Nuclear Issues

The authors analyze the 1979 Three Mile Island nuclear accident and the recent back-to-back crashes of two Boeing 737 Max jets and make policy recommendations for the regulation of increasingly complex technologies.

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

With the world focused on the United States and North Korea, it’s easy to forget that every president for a quarter-century has said preventing nuclear terrorism was a national security priority. This includes the Trump administration, which identified in its Nuclear Posture Review that nuclear terrorism is one of “the most significant threats to the security of the United States.” It appears, however, despite this strong rhetoric, the administration may not be putting its money where its mouth is.

The escalating threats between North Korea and the United States make it easy to forget the “nuclear nightmare,” as former US Secretary of Defense William J. Perry put it, that could result even from the use of just a single terrorist nuclear bomb in the heart of a major city.

At the risk of repeating the vast literature on the tragedies of Hiroshima and Nagasaki—and the substantial literature surrounding nuclear tests and simulations since then—we attempt to spell out here the likely consequences of the explosion of a single terrorist nuclear bomb on a major city, and its subsequent ripple effects on the rest of the planet. Depending on where and when it was detonated, the blast, fire, initial radiation, and long-term radioactive fallout from such a bomb could leave the heart of a major city a smoldering radioactive ruin, killing tens or hundreds of thousands of people and wounding hundreds of thousands more. Vast areas would have to be evacuated and might be uninhabitable for years. Economic, political, and social aftershocks would ripple throughout the world. A single terrorist nuclear bomb would change history. The country attacked—and the world—would never be the same.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

"The partial budget blueprint released by the White House recently will put U.S. leadership in science and technology at serious risk if Congress goes along. In addition to the obvious damage that would result from the proposed $5.8 billion cut at NIH, the $2 billion cut in applied energy R&D, the $900 million cut in DOE’s Office of Science, the abolition of ARPA-E, and the research cuts at NOAA and EPA, a less immediately obvious potential casualty would be U.S. scientific cooperation with a wide variety of other countries on a wide variety of topics."

"Every president stocks the White House with people who can advise him on the economy, national defense, and foreign relations. And nearly all presidents in modern times have understood that science and technology are so central to all of those top-tier issues — and practically every other issue on the nation’s agenda — that science and technology advice in the White House is no less essential."
