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.

Earlier this month, South Korean President Yoon Suk-yeol set off alarms. In an off-the-cuff remark, he warned that Seoul might need to develop nuclear weapons—or demand redeployment of U.S. nuclear arms to the Korean Peninsula—to counter North Korean nuclear threats. In doing so, Yoon spotlighted a popular view once reserved for hawkish commentators, defense intellectuals, and former military officials. Keeping nuclear weapons out of South Korea will ultimately be a U.S. responsibility that requires addressing both the deteriorating security environment and the domestic drivers underlying Yoon’s statement.

One of the world’s foremost nuclear security and policy experts, Sig Hecker has spent much of an illustrious career working to enhance cooperation among US and Russian scientists and their governments in hopes of reducing nuclear risk. In fact, Hecker has literally edited the book on the subject, Doomed to Cooperate: How American and Russian scientists joined forces to avert some of the greatest post-Cold War nuclear dangers.

The Pentagon estimates that 600 Russian missiles have been fired at Ukrainian targets in the first 10 days of war alone. Additionally, the infamous abandoned Chernobyl nuclear plant has been seized by Russian forces and, most recently, the Zaporizhzhia Nuclear Power Station in Enerhodar has been attacked and occupied by armed Russian soldiers. Zaporizhzhia is the largest nuclear power plant in Europe and Russian projectiles started a localized fire in an auxiliary building on the site on March 3, 2020.

Russian forces have also cut off the power supply to the Chernobyl reactor and containment site. This means that spent nuclear fuel is not being cooled at the site in accordance to internationally recognized standards. The head of the Chernobyl nuclear plant has said that the back-up generators have enough fuel to power the site for 48 hours. We can only guess what might happen after that. If this were not enough, there is still ongoing shelling at a nuclear research facility in Kharkiv. The current conditions there are unknown.

Despite these chaotic circumstances, the SaveEcoBot team, in coordination with the Ministry of Environmental Protection, has put a lot of effort into radiation monitoring and informing the public about changes in background radiation. We’ve been set back in this critical work by the damages done to our monitoring equipment by Russians, but Ukrainian technicians are restoring the systems as fast as they can.

The assaults on the Chernobyl and Zaporizhzhia power plants have already had implications for the environment. The radioactive dust raised by the wheels and trucks of the Russian combat vehicles in the Chernobyl zone has raised the background radiation levels to a hundredfold excess of the normal threshold. Just imagine what chaotic attacks, with Russians shooting, firing missiles, and bombing other parts of Ukrainian territory might lead to. In Ukraine, we have a saying, “мавпа з гранатою,” which means, “Like a monkey with a grenade." Russia is playing the monkey to all of Europe.

Russia continues to assert that its forces are in Ukraine for reasons of safety and security. The takeover of Chernobyl disturbed large amounts of radioactive soil, propelling it into the air. The attack on Zaporizhzhia resulted in a fire on the site of an active nuclear plant. This is not what safety looks like. To pretend that these actions are anything but a dangerous disregard for life is an insult to all sane, rational people. We are all very lucky that none of Zaporizhzhia’s six reactors were hit by the tank shell that started that fire.

Russia, the U.S. and the UK committed 20 years ago to ensure Ukraine’s peaceful sovereignty in exchange for Ukraine giving up its nuclear weapons program. This agreement was built on the idea that Ukraine without nuclear weapons would never have cause to be the target of any attack. This assurance was guaranteed by the signers of the memorandum.

But Russia’s violent attacks have proven that a nuclear threat still exists in Ukraine. It is not a threat of Ukraine’s making, but one engineered by Russia’s own reckless assault on our civilian nuclear facilities. The consequences of this diabolical action go well beyond a potential environmental catastrophe for Ukraine; our neighbors, including Russia itself, and even countries outside of Europe could all be affected by nuclear fallout carried on high-atmosphere winds across continent and over oceans.

One way to mitigate this threat and to realize security assurances to Ukraine is to implement a no-fly zone over Ukraine. The hesitance of the EU and U.S.  to implement a no-fly zone is understandable. But at the same time, it is critically important to develop options and generate models for other types of no-fly zones beyond the proposals being discussed today. Such alternative options could be the key to helping prevent a Ukrainian tragedy not only in terms of nuclear security, but also in averting a similar tragedy to what the world witnessed in Aleppo.

To do this, Ukraine needs more military support. We have gratefully received strong military support from our allies, but even this bounty is not enough to defend our country. Stinger missiles can shoot down small, low-flying aircraft from a fairly short distance, but are useless against ballistic missiles and high-altitude bombers. We need weapons that can shoot down planes at considerable distances and altitudes, systems to detect and shoot down cruise missiles, and planes to protect our airspace. Early Russian attacks targeted our airports to deplete our air defense capabilities and frustrate our ability to get planes in the air. But we still stand. But if we want to avert a second Chernobyl or another Aleppo, we need to strengthen our air defenses.

