Ukraine Conflict: How Dangerous Is Russia's Nuclear Plant Attack?

| Mar. 04, 2022

Russian forces have seized the largest nuclear plant in Europe, Ukrainian authorities say. It comes hours after a fire broke out at the Zaporizhzhia plant following a Russian attack. The fire has since been extinguished, and officials say the site is safe but Western powers have condemned Russia for what they called a "horrific" and "reckless" act, and Ukrainian President Zelensky says the attack could have caused "six Chernobyls". Mariana Budjeryn is a Research Associate with the Project on Managing the Atom  at the Harvard Kennedy School Belfer Center. She says that as far as we know, the shelling hit a number of facilities but that the flow of electricity must be kept constant to allow the fuel to keep cooling. She goes on to say that reactors are protected to withstand a certain level of impact, but none have been designed to withstand sustained artillery fire. She says there is concern that at this level of hostilities, there is a risk of a serious nuclear accident, or one that is planned to stop the war quickly and on Russia conditions. "You can't just hit a switch on a nuclear reactor - there are still a number of procedures that have to be followed quite closely to keep that reactor safe."

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].”

Enabling a Significant Nuclear Role in China’s Decarbonization

| Dec. 02, 2021

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

A Viable Nuclear Industry

| Summer 2021

Aditi Verma and Denia Djokić call for rethinking our collective approach to the benefits and risks of nuclear technology—a call that is crucial and timely. As humanity confronts the catastrophic consequences of climate change, questions related to the viability of nuclear energy to achieve a decarbonized world abound. The authors, however, push the boundaries of the current conversation by arguing that what is required to make nuclear energy “viable” for the twenty-first century is much more than just an exercise in technological development.

Risks to Persian Gulf Cities from Spent Fuel Fires at the Barakah and Bushehr Nuclear Power Plants

Interest in nuclear power has grown in some Middle Eastern states despite poor economics, seismic activity, and attacks on nuclear facilities in the region. This article assesses risks from cesium-137 release and dispersal from spent nuclear fuel fires at Barakah in the United Arab Emirates and Bushehr in Iran to public health, the water supply, and the food security of major Persian Gulf cities. Doha, Dammam, Al-Hofuf, and Manama are most at risk of receiving 1.5 MBq/m2 for a spent fuel fire at Barakah, while a spent fuel fire at Bushehr could affect Shiraz, Ahvaz, Basrah, and Kuwait City, albeit at lower probabilities. Absent a decision to end nuclear power in the region, options for reducing the potential risks of spent fuel fires on Persian Gulf populations include the timely transfer of spent fuel from pools into safer dry cask storage, multilateral disaster-response planning, and a commitment not to attack nuclear facilities.

The Nuclear, Humanities, and Social Science Nexus: Challenges and Opportunities for Speaking Across the Disciplinary Divides

| Aug. 07, 2021

The central aim of this special issue is to explore how research findings and insights from the humanities and social sciences can be used to shape and meaningfully inform the work of practitioners and policy makers in the nuclear energy sector and its corresponding areas of research and practice—all of which presently, in many ways, simultaneously face several challenges and opportunities and find themselves at a crossroads.

Increase in Frequency of Nuclear Power Outages Due to Changing Climate

| July 05, 2021

Climate-related changes have already affected operating conditions for different types of energy system, in particular power plants. With more than three decades of data on changing climate, we are now in a position to empirically assess the impact of climate change on power plant operations. Such empirical assessments can provide an additional measure of the resilience of power plants going forward. Here I analyse climate-linked outages in nuclear power plants over the past three decades. My assessment shows that the average frequency of climate-induced disruptions has dramatically increased from 0.2 outage per reactor-year in the 1990s to 1.5 in the past decade. Based on the projections for adopted climate scenarios, the average annual energy loss of the global nuclear fleet is estimated to range between 0.8% and 1.4% in the mid-term (2046–2065) and 1.4% and 2.4% in the long term (2081–2100).
