Nuclear Issues

The risks of nuclear escalation between the U.S. and China or Russia are greater than ever given the possibility of misinterpreted cyber espionage and military strikes against early warning systems. What can be done to reduce this risk?

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.

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.

The 2016 Nuclear Security Summit (NSS) in Washington D.C. on 1 April issued a seven-page Action Plan in Support of the International Atomic Energy Agency (IAEA). It contains steps that the summit participants commit themselves to taking and those they “advocate” the Agency “pursue”. In endorsing this plan, 2016 Summit participants focused more detailed attention on the IAEA than those who participated in the previous four nuclear security summits.

The history of nuclear security has been described as an example of “punctuated equilibrium” -- long periods of inaction and complacency followed by events that catalyze action. U.S. history is rife with examples where the discovery of vulnerabilities or major incidents led agencies to strengthen nuclear security requirements.

Senior Fellow William Tobey testified on March 17, 2016, before the Senate Foreign Relations Committee on "Reviewing the Administration’s Nuclear Agenda."

Situated in a difficult neighborhood, New Delhi has laid strong emphasis on both nuclear safety and security for a couple of decades now. Almost three decades of state-sponsored terrorism and insurgencies of varying scale and proportion within India have meant that security of nuclear materials and installations has been a great worry to India’s security and atomic energy establishments. India’s concerns even predate the Western focus on WMD terrorism, which gained prominence only after the 9/11 terrorist attacks in the United States.  Unfortunately, India’s excessive caution and secrecy in the nuclear arena has led the world to assume that India does not pay much attention to this issue or that it has inadequate security, which is far from the truth.

Olli Heinonen, Senior Fellow at the Belfer Center for Science and International Affairs, writes that despite the general lack of cooperation from Iran, the IAEA has produced a successful comprehensive report detailing Iran's nuclear activities. However he notes that Iran's noncompliance has hampered the final determinations, and so further investigation and intelligence operations should be conducted to determine the extent of Iranian nuclear activity.

The International Atomic Energy Agency released its “final assessment” yesterday of the possible military dimensions of Iran’s nuclear program.

In prisons as in nuclear facilities, employees are tasked with guarding something highly dangerous in high-stress environments. Both face high costs in the event of failure, and both are especially vulnerable to complacency and insider threats. Given these parallels, two inmates’ dramatic break-out from a New York prison in early June offers nuclear security practitioners valuable insights into how to avert an equally dramatic (and potentially much more consequential) breech.
