1938 – 2007
"It may take the unthinkable happening before the political process can screw up the courage to put an end to this ridiculously dangerous industry."
Paul L. Leventhal was a visionary who recognized the apocalyptic overlap between commercial nuclear power and nuclear weapons proliferation long before it was widely accepted. Before founding the Nuclear Control Institute (NCI) in 1981, he operated at the highest levels of the U.S. government to force accountability onto a dangerously unregulated industry.
As a senior staff member in the U.S. Senate, Paul was the architect of the 1974 law that shattered the U.S. Atomic Energy Commission, breaking it into independent regulatory and promotional agencies to eliminate its inherent conflict of interest. He spearheaded the investigation and legislation that became the U.S. Nuclear Non-Proliferation Act of 1978, establishing the modern framework for strict nuclear export controls. In 1979, he co-directed the Senate’s bipartisan investigation into the Three Mile Island meltdown, the most serious commercial reactor failure in U.S. history.
Refusing to accept the compromise that "Atoms for Peace" was safe from becoming "Atoms for War," Paul founded NCI to serve as an independent, relentless watchdog. For 22 years as President, he stood against immense corporate and governmental pressure to expose the sheer madness of a global plutonium economy.
NCI was routinely criticized by the nuclear industry as alarmist. Yet, history has vindicated Paul Leventhal and his institute time and time again. The warnings they issued decades ago are now recognized as foundational truths of global security.
The Warning: NCI argued that separating plutonium via reprocessing for commercial fuel (MOX) was an economic failure and a proliferation nightmare. Industry claimed it was the fuel of the future.
The Truth: Today, the commercial breeder reactor dream is dead. Almost all nations have abandoned reprocessing due to astronomical costs and unmanageable security liabilities, exactly as Paul predicted.
The Warning: NCI campaigned relentlessly to expose that over 150 civilian research reactors worldwide were running on Highly Enriched Uranium (bomb-grade material), creating a massive terrorism loophole.
The Truth: Through NCI's pressure on the RERTR program, the global phase-out of civilian HEU in favor of Low-Enriched Uranium (LEU) is now a universally accepted, primary objective of the IAEA and global security summits.
The Warning: In 1986, Paul convened the International Task Force on Prevention of Nuclear Terrorism, warning that reactors and transport ships were prime targets for catastrophic sabotage by non-state actors.
The Truth: Following the tragic events of September 11, 2001, the world woke up to the exact asymmetric threats NCI had spent 15 years mapping out, validating their campaigns to upgrade truck-bomb rules and operational safeguard responses.
The Warning: NCI uncovered a reckless plan to fly shipments of highly toxic plutonium from Europe to Japan via Alaska without crash-proof casks.
The Truth: By exposing this to the public and Congress, NCI successfully forced the cancellation of the flights, averting a potential global environmental catastrophe.
Paul did not fight this battle alone. He assembled a brilliant, dedicated team of theoretical physicists, researchers, and policy analysts at NCI who executed this watchdog mission with unmatched technical rigor and determination.
A theoretical physicist from Cornell University, Dr. Lyman provided the undeniable mathematical and scientific proof of the dangers of MOX fuel. His research definitively modeled the catastrophic cancer risks of severe accidents and exposed the gaping safety holes in the sea transport of high-level nuclear waste.
Joining NCI in 1991, Dolley was the institute's intelligence hub. He rigorously tracked global plutonium stockpiles, exposed vulnerabilities in international safeguard inspections, and authored critical reports tracking the illicit trafficking of Highly Enriched Uranium and Iraq's nuclear weapons program.
A vital architect of NCI's global reach, Tanzer organized international conferences across Europe, Latin America, and Japan. She co-edited seminal works on nuclear terrorism and arms control, ensuring NCI's technical warnings were translated into coordinated, international diplomatic pressure.
A fierce advocate who spearheaded grassroots and international campaigns. Clements led the charge against the Department of Energy's disastrous MOX fuel consortiums and fought on the front lines against the dangerous maritime shipments of plutonium from Europe to Asia.
A highly effective policy analyst who drove NCI's legislative strategies. Kuperman focused heavily on the U.S. program to eliminate the use of bomb-grade HEU in research reactors and co-authored the landmark 1987 report that successfully halted the airborne shipment of plutonium to Japan.
