On May 11 and 13, 1998, India tested five nuclear weapons in the Rajasthan desert. By the end of the month, Pakistan had followed suit, claiming to have detonated six nuclear devices at an underground facility in the Chagai Hills. With these tests, the governments in Islamabad and New Delhi loudly announced to the world community, and especially to each other, that they both held the capability to retaliate with nuclear weapons in response to any attack.

What will be the strategic effects of these nuclear weapons developments? There are many scholars and defense analysts who argue that the spread of nuclear weapons to South Asia will significantly reduce, or even eliminate, the risk of future wars between India and Pakistan. These "proliferation optimists" argue that statesmen and soldiers in Islamabad and New Delhi know that a nuclear exchange in South Asia will create devastating damage and therefore will be deterred from starting any military conflict in which there is a serious possibility of escalation to the use of nuclear weapons. Other scholars and defense analysts, however, argue that nuclear weapons proliferation in India and Pakistan will increase the likelihood of crises, accidents, terrorism and nuclear war. These "proliferation pessimists" do not base their arguments on claims that Indian or Pakistani statesmen are irrational. Instead, these scholars start their analysis by noting that nuclear weapons are controlled by military organizations and civilian bureaucracies, not by states or by statesmen. Organization theory, not just deterrence theory, should therefore be used to understand the problem and predict the future of security in the region.

An updated Atoms for Peace program is needed to help solve problems of national and international security brought about by increased civilian use of nuclear energy.

Coherent and consistent leadership from the United States and other states is essential if the programs needed are to go forward with adequate speed.

The world's governance and enforcement machinery must be updated and strengthened if it is to be equal to the challenges.

Important leverage can be provided if the countries that have or readily could  have nuclear power can reach broad agreement that nuclear terrorism must be prevented. 

This paper discusses three questions:

1. Could terrorists or others steal nuclear fuel from research rectors, to make either a nuclear weapon or a "dirty bomb," a radiological dispersal device?
2. Could terrorists attack a research reactor with conventional explosives, for example with a truck loaded with such explosives, in order to disperse radioactivity from the fuel of the reactor to an area downwind of the reactor?
3. How do power reactors compare with research reactors as targets of terrorist attacks?

The answer to the first two questions is a qualified yes. In the comparison called for in the third question, the low-enriched uranium in power reactors is unsuitable for making nuclear weapons, without major reprocessing. However, the highly enriched uranium burned in many research reactors around the world is suitable for making nuclear weapons, if enough of it is available. Both power reactors and research reactors could be targets for terrorists trying to attack a reactor with a truck bomb, for the purpose of dispersing radioactive material, or trying to steal such material for the purpose of making a dirty bomb. The variations from reactor to reactor, in both attractiveness to terrorists and protection of the facility, are widespread.

This is a presentation made at the 2002 American Nuclear Society Winter Meeting in Washington, DC on November 19, 2002.

The presentation explores:

• Motivations for Past Terrorist Threats

• Motivation for New Terrorist Threats that are More Threatening
  

• Impact

• Threats Considered Feasible

New threats of terrorism are prompting the need for swift action to better secure nuclear material and strong radiation sources. Are measures already in place enough? The Stanford-Salzburg initiative suggests not.

This article analyzes the supply and demand sides in nuclear smuggling, as well as intermediaries between them, based on the 700 illicit trafficking incidents collected by the Stanford Database on Nuclear Smuggling, Theft, and Orphan Radiation Sources (DSTO) for the period 1991 to 2002. The supply side consists of people with access to nuclear and other radioactive material. It can be subdivided into civilian employees at source facilities, ranging from technicians to top managers; military personnel; and security guards. Intermediaries--traffickers and middlemen--can be categorized as amateurs, opportunist businessmen and firms, and organized crime groups. The demand side is represented by proliferating nation states, terrorist organizations, religious sects, separatist movements, and criminal groups or individuals interested in using nuclear and other radioactive material for malevolent purposes, such as murder, deliberate exposure, blackmail, and extortion.

International efforts to improve the security of nuclear material and facilities from theft and sabotage were intensified by the attacks of September 11. But the magnitude of the changes that are needed to protect against terrorist attacks like those of September 11 has not yet been widely appreciated, perhaps in part because of beliefs in some countries that what happened in the US on September 11 “can’t happen here.” This report will discuss the relevant features of the September 11 attacks, the recent illicit trafficking in nuclear and radioactive materials that might benefit terrorists, and the international efforts to improve physical protection after September 11.
