Nuclear Issues

This Policy Brief compares and contrasts the Trump administration’s 2018 Nuclear Posture Review with past reviews and its Obama predecessor. It concludes that this review offers a much harsher assessment of the security environment; it posits a more expansive role for nuclear weapons; and proposes a substantial de-emphasis on arms control.

Effective verification will be absolutely essential to achieving nuclear disarmament. Developing effective verification may seem an impossible challenge, but there is substantial experience to build on, including IAEA safeguards and bilateral arms control processes. Examining the specific steps required to progress disarmament, we are not starting with a blank sheet, many verification missions are similar to those existing or under development today. International collaboration in developing new verification applications will contribute to the confidence and trust required to achieve the elimination of nuclear weapons.

In a televised speech on January 1, Iranian President Hassan Rouhani said that Tehran had imported 200 metric tons of yellowcake uranium and would import another 120 tons at an unspecified future date. The imports are permitted by the nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), but nonetheless significantly exceed Iran’s needs for natural (that is, unenriched) uranium over the next 15 years. Iran’s import of such high levels of uranium suggests it may be stockpiling uranium to reach nuclear breakout before the deal’s initial limitations expire in 2031.

The JCPOA permits Iran to buy natural uranium to “replenish” its stocks as it sells enriched uranium on the international market. To date, Iran has had difficulties locating a buyer for its enriched uranium stocks – unsurprising, given the current excess of commercially available enriched uranium. This, however, has not stopped Iran from buying and stockpiling more yellowcake.

North Korea just heralded the 68th anniversary of its founding by conducting its fifth nuclear test. The initial seismic recordings were larger than previously recorded activity. This, coupled with other indicators, suggests that Pyongyang’s nuclear weapons capability is accelerating.

During the 2016 Nuclear Security Summit, Belfer Center experts published reports and provided commentary and analysis on successes and continuing challenges in nuclear security around the world. Following are some actions they believe are needed to improve the security of nuclear facilities and reduce the possibility of nuclear theft and terrorism.

In the months and weeks before the 2016 Nuclear Security Summit in Washington, D.C., Belfer experts promoted a series of ideas to strengthen measures to prevent terrorists from acquiring nuclear weapons or the essential ingre­dients to make them.

The United States and Russia are the two countries with the vast majority of the world's nuclear weapons and material. In an age of global terrorism, they share both a special responsibility in ensuring that they each employ effective nuclear security systems and an understanding of the unique challenge of securing hundreds of tons of nuclear material. For two decades, the United States and Russia lived up to this responsibility by working together to strengthen nuclear security in Russia and around the globe. That ended in 2014 when Russia halted the majority of its work on nuclear security with the United States. The negative consequences of that decision could seriously affect international security and cooperation in the nuclear realm.

The Project on Managing the Atom joined the Netherlands government, the United Nations Office for Disarmament Affairs (UNODA), and the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey in convening a research symposium on the sidelines of the Nuclear Nonproliferation Treaty (NPT) 2015 review conference. The symposium, Fresh Ideas for the Future, took place on April 28 in the UN headquarters in New York City.

Matthew Bunn is a professor of practice at Harvard Kennedy School and co-principal investigator for the Belfer Center’s Project on Managing the Atom. Bunn’s research focus is on nuclear theft terrorism, nuclear proliferation, and innovation in energy technology. During the Clinton administration, Bunn served as an advisor to the White House Office of Science Technology Policy, where he played a major role in U.S. policies related to the control and disposition of weapons-usable nuclear materials in the United States and the former Soviet Union. We asked Bunn about the current crisis in U.S.-Russian relations and its impact on nuclear security.

As a young man in the small city of Ogden, Utah, Brandon Parker found himself increasingly interested in the U.S. Air Force, a service where his step-father had made his career. Recruited by the Air Force Academy to play basketball, Parker didn't initially want to become a pilot. But after his initial flight-screening program, he called his mother out of excitement to let her know that he had found exactly what he was meant to do. Until recently, Lieutenant Colonel Parker commanded a nuclear bomber unit based in North Dakota. This year, Parker a research fellow with the Center's International Security Program/Project on Managing the Atom, is conducting research on nuclear nonproliferation.
