David Nusbaum

Associate, Project on Managing the Atom




David Nusbaum has twenty years of professional experience as a chemical engineer in the nuclear industry. Throughout his career, he has tried to combine his technical background and broad knowledge in chemical and nuclear engineering with more practical, policy-oriented work such as the development of methods for enhancing safeguards in different kinds of nuclear facilities.

"Smashing Atoms for Peace: Using Linear Accelerators to Produce Medical Isotopes without Highly Enriched Uranium"

Policy Brief

By David Nusbaum, Associate, Project on Managing the Atom

Accelerators can eventually be substituted for nuclear research reactors for the production of medical isotopes and for neutron-based research and other applications. The use of accelerators would reduce dependence on HEU and decrease the resulting risks. The United States and other countries should work together to provide the funding and exchange of information and ideas needed to speed up the development, demonstration, and deployment of technically and economically viable accelerator technologies to substitute for research reactors.

"Suspension of Nuclear Activities Is Not End of Diversion Risks"

Conference Paper

By David Nusbaum, Associate, Project on Managing the Atom

A long-standing goal of diplomacy with Iran is persuading Iran to suspend its enrichment operations while it clarifies its past activities and while negotiations proceed on a more permanent resolution to the nuclear crisis. However, there is problem in using suspension of nuclear material production as a negotiating step: The technical details of suspension have never been clearly defined. The international community needs to be aware of the diversion risks during a suspension of enrichment activities and should mitigate these risks by including the necessary verification measures during negotiations and signing of any agreement on suspension.

"Accelerate the Accelerators! Are There Alternatives to Nuclear Research Reactors?"


By David Nusbaum, Associate, Project on Managing the Atom

This seminar reviewed the alternatives to nuclear research reactors and the benefits of adopting the technology of accelerators in order to reduce dependence on enriched uranium.

"Is Suspension the Solution?"

Op-Ed, Bulletin of the Atomic Scientists

By David Nusbaum, Associate, Project on Managing the Atom

When the United States and North Korea reached agreement on nuclear matters in February, the suspension of uranium enrichment was rightly hailed as one of the arrangement's great successes, but there are no international regulations that define what suspension of nuclear activities entails or how it should be monitored and enforced. The international community needs to be aware of diversion risks during suspension of enrichment and should require the dismantlement and sealing of equipment in sensitive areas as part of suspension agreements.

"Nuclear 101: Uranium Enrichment and Plutonium Production"


By David Nusbaum, Associate, Project on Managing the Atom

Project on Managing the Atom's Nuclear 101 series presents overviews of key issues affecting the future of nuclear weapons, energy, and nonproliferation policies.

Events Calendar

We host a busy schedule of events throughout the fall, winter and spring. Past guests include: UN Secretary-General Ban Ki-moon, former Vice President Al Gore, and former Soviet Union President Mikhail Gorbachev.
