[DRAFT: Hiroshima Report 2013] 3-(3) Efforts to Maintain and Improve the Highest Level of Nuclear Security

A) Minimization of HEU in Civilian Use

HEU has been utilized for civilian purposes through the use of research reactors and isotope production reactors. However, since HEU is suitable for the manufacture of nuclear explosive devices, if it is removed from a regulatory control without authorization, such as by theft, it becomes possible that non-state actors as well as states can produce nuclear explosive devices. Against this concern, the Global Threat Reduction Initiative (GTRI) was commenced in 2004 by the U.S. proposal for the purposes of returning Russian- or U.S.-origin HEU located in civilian sites in the world to its respective origins and converting research reactors to use low enriched uranium (LEU). The Nuclear Security Summits in 2010 and 2012 upheld this effort as one of the most important actions to be taken.

A) Accession Status to Nuclear Security Related Conventions

This report surveys the accession status of each country to the following nuclear security and safety related conventions: Convention on the Physical Protection of Nuclear Material (CPPNM), Amendment to CPPNM (CPPNM Amendment), International Convention for the Suppression of Acts of Nuclear Terrorism (Nuclear Terrorism Convention), Convention on Nuclear Safety (Nuclear Safety Convention), Convention on Early Notification of a Nuclear Accident, Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, and Convention on Assistance in the Case of Nuclear Accident or Radiological Emergency. The results are summarized in Table 3-4.

Nuclear security threat is defined as “a person or group of persons with motivation, intention and capability to commit criminal or intentional unauthorized acts involving or directed at nuclear material, other radioactive material, associated facilities or associated activities or other acts determined by the State to have an adverse impact on nuclear security.”[1] The IAEA recommends to take a graded approach that takes into account: “the current evaluation of the threat, the relative ‘attractiveness’[2], the nature of the nuclear material and potential consequences associated with the unauthorized removal of nuclear material and with the sabotage against nuclear material or nuclear facilities”[3] to decide physical protection requirements. This suggests that the more suitable nuclear and other radioactive material, related nuclear facilities and activities are to achieving certain malicious intentions, the higher the nuclear security risk is, thereby requiring a high-level of protection measures corresponding to the security risk. In a similar way, the larger the consequences of a certain malicious act, the stronger the level of security measures required.

In response to the increasing concern about “loose nukes” resulting from the dissolution of the Soviet Union and the terrorist attacks on the United States in September 2011, international efforts to enhance nuclear security have accelerated and nuclear security tools have been greatly reinforced (augmented). In 2005, the Amendment to the Convention on the Physical Protection of Nuclear Material was adopted (has not yet entered into force). In 2007, the International Convention for the Suppression of Acts of Nuclear Terrorism (Nuclear Terrorism Convention) entered into force. In 2011, the fifth revision of Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities (INFCIRC/225/Revision 5) was issued. In addition, the two Nuclear Security Summits in 2010 and 2012 provided opportunities for world leaders to show commitment to strengthening nuclear security by declaring and supporting nuclear security approaches to be taken. Similarly, the International Conference on Nuclear Security: Enhancing Global Efforts, organized by the International Atomic Energy Agency (IAEA) in July 2013, served as a platform for participating countries to make official remarks about their respective nuclear security policies at the Ministerial Meeting at the beginning of the conference. These official statements, as well as the membership status of international conventions and implementation status of the measures recommended to take by INFCIRC/225/Rev.5, provide an important overview for assessing the nuclear security performance of each country.
