Nuclear Arms Control

Subject The US arms control agenda. Significance Despite having less than a year in office, President Barack Obama's administration is sustaining a high-profile arms control agenda in 2016. The administration wants to restore several damaged treaties with Russia, broaden Russia-China-US cooperation on various non-proliferation issues and leave Obama's successor a firm nuclear security architecture. Arms control is a consultative, long-term diplomatic process, and is susceptible to the political imperatives of more immediate regional crises. Impacts Tacit US support of Israeli nuclear opacity will undermine arms control efforts in the Middle East. Post-Obama arms control efforts are likely to focus on the security of nuclear material, rather than strategic arms reductions. Senate retirements will undermine US arms control advocacy in Congress. The United States will retain its nuclear arsenal indefinitely despite criticism from its allies.

AbstractThe forthcoming arrival of small modular reactors and other advanced nuclear reactor technologies can be an immensely beneficial development in the world’s collective pursuit of energy security and meeting climate change objectives. The key question is whether or not these new reactor technologies significantly alter the fundamental premises underlying the existing nuclear security legal regime. The Convention on the Physical Protection of Nuclear Material and its Amendment (A/CPPNM) are the only legally binding international instruments governing the physical protection of nuclear materials and nuclear facilities. Together the A/CPPNM and the international guidance on nuclear security comprise the current legal framework for nuclear security. This chapter examines whether the A/CPPNM adequately covers advanced reactor technologies; and whether the States that are interested in acquiring these new reactor technologies have the capacity to effectively implement the associated legal requirements, regulatory standards, and international guidance that comes along with such technologies. The analysis touches upon the role of the International Atomic Energy Agency (IAEA), the IAEA Nuclear Security Guidance, and issues of cybersecurity.

The CLYC (Cs[Formula: see text]LiYCl[Formula: see text]:Ce) detector is a scintillator detector sensitive to both neutron and gamma radiation and capable of separating the two types of radiation by pulse-shape discrimination. This feature is interesting as pertains to the development of non-destructive assays for the safeguard of nuclear material, nuclear security, and fast-neutron personal dosimetry. A [Formula: see text] CLYC detector highly enriched with [Formula: see text]Li was purchased and tested with analog and digital electronics. In this work, we report on the characterization of the detector in terms of linearity, energy resolution, and full-energy efficiency for gamma rays. This characterization was achieved by measurements with calibrated gamma-ray point-sources with an analog measuring chain, in a well-defined, reproducible geometry. The experimental data were also used to validate a model of the detection system that was developed with the Monte Carlo code MCNP-CP. This work is part of a collaborative agreement between SCK•CEN and JRC-Geel.

ABSTRACT Recent nuclear forensics cases have focused primarily on plutonium (Pu) and uranium (U) materials. By definition however, nuclear forensics can apply to any diverted nuclear material. This includes neptunium (Np), an internationally safeguarded material like Pu and U, that could offer a nuclear security concern if significant quantities were found outside of regulatory control. This case study couples scanning electron microscopy (SEM) with quantitative analysis using newly developed specialized software, to evaluate a non-traditional nuclear forensic sample of Np. The results of the morphological analyses were compared with another Np sample of known pedigree, as well as other traditional actinide materials in order to determine potential processing and point-of-origin.

Illicit Trafficking

The nuclear security architecture in India is three-fold: the infrastructure security including physical security of the nuclear plant; port and border security including training and capacity building to prevent any illicit trafficking of nuclear material into the country and; the inter-institutional coordination at the Centre and State level during radiological emergencies. However, there exist structural weaknesses that need to be accounted for in all these three areas. It is imperative to develop capacities not only for safe handling, transport and disposal of nuclear material but also instituting stringent cyber-security laws, border security measures and functional Centre-State coordination in crisis situation for the safety and security of the general population. The following paper seeks to address these challenges and provide recommendations for strengthening the nuclear security and disaster response framework in India. The paper draws recommendations from the 2019 IPCS workshop on Smuggling and Radiation Detection, on the illicit trafficking of radioactive materials supported by the Office of Nuclear Smuggling Detection and Deterrence (NSDD) of the United States Department of Energy (DOE).

Long Time

Radioactive and nuclear materials have been used for a long time in warfare. During the 20th and 21st centuries, a large number of atmospheric and underground nuclear weapons tests were carried out, even after the Non-Proliferation of Nuclear Weapons Treaty (NPT), leading to ecologically and socially destroyed sites. The most recent ones were in North Korea and Russia. With the widespread of peaceful use of radiological and nuclear material, the threats of nuclear terrorism or malicious use of these materials have become major concern across the world. Although the issuing of the Physical Protection of Nuclear Material treaty in 1997 (CPPNM), a considerable number of incidents involving radioactive materials due to unauthorized access or use were reported to the Incident and Trafficking Database (ITDB) system of the International Atomic Energy Agency (IAEA). In Lebanon, radioactive materials are vastly used in medicine, industry, research and agriculture. As a consequence, our country is facing the world common concerns and threats, especially after recent security status and geopolitical situation in the region. This work served to evaluate the current national situation relevant to nuclear security, where strong and weak points, pertinent to legal texts and procedures, were highlighted in order to deduce essential recommendations that could help in strengthening national security regime. The exerted governmental efforts were presented and discussed.