We learned in 1939 that making concessions to tyrants is no plan for peace. Putin is a bully. Like all bullies, he will take as much as he can get while treating all harm — including environmental harm — as merely incidental. Like all bullies, he will stop only when he meets strong resistance. Putin and the Russia propaganda machine frame all attempts to stymie Russian aggression as not only a provocation, but a provocation that could trigger a nuclear response. Such veiled threats of nuclear attacks are a form of prior restraint meant to constrain Ukraine’s allies from even suggesting that the Russian invasion is improper. But we must not accept this starkly irrational framework. Nuclear weapons are weapons of deterrence, not tools to chill diplomatic criticism.

American analysts say that they expect the Russian attacks to become increasingly more brutal. Any increased risks to civilian and military targets commensurately increases risks to nuclear sites as well. And any compromised nuclear facility in Ukraine inherently becomes an international problem, not just a local one. Like Putin, radioactive fallout does not respect borders.

Just ten days ago, my life changed dramatically. I used to be a successful civil leader and entrepreneur with an innovative business. Now I sleep on the floor of an abandoned building with my gun in hand. My daughter knows exactly how the air raid siren sounds. But we are still Ukrainians. We are still Europeans. We still count on our allies. So to our allies, I say: close the Ukrainian sky. Provide us with enough weapons. We will do the rest.

As the tragedy in Ukraine unfolds before the world with each day darker than the next, Russian saber rattling with nuclear weapons is only a part of the nuclear concern. Reported increases in radiation levels at Chernobyl and fires at the Zaporizhzhia Nuclear Power Plant, the largest in Europe, with six VVER Russian reactors, are in the headlines. In fact, Ukraine has 15 reactors at four nuclear power plants, which provided about half of its electricity. As war spreads, each of these plants is at risk.

The Origins of Spies, Lies and Algorithms

When I was a professor at UCLA, I was teaching an intelligence class. On a lark, I did a survey of my students and I asked them about their spy-themed entertainment viewing habits, as well as their attitudes towards certain intelligence topics like interrogation techniques.

What I found was there was a statistically significant correlation between their spy-themed viewing habits; people who watch the show 24 all the time were far more pro-waterboarding, among other things, than students who didn't watch spy-themed entertainment.

This got me really thinking, what do people know about espionage? Where do they get this information? And what I found is that most Americans don't know anything about the intelligence community, and when you're talking about spy agencies in a democracy, that's really problematic.

The original book was going to be more of a textbook for the class I was teaching, but as I write it, so many things started to change in the intelligence community, both politically and technologically. So with that in mind, I tried to make it forward looking to where intelligence needs to go, not just backward to where it’s been.

Who are the Spies?
 

The biggest surprise for me came from the research I did on open-source intelligence and nuclear threats. If ever there was an area you would think spy agencies would have cornered the market on intelligence, it would be nuclear threats.

But what I found is that there's a whole ecosystem of non-governmental people tracking nuclear threats around the world and actually uncovering really important things. That includes some open-source nuclear sleuths here at Stanford among my colleagues at CISAC.

The more I dug into this, the more I realized that open-source intelligence and publicly available data is the ballgame in the future of intelligence. Secrets still matter; but they matter a whole lot less than they did even ten years ago.

There is so much insight that we can glean from open-source information, but the intelligence community has to figure out better ways to connect with organizations and people who are in this ecosystem.

What are the Lies?

Intelligence is about deception. We don't want our enemies to understand all of our military capabilities, for example, or what our intentions are.

But I think the technology and data revolutions of the last few decades has also changed the nature of deception. It’s gone from elites deceiving elites about where their troops are, and whether they're going to attack, to mass audience deception and this disinformation-information warfare of domestic audiences like we're experiencing here in the United States.

Understanding deception, not in a pejorative sense but as an analytic frame, is critically  important to being able to gather and analyze intelligence correctly.

The Power of Algorithms in Intelligence

We're drowning in data. The amount of data on Earth is estimated to double every two years. Think about that for a minute. It's just an astounding amount of data. And it's too much for any human to deal with.

So, if intelligence is in the business of collecting or finding needles in haystacks, the haystacks are growing exponentially. The intelligence community has to use artificial intelligence and other tools to augment human analysts. AI frees up analysts to then ask questions about things like intent, which humans can figure out much better than machines.

Imagine an algorithmic red team: you have humans that are developing assessments of what is Putin going to do in Ukraine, and you've got a red team that's just algorithms aggregating data, so that you have a sort of competitive analysis between humans and machines that can make the humans better. Those are the kinds of things that intelligence agencies need to be doing much more with AI.
