45 million acres of woodlands — seven times the annual average. Israel has received a wake-up call about the impacts of the climate crisis.”

Across two days of programming, the conference will bring together 25 Israeli experts to discuss potential solutions alongside colleagues from Los Angeles and California. “This is not just a policy conversation. This is about how we prepare our communities for an uncertain future,” Tal said. “Both Los Angeles and Tel Aviv are confronting real environmental risks, but they also have the innovation ecosystems and civic infrastructure needed to respond creatively. We have a lot to learn from studying them side by side.”

Comparing Los Angeles and Tel Aviv offers scholars and policymakers unique insights, Tal believes. “These are two of the most creative cities in the world. They both have thriving tech sectors and liberal city governments with resources and professional expertise. At the same time, they face comparable challenges: they are both dryland cities on rising coastlines, where heat waves are becoming more treacherous. Bringing their top experts together at Stanford has tremendous merit.”

Rethinking Climate Governance at the City Level

Tal emphasized that local governments are increasingly bearing the burden of climate adaptation, especially in societies marked by inequality and demographic complexity. “The changing climate brings new challenges that cities need to be ready for. And they aren’t,” he said. “Most people live in cities — they need the tools (and the budget) to reduce new risks. The LA fires have left enormous human suffering in their wake, just like the climate-driven floods in New Orleans, Houston, and New York City did. So, the question is: what steps should cities take proactively to avert disasters and maintain stability?”

While Tal emphasized the immediate environmental threats, Larry Diamond, Mosbacher Senior Fellow in Global Democracy at the Freeman Spogli Institute for International Studies (FSI) and director of the Visiting Fellows in Israel Studies program, framed the discussion within a broader governance context. “It is often said that ‘all politics is local,’ and there is a policy corollary to that. While we need national policies and international coordination to reduce fossil fuel emissions and accelerate the transition to renewable energy, the challenges of climate adaptation and resilience are also deeply local and must be met at that level. This is a great opportunity for all of us to learn from two cities on the front lines of the challenge in our respective countries — Tel Aviv and Los Angeles.”
 

A Vision for Collaborative Learning

The event also reflects the broader goals of Stanford’s Visiting Fellows in Israel Studies program, launched in 2023 to foster cross-disciplinary analysis of Israel and its unique position as a regional influence and geopolitical actor. The program appoints an Israel-based scholar to serve as a visiting fellow at FSI for a recurring three-year term. The fellow will teach courses related to some aspect of Israel’s politics, society, economy, modern history, technological development, and/or regional or international relations, as well as advise students and collaborate with faculty interested in Israel and the Middle East.

Diamond emphasized the significance of the conference in fulfilling the program’s mission. “One of our key goals in the Israel Studies Program is to engage scholars, policymakers, and civil society leaders in Israel, not only individually but collectively based on their expertise. And we seek to promote functional and scholarly interaction and mutual learning. This conference is a historic opportunity to advance this mission in the realm of climate resilience.”

Tal also highlighted the significance of hosting the conference at Stanford. “Stanford has become the world’s leading academic center for researching critical ecological problems like biodiversity and climate change. The Doerr School of Sustainability and the involvement of Nobel laureate Steven Chu as a keynote speaker make this an unparalleled opportunity for collaboration.”

Building a Lasting Impact

Tal hopes the conference will catalyze new approaches to addressing climate impacts. “It’s clear that new environmental conditions require new strategies and technologies. Seeing practical solutions firsthand is crucial, but they don’t matter without policies that enable cities to step up their climate mitigation game. Success stories need to be shared.”

The conference outcomes will be documented in a special issue of the academic journal Sustainability, ensuring that insights resonate beyond the event itself. “By focusing on urban policies and highlighting both successes and failures, we aim to chart pathways for cities to live with global warming while mitigating emissions to address the root causes,” Tal said.

Diamond further expressed his hopes for the conference’s impact. “We hope participants will not only take away specific ideas and strategies from the two cities and countries but also connections that can be of mutual practical value going forward. We want to underscore that Israel and California, with their similar climates and start-up cultures, have a particularly rich set of possibilities for collaboration and mutual learning.”
