Abstract: As a potential measure of mitigating the contribution of fossil fuel emissions to global warming, carbon dioxide (CO2) capture and storage (CCS) entails capturing CO2 from from large industrial sources, compressing it to a dense supercritical form (scCO2), injecting it deep into suitable reservoirs, and storing it permanently. After 20+ years of research on CCS, including various applied studies involving pilot and demonstration projects, many stakeholders believe that the world is now ready to move from demonstration to industrial-scale implementation. Yet many hurdles remain, ranging from mostly technical nature to economic and public perception issues. This talk provides a broad overview of the decades of research on CO2 and discusses what has been learned versus what challenges remain. The presentation also elaborates on California as an interesting example for the complicated road to deployment at scale, as ambitious climate goals and generous carbon credits should provide for project economics to work, yet no California CCS project has materialized to date.

Abstract: Why do moderate majorities often fail to coordinate opposition to extremist minorities? This paper offers an explanation for the microfoundations of moderate mobilization in the face of extremist minorities using the case of Islamist extremism in Indonesia. In particular, I show that moderates and extremists face asymmetric costs in the decision to voice their true preferences resulting in a coordination dilemma for moderates, which I call the “Moderates’ Dilemma.” An original survey experiment and observational data of participant behavior during two additional surveys demonstrate that moderates hide anti-violent views for fear of reputation costs and that these effects vary by individuals’ sensitivity to reputation costs and degree of uncertainty of others’ attitudes. These findings suggest that over 16 million Indonesians may be hiding moderate preferences and have significant implications for countering violent extremism policies globally.

Abstract: Artificial intelligence (AI) is rapidly improving. The opportunities are tremendous, but so are the risks. Existing and soon-to-exist capabilities pose several plausible extreme governance challenges. These include massive labor displacement, extreme inequality, an oligopolistic global market structure, reinforced authoritarianism, shifts and volatility in national power, and strategic instability. Further, there is no apparent ceiling to AI capabilities, experts envision that superhuman capabilities in strategic domains will be achieved in the coming four decades, and radical surprise breakthroughs are possible. Such achievements would likely transform wealth, power, and world order, though global politics will in turn crucially shape how AI is developed and deployed. The consequences are plausibly of a magnitude and on a timescale to dwarf other global concerns, leaders of governments and firms are asking for policy guidance, and yet scholarly attention to the AI revolution remains negligible. Research is thus urgently needed on the AI governance problem: the problem of devising global norms, policies, and institutions to best ensure the beneficial development and use of advanced AI.

This problem can be broken into three complementary research clusters:

1. The technical landscape: What are the trends and possibilities in AI capabilities? What are their likely consequences? What are the externalities from AI, and how can they best be addressed?
2. AI politics: Who are the relevant actors, what are their interests, and what can they do? What is the nature of the conflict and cooperation challenges that they are likely to face? How can they overcome dangerous conflictual dynamics, in particular an international arms race?
3. AI governance: Given our understanding of the technical landscape and AI politics, what options are available to us for global governance of AI and what should we work towards?

Work on the AI governance problem must draw on the full body of social science and policy expertise. Solutions are needed by an unknown, but plausibly impending, deadline.

Abstract: Mainland China has undergone a rapid development of nuclear power during the last two decades. The reactors under construction or soon to be constructed there include some of the world's most advanced models. While the average age of the workforce in China’s nuclear industry is still in the early 30s, China has already become largely self-sufficient in reactor design and construction, as well as other aspects of the fuel cycle. They have made full use of western technology while adapting and improving it, and now have set up a “go global” policy for exporting nuclear technology including heavy components to the rest of the world that may seem to be a strong competition to the US nuclear power industry.

