Nuclear Issues

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.

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.

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.

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.

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.

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.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."

On September 21, 2015, IAEA Director General Yukiya Amano informed the Board of Governors that one day earlier he had visited a suspect site within the Parchin Military Complex in Iran. A few days prior to Director General Amano’s visit, as foreseen in an unofficial draft Iran/IAEA agreement, Iran, took environmental samples at the suspect location. Amano said in a public statement that access to the site was important in order to “clarify issues related to possible military dimensions to Iran’s nuclear program.” However, the manner in which environmental samples were taken raises troubling precedents for both the IAEA’s investigation into Iran’s past work on nuclear weapons and the verifiability of the long term nuclear deal, the Joint Compreheansive Plan of Action (JCPOA).

On June 23 and 24, twenty five experts met at Harvard University’s Kennedy School of Government under the auspices of the Geopolitics of Energy Project at the Belfer Center for Science and International Affairs. The group, which included experts from academia, the financial sector, government, and the energy industry, spent an evening and the following full day discussing and debating the possible energy implications of a nuclear deal between the P5+1 and Iran.
