Nuclear Issues

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

Mariana Budjeryn argues that Ukraine should stand firm with its nuclear disarmament decision despite the violation of the Budapest Memorandum. The West, for its part, must reward this posture with unwavering support, communicating that Ukraine did the right thing. Instead of disparaging the Budapest Memorandum, Ukraine should use it as a framework to build a strong strategic partnership with the United States and its allies.

To ensure that the world has reliable access to the neutrons it needs, at the lowest possible cost, and to facilitate further efforts to minimize and eventually eliminate civilian use of highly enriched uranium, we need an international mechanism to anticipate worldwide neutron needs and plan how to meet them. In essence, the 2016 National Academies’ report recommendation (which sadly remains unfulfilled even in the United States) should be internationalized.

Nuclear reactors remain a technology whose risks and benefits, potential and real, are inequitably distributed in society, temporally and geographically. The fuel that powers reactors comes from mines that have poisoned Indigenous communities and Global South nations for decades. The connection between a nation’s nuclear energy capability and its possession of nuclear weapons, though once direct and now more attenuated, nevertheless persists. And finally there are the environmental footprints of the nuclear era: its wastes. Though often described by nuclear engineers as a technically solved problem, the disposition of nuclear waste remains unresolved in most countries (Finland and Sweden are exceptions), its fate an ongoing open question, particularly in the United States. However this question may eventually be answered, nuclear waste will perhaps be the most enduring vestige of the Anthropocene.

Although nuclear reactor design is recognized as an essential skill and intellectual output of academic nuclear engineering, little attention has been paid within the discipline to the structure of the reactor design process and factors influencing design outcomes. This paper, which marks the first systematic attempt to explore the structure of the reactor design process and choices, applies methodological and theoretical tools developed within the mechanical engineering design studies field to the study of nuclear reactor design.

Proponents of “transactional” diplomacy argue that comprehensive deals to transform political relationships are unrealistic, and that zeroing in on the most pressing issue is the only way to make any tangible progress. The “grand bargainers” retort that any deal that isn’t comprehensive will face fatal opposition from important stakeholders.

Both arguments have some merit, but the perceived distinction between them is a false one: Past engagements with Iran and North Korea were premised on the hope that piecemeal transactions could provide a platform for more sweeping diplomacy. And the best nonproliferation progress has been achieved when all sides perceived diplomatic transactions as incremental steps toward broader reconciliation.

William d'Ambruoso explains why high-level engagement, built on a baseline of deterrence, lessens the chances of war and opens the way for future cooperation in North Korean–U.S. relations.

What sounded so simple during last year’s presidential campaign has turned out, like everything related to Iran, to be quite complicated.

Trump tied American jobs to endless wars in the Middle East. Biden should link them to renewed diplomacy.