Abstract: Freshwater scarcity is expected to increase over the coming decades due to population growth, migration to urban centers in water-scarce regions, and climate change. Increased scarcity will in turn drive price increases and potential for conflict. The ability of a country to equitably deliver freshwater may thus be the difference between survival and peace or war. Past solutions have relied upon massive water projects that convey freshwater from water-rich to water-scarce regions, but such strategies are energy intensive, costly, and contentious when political boundaries are crossed. Seawater desalination can be even more energy intensive, and is constrained to near-ocean locations. By contrast, reuse of treated water creates local supplies that offset demand for imported water. In the developed world, such systems are typically add-ons to existing centralized treatment plants, and purified water is pumped from these facilities to local users. In the developing world, the costs of such systems are prohibitive, and a new approach is needed. What might be done with mass-produced modular systems equipped with accurate and rapid monitoring technology? What would be the obstacles and the pay-offs?

Abstract: The safety of a nuclear and any complex system is enhanced by analyzing failures and incorporating the lessons learned into ongoing and future activities.

The triad of hardware, software, and human factors drives nuclear safety. Although each of the 14 reactor core melt incidents that have occurred involved a different reactor design, in none of these cases was the root cause a failure of a major component or an error in analysis. In the six major core melts with which I am most familiar, human factors--the interface of human beings with the hardware and software--played a surprisingly important and under-appreciated role in accident initiation or progression.

The pattern revealed by these analyses of accidents implies that human factors must be better evaluated and integrated into nuclear designs. Several examples of failure modes and the role played by human factors in these accidents are discussed.

Speaker Bio: Milton Levenson started his nuclear work on the Manhattan Project in January 1944. His first assignment was in the development of the barrier for the Gaseous Diffusion plant. Later that year he was transferred to what is now the Oak Ridge National Laboratory to work on chemical separations projects.

In 1948 he joined the Argonne National Laboratory as part of the Atomic Energy Agency relocation of nuclear reactor research. He eventually became Argonne’s Associate Laboratory Director for Energy and the Environment.

In 1973 he joined the newly formed Electric Power Research Institute (EPRI) as director of nuclear power. In 1980 when President Reagan appointed Kenneth Davis the Deputy Secretary of Energy, Levenson joined the Bechtel Corporation in the role vacated by Davis.

In 1990 he retired from Bechtel. He continues to consult and currently is one of the six Senior Technical Advisors (STA) to the Nuclear Explosives Division (NED) of DoE's National Nuclear Security Administration (NNSA).

Much of his career has involved safety. He was personally involved in the aftermath of six of the 14 core melt events. He was asked to take charge of the 100 technical staff assembled at TMI to provide technical support to the utility staff. He was extensively involved with Chernobyl, co-chairing with Dr. Velikov, Gorbachev's Science Advisor, a detailed review of the cause of the accident. He chaired the Argonne Safety Committee that reviewed the EBR 1 accident, the Borax 1 experiment, and the SL 1 project. He had secondary roles in connection with the Lucens and Fermi 1 accidents.

Levenson is a member of the National Academy of Engineering. He has served on 30 National Academy studies and chaired 12 of them. He is a recipient of the Robert E. Wilson Award of the American Institute of Chemical Engineering for contributions to nuclear chemical engineering.  He received a special award from the American Nuclear Society for work defining the Source Term, the basic value that largely determines the consequences of nuclear accidents.

Abstract: Over decades, assessment by the Intergovernmental Panel on Climate Change and many others has bolstered understanding of the climate problem: unequivocal warming, pervasive impacts, and serious risks from continued high emissions of heat-trapping gases. Societies are increasingly responding with early actions to decarbonize energy systems and prepare for impacts. In this emerging era of climate solutions, new assessment opportunities arise. They include learning from ongoing real-world experiences and helping close the gap between aspirations and the pace of progress. Against this backdrop, I will consider core challenges in assessment, in particular: (1) integrating diverse evidence; (2) applying rigorous expert judgment; and (3) deeply embedding interactions between experts and decision-makers. Examples span climate risks and portfolios of mitigation and adaptation responses. For climate and broader global change, the presentation will explore how transparent, high-traction assessment can support decisions about contested and uncertain futures.
