Nuclear Issues

The head of Iran’s nuclear program says Iran has the capability to initiate mass production of advanced centrifuges on short notice. The mass production of these centrifuges (or their components) would greatly expand Iran’s ability to sneak-out or breakout to nuclear weapons capability or surge the size of its centrifuge program if the deal fails or after key nuclear limitations end. If Salehi’s statement is true, Iran could have already stockpiled many advanced centrifuge components, associated raw materials, and the equipment necessary to operate a large number of advanced centrifuges. The United States and the International Atomic Energy Agency (IAEA) need to determine the status of Iran’s centrifuge manufacturing capabilities, including the number of key centrifuge parts Iran has made and the amount of centrifuge equipment it has procured. They need to ensure that Iran’s centrifuge manufacturing is consistent with the intent of the nuclear deal as well as the deal’s specific limitations on advanced centrifuges. Moreover, the Iranian statement illuminates significant weaknesses in the Iran deal that need to be fixed.

On 24 and 25 November 2016 experts from politics and academia, including FDP Executive director Cathryn Clüver, discussed the impact of Brexit on several policy areas in a series of workshops at the Hertie School of Governance in Berlin. All events took place under Chatham House rules.

As early as the end of the Second World War it was recognized that nuclear fuel cycle technologies developed for military purposes—specifically, uranium enrichment and reprocessing—had major potential for peaceful applications but remained inherently dual-purpose, and if not controlled appropriately, could be diverted to military use. The very first issue considered by the newly founded United Nations was “the problems raised by the discovery of atomic energy.”

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.

China’s approach to strengthening the security of its nuclear weapons, materials, and facilities is important in facilitating strong global action on nuclear security. At the 2014 Nuclear Security Summit in The Hague, Chinese President Xi Jinping made commitments to strengthening nuclear security.

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

Reducing the Use of Highly Enriched Uranium in Civilian Research Reactors is a report of the Committee on the Current Status of and Progress Toward Eliminating Highly Enriched Uranium Use in Fuel for Civilian Research and Test Reactors. The committee was established by the Nuclear and Radiation Studies Board, Division on Earth and Life Studies and the National Academies of Sciences, Engineering, and Medicine. The report is the result of a congressionally mandated study (P.L. 112-239, Section 31781) to assess improvement in reducing highly enriched uranium use in fuel for civilian research and test reactors.

Belfer Center Senior Fellow William Tobey is a member of the Committee that produced the report.

Standing before the United States Congress early in March 2015, in the face of a looming deadline in the Iran and P5+1 talks over the Iranian nuclear program, Israeli Prime Minister Benjamin Netanyahu portrayed the negotiations in stark terms. Drawing a direct parallel between biblical plots to persecute Jews in pre-Islamic Persia and modern Iran’s nuclear program, Netanyahu framed Iran as nothing less than an existential threat to Israel. Anything short of a practical dismantling of Iranian nuclear infrastructure would be unacceptable. Largely perceived as an attempt to undermine President Barack Obama’s efforts to reach a negotiated settlement with Iran, Netanyahu’s actions thus proved quite contentious inside the United States.

The Joint Comprehensive Plan of Action (JCPOA) puts Iran’s nuclear program under greater scrutiny than before and reduces the likelihood of an overt dash to the bomb for the next 10 years. But the agreement contains a number of notable weaknesses—particularly regarding undeclared nuclear activity and weapons- related research—that should be mitigated by adopting stronger verification measures.
