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.

Three CISAC scientists have joined 26 of the nation’s top nuclear experts to send an open letter to President Obama in support of the Iran deal struck in July.

“The Joint Comprehensive Plan of Action (JCPOA) the United States and its partners negotiated with Iran will advance the cause of peace and security in the Middle East and can serve as a guidepost for future non-proliferation agreements,” the group of renowned scientists, academics and former government officials wrote in the letter dated August 8, 2015.

“This is an innovative agreement, with much more stringent constraints than any previously negotiated non-proliferation framework.”

CISAC senior fellow and former Los Alamos National Laboratory director Sig Hecker is a signatory to the letter, along with CISAC co-founder Sid Drell, and cybersecurity expert and CISAC affiliate Martin Hellman.

Six Nobel laureates also signed, including FSI senior fellow by courtesy and former Stanford Linear Accelerator director Burton Richter.

The letter arrives at a crucial time for the Obama administration as it rallies public opinion and lobbies Congress to support the Iran agreement.

Unrest at Home

The March elections were the first held since the 2022 protests in response to the suspicious death of Mahsa Amini following her arrest for not wearing a hijab. The incident catalyzed the Iranian public into a movement calling for the support of “Women, Life, and Freedom,” and sparked the largest and most wide-spread public demonstrations since the Iranian Revolution of 1979. In response, the regime claims more than 80,000 protestors were arrested, and reports claim executions reached record levels.

Even with this repression, people continue to push back, says Milani.

“There are people [in Iran] who are doing what Navalny was doing in Russia on a much smaller scale, and in a much more timid way, exposing the corruption of this regime and these sites within Iran. These defiant people who keep going to prison but don't stop exposing the deep corruption of the leaders of the Iranian regime and their multi-multibillion dollar heist of property.”

Some, like Iranian women’s rights activist Bahareh Hedayati, are even so bold as to openly advocate for a regime change. Even among hard-line supporters of the regime, Milani says there is growing recognition that business cannot continue as usual. 

“In a lead editorial in the newspaper Jomhouri-e Eslami, which Khamenei himself founded, it was said that these elections were a major defeat, and unless that message was heeded, the regime is going to lose,” Milani told McFaul.
 

Trouble in the Neighborhood

The elections also came on the heels of the October 7 Hamas terrorist attacks in Israel, and the ensuing war in Gaza. While the Khamenei government initially tried to use the attacks to its advantage, Iran’s poor economy and its adamant opposition to a two-state solution has left it at odds with both the Iranian and Palestinian publics.

“Iran isn’t really standing up with Palestinians. If Iran was standing up with them in Gaza, the regime would have suggested what the majority of the Palestinians want, which is a two-state solution,” reasons Milani. 

There is a lingering question of why the U.S., and the democratic world in general, aren’t doing more to support democracy in Iran. Dr. Milani asserts that roots of the caution is two-fold: one part stemming from a perception among U.S. progressives that criticizing the Iranian regime could be viewed as Islamophobic, and the other from uncertainty over the status of Iran’s nuclear program and enrichment capabilities. 

The latter is a threat which needs to be taken seriously, says Milani.

“If you read what the Iranian officials have been saying, I think anyone has to be not paying attention if they’ve not concluded that Iran is clearly, unmistakably, threatening to go nuclear with weapons,” he cautions.
 

An Uncertain Road Ahead

There are no easy diplomatic solutions, given the breakdown of the U.S.-Iran nuclear deal and Russia’s destabilization of nuclear policy norms and saber-rattling over the war in Ukraine. Russia, a strategic partner of Iran, is unlikely to be helpful in cooling such tensions, says Milani. But China might.

“I think China can make the regime understand,” says Milani. “Russia can work with the regime in espionage. Russia can help them in threatening dissidents. But Russia can’t have the kind of economic muscle that the regime needs to get out of this pipeline. That will only be China.”

While uncertainties about the future remain both within Iran and in regards to the consequences of its geopolitical influence, Milani is certain the tide is turning:

“These events and this election are as clear an indication as I've ever seen that the great majority of the people of Iran don't want this regime. They might not be clear on how they want to get rid of it and who they want to bring in, but clearly this has been a historic defeat.”

Amidst evolving geopolitical shifts, the foundation of U.S. nuclear deterrence, forged in the crucible of the Cold War, faces a new set of challenges. The principle of mutually assured destruction (MAD), once the bedrock of deterrence, is now being tested by Russia's aggressive posturing and China's strategic advancements. In the wake of Russia's invasion of Ukraine and signals of a willingness to employ tactical nuclear weapons, questions arise about the efficacy of traditional deterrence strategies. Concurrently, China's expanding nuclear arsenal adds complexity to the equation. Do these developments mean America needs to rethink its deterrence strategy? 

In a new paper, “China’s Nuclear Enterprise: Trends, Developments, and Implications for the United States and Its Allies,” FSI Center Fellow Oriana Skylar Mastro focuses on the Chinese perspective of the equation and examines recent trends in Chinese military doctrine and their implications for U.S. deterrence strategy. Mastro’s contribution is part of a new report, Project Atom 2023: A Competitive Strategies Approach for U.S. Nuclear Posture through 2035, produced by the CSIS Project on Nuclear Issues.

A fundamental premise underlying Mastro’s analysis is that China merits distinct scrutiny differently from Russia, and that the two countries should not be considered  “nuclear peers.” Although China is indeed engaging in nuclear force modernization, Mastro contends that the nation is still adhering to its fundamental nuclear policy: minimal retaliation capability and a no-use-first pledge.

While some have been troubled by China’s turn to regional nuclear options like the DF-26, an intermediate-range ballistic missile capable of carrying both conventional and nuclear warheads, Mastro asserts that this is because “they are regional weapons lower on the escalation ladder.” Rather than trying to achieve parity with the United States, she contends that Beijing’s objective is to preserve a credible second-strike capability, which is essential to the concept of deterrence.

Instead of prescribing specific alterations to U.S. force posture or nuclear modernization, Mastro suggests that any changes in U.S. defense strategies carefully consider the impact on Chinese nuclear strategy. The key is to preserve China’s minimal retaliation capability and its pledge to refrain from initiating nuclear warfare: “the most important goal for U.S. deterrence policy should be to ensure it does not encourage a change in China’s nuclear policy and in posture.”

Other steps the United States should take, according to Castro, include preventing the “co-mingling” of nuclear and conventional weapons on vessels apart from ballistic missile submarines. This precaution aims to eliminate ambiguity and mitigate the risk of possible conflict escalation. She also believes that there may be “more costs than benefits” in the proliferation of nuclear weapons among Asian allies — South Korea, Japan, and Australia. These threaten the non-proliferation regime and increase the possibility of accidents. The answer, Mastro holds, is not deployment of U.S. nuclear weapons on foreign soil, but rather increased consultations and joint planning with allies. Such collaborative efforts could reassure allies and partners of U.S. intentions even as they have minimal impact on Chinese contingency planning.
