Fears mount for safety of Ukraine’s nuclear reactors amid Russian invasion

| Feb. 25, 2022

Concerns are mounting about the safety of Ukraine’s 15 nuclear reactors and the possibility of an ecological disaster in the midst of the Russian invasion.

“There are contingencies but I doubt that these power plants have prepared for a full-scale invasion,” said Mariana Budjeryn, a Ukrainian research associate with Harvard University’s project on managing the atom. “In the middle of a large scale conflict, there’s a myriad of things that could happen, for which normal, even very robust, safety procedures at a nuclear power plant [would be insufficient].”

How to Make Sure Neutrons Save Lives Instead of End Them

| May 12, 2021

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.

Reimagining Nuclear Engineering

| May 07, 2021

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.

Accidents, Paradoxes and the Epistemic Future of Nuclear Policy

| Mar. 11, 2021

When accidents, particularly nuclear accidents, occur, there is a desire, even an imperative almost, to identify the ‘root causes’ of that particular accident. This is not entirely surprising because such accidents cause existential crises sector-wide or industry-wide that reflect the desire to never repeat the mistakes that led to such a severe outcome. However, identifying the root causes of an accident is seldom possible. The causes of an accident are typically large in number and complex in relationship to each other.

Chernobyl: A Nuclear Accident That Changed the Course of History. Then Came Fukushima.

| Mar. 11, 2021

Chernobyl still stands for the world’s worst nuclear accident. The full impact of a nuclear disaster on this scale is difficult to compute, not least because the effects that count most are often those that are most difficult to count. Beyond the number of lives lost and people displaced, beyond the money spent on accident mitigation and remediation, there are long-term health, environmental, social, economic, and political consequences that defy quantification. Thirty-five years on, we are still grappling with the full extent of Chernobyl’s impact on the world. Yet in a very real sense, we live in a world shaped by Chernobyl.

Asking the Unasked Questions

| Mar. 11, 2021

Ten years after the Fukushima Daiichi nuclear disaster, the suffering of many tens of thousands of people lingers—as does the slowdown in global nuclear energy growth that followed the meltdowns. The broad impact of the disaster prompts us to ask not only how it happened, but how the world community can best prevent such disasters in the future.

Highly Enriched Shareholders Mean Disasters Down the Line: Why Utilities Like TEPCO Need New Corporate Governance

| Mar. 11, 2021

Ten years on, the lessons learned from the Fukushima Dai-ichi Nuclear Power Plant accident continue to focus on improving safety culture and regulatory oversight. However, the executive decisions that failed to prevent the disaster also demonstrate the necessity to re-examine the legal entities most often relied on for producing nuclear power: corporations.

Nuclear Safety and Security Lessons from Chernobyl and Fukushima

| Mar. 11, 2021
  1. We must learn from and remember the lessons of the past—while recognizing that Fukushima is not going to “happen again” as future accidents will have their own characteristics; while remembering the past, we must also avail ourselves of advances in seismology, climatology, engineering, etc.

Nuclear Energy, Ten Years After Fukushima

| Mar. 05, 2021

Ten years have passed since a catastrophic earthquake and tsunami damaged the Fukushima Daiichi nuclear power plant in Japan, triggering the worst nuclear accident since the Chernobyl disaster in 1986.

The accident struck at a time of renewed hope and untested optimism surrounding a new wave of nuclear-energy technologies and the part they might play in achieving a low-carbon future. It led to retrenchment, amid fresh concerns over the technological, institutional and cultural vulnerabilities of nuclear infrastructures, and the fallibility of humans in designing, managing and operating such complex systems.

A decade after the disaster, these serious questions linger, even as the climate crisis grows nearer.
