International Panel on Fissile Materials

The International Panel on Fissile Materials (IPFM) was founded in January 2006 and is an independent group of arms-control and nonproliferation experts from both nuclear weapon and non-nuclear weapon states.

The mission of the IPFM is to analyze the technical basis for practical and achievable policy initiatives to secure, consolidate, and reduce stockpiles of highly enriched uranium and plutonium. These fissile materials are the key ingredients in nuclear weapons, and their control is critical to nuclear weapons disarmament, to halting the proliferation of nuclear weapons, and to ensuring that terrorists do not acquire nuclear weapons.

Both military and civilian stocks of fissile materials have to be addressed. The nuclear-weapon states still have enough fissile materials in their weapon stockpiles for tens of thousands of nuclear weapons. On the civilian side, enough plutonium has been separated to make a similarly large number of weapons. Highly enriched uranium is used in civilian reactor fuel in more than one hundred locations. The total amount used for this purpose is sufficient to make about one thousand Hiroshima-type bombs, a design well within the potential capabilities of terrorist groups.

The Panel has been co-chaired since 2015 by Professor Alexander Glaser and Dr. Zia Mian of Princeton University and Professor Tatsujiro Suzuki of Nagasaki University, Japan. Previously, it was co-chaired by Professor Jose Goldemberg of the University of Sao Paolo, Brazil (2006-2007), Dr. R. Rajaraman (2007-2014) Professor Emeritus, of Jawaharlal Nehru University, New Delhi, India, and Professor Frank von Hippel of Princeton University (2006-2014).

Its members include nuclear experts from seventeen countries: Brazil, Canada, China, France, Germany, India, Iran, Japan, the Netherlands, Norway, Pakistan, South Korea, Russia, South Africa, Sweden, the United Kingdom, and the United States. This group of countries includes seven nuclear-weapon states and ten non-weapon states.

IPFM research and reports are shared with international organizations, national governments and nongovernmental groups. It has full panel meetings twice a year at capitals around the world in addition to specialist workshops. These meetings and workshops are often in conjunction with international conferences at which IPFM panels and experts make presentations.

Princeton University's Program on Science and Global Security provides administrative and research support for the IPFM.

IPFM's initial support is provided by grants to Princeton University from the John D. and Catherine T. MacArthur Foundation of Chicago and the Carnegie Corporation of New York.
