Are U.S. Nuclear Reactors Adequately Protected Against Credible Terrorist Attacks? | LBJ School of Public Affairs | The University of Texas at Austin

AUSTIN, Texas – August 15, 2013 – The Nuclear Proliferation Prevention Project (NPPP) at The University of Texas at Austin's LBJ School of Public Affairs has released a report titled “Protecting U.S. Nuclear Facilities from Terrorist Attack: Re-assessing the Current ‘Design Basis Threat’ Approach."

Some key findings of the report include:

  • Some U.S. nuclear power plants are vulnerable to terrorist attack from the sea, but they are not required to protect against such ship-borne attacks.
  • Another serious terrorism danger is posed by three civilian research reactors that are fueled with bomb-grade uranium, which is vulnerable to theft to make nuclear weapons.  These facilities are not defended against a posited terrorist threat, unlike military facilities that hold the same material. 

Report co-author LBJ School Associate Professor Alan J. Kuperman, the coordinator of the Nuclear Proliferation Prevention Project, recently alerted nuclear security specialists to these dangers in a presentation at the annual meeting of the Institute of Nuclear Materials Management.  

Commenting on the new NPPP report, Prof. Kuperman said:  “More than 10 years have come and gone since the events of September 2001, and America’s civilian nuclear facilities remain unprotected against a terrorist attack of that scale.  Instead, our civilian reactors prepare only against a much smaller-scale attack, known as the “design basis threat,” while the government fails to provide supplementary protection against a realistic 9/11-type attack. It would be a tragedy if the United States had to look back after such an attack on a nuclear reactor and say that we could have and should have done more to prevent the catastrophe.”

The NPPP report also notes that some U.S. government nuclear facilities – operated by the Pentagon and Department of Energy – are protected against most or all of the above threats.  But other U.S. government nuclear sites remain unprotected against such credible threats.
