A New Pathway To Enhance The Nuclear Security Regime, Francesca Giovannini 2016 American Academy of Arts and Sciences

A New Pathway To Enhance The Nuclear Security Regime, Francesca Giovannini

International Journal of Nuclear Security

The paper investigates the approach used by a new set of regional institutions, the Disaster Preparedness and Risk Management Organizations (DPRMOs), in strengthening regional governance and cooperation. It also inquires in what ways these new institutions might indirectly contribute to the establishment of a more cohesive global nuclear security framework. More specifically, through the examination of the case of Southeast Asia, the paper argues that these institutions, albeit without a specific and direct mandate to operate in the nuclear security domain, are fundamentally strengthening states’ capacity to assess risks and threats and to map vulnerabilities in timely fashion. They are ...


Modern Advancements In Post-Detonation Nuclear Forensic Analysis, S. Adam Stratz, Jonathan A. Gill, John D. Auxier II, Howard L. Hall 2016 University of Tennessee, Knoxville

Modern Advancements In Post-Detonation Nuclear Forensic Analysis, S. Adam Stratz, Jonathan A. Gill, John D. Auxier Ii, Howard L. Hall

International Journal of Nuclear Security

Deterring nuclear terrorism is a critical national asset to support the preclusion of non-state actors from initiating a nuclear attack on the United States. Successful attribution of a detonated nuclear weapon allows for timely responsive measures that prove essential in the period following a nuclear event. In conjunction with intelligence and law enforcement evidence, the technical nuclear forensics (TNF) post-detonation community supports this mission through the development and advancement of expertise to characterize weapon debris through a rapid, accurate, and detailed approach. Though the TNF field is young, numerous strides have been made in recent years toward a more robust ...


Evaluation Of Covert Plutonium Production From Unconventional Uranium Sources, Ondrej Chvala, Steven Skutnik, Tyrone Christopher Harris, Emily Anne Frame 2016 University of Tennessee

Evaluation Of Covert Plutonium Production From Unconventional Uranium Sources, Ondrej Chvala, Steven Skutnik, Tyrone Christopher Harris, Emily Anne Frame

International Journal of Nuclear Security

The potential for a relatively non-advanced nation to covertly acquire a significant quantity of weapons-grade plutonium using a gas-cooled, natural uranium-fueled reactor based on relatively primitive early published designed is evaluated in this article. The economic and technical issues that would influence the design decisions of a covert 239Pu production program are considered.

Several unconventional uranium acquisition approaches were explored. Methods for extracting uranium from enrichment tails, seawater, and coal ash sources were considered. The evaluation indicated that uranium extraction from coal ash or insitu leaching from underground deposits could be performed in economical manner that might be difficult ...

Modified Fault Tree Method For Vulnerability Analysis Of Nuclear Medicine Facility Security System Case Study: Radiotherapy Facility, Sardjito General Hospital, Haryono Budi Santosa 2016 Department of Nuclear Engineering and Engineering Physics, Universitas Gadjah Mada, Yogyakarta, Indonesia

Modified Fault Tree Method For Vulnerability Analysis Of Nuclear Medicine Facility Security System Case Study: Radiotherapy Facility, Sardjito General Hospital, Haryono Budi Santosa

International Journal of Nuclear Security

Assessing the vulnerability of physical protection systems (PPS) in nuclear medicine facilities is needed to prevent a security incident that could lead to the malicious use of nuclear material. Theft and sabotage of nuclear materials is becoming globally recognized. The current methods of assessing vulnerability tend to be oriented toward complex nuclear security; consequently, it is excessive to use such methods in simple facilities (i.e., radiotherapy facilities in hospitals).

The fault tree analysis is a method to assess vulnerability for a simple nuclear facility. The method’s primary events (i.e., basic events and undeveloped events) are able to ...


Opportunities And Challenges In Developing Nuclear Security In Africa, James Larkin Mfr 2016 The University of the Witwatersrand, Johannesburg

Opportunities And Challenges In Developing Nuclear Security In Africa, James Larkin Mfr

International Journal of Nuclear Security

Those involved in nuclear security recognize that regions of significant instability in Africa have an impact on the safety and security of the continent's nuclear material and un-enriched uranium; however, some countries outside of continental Africa have taken counterproductive approaches to this issue. Despite challenges, the nuclear security community continues to develop and apply appropriate levels of nuclear security where needed. The community also takes every opportunity to make significant contributions to the global discourse on nuclear security culture.


Nuclear Security Risk Analysis: An Insider-Outsider Collusion Scenario, Mohammad A. Hawila, Sunil S. Chirayath 2016 Nuclear Security Science & Policy Institute, Department of Nuclear Engineering Texas A&M University, College Station, TX-77843-3473, USA

Nuclear Security Risk Analysis: An Insider-Outsider Collusion Scenario, Mohammad A. Hawila, Sunil S. Chirayath

International Journal of Nuclear Security

This study analyses the vulnerability of the physical protection system (PPS) deployed at a hypothetical facility. The PPS is designed to prevent and eliminate threats to nuclear materials and facilities. The analysis considers possible outsider and insider threats. A modified adversary sequence diagram (ASD) evaluates threat pathways to test an insider-outsider collusion case. The ASD also measures the probability of adversary interruption by demonstrating the methodology for a typical nuclear facility.


Nuclear Security Culture And Batan’S Assessment: Batan’S Experience, Anhar R. Antariksawan 2016 National Nuclear Energy Agency of Indonesia (BATAN)

Nuclear Security Culture And Batan’S Assessment: Batan’S Experience, Anhar R. Antariksawan

International Journal of Nuclear Security

Organizations should increase safety to minimize the harmful effects of nuclear materials. Additionally, organizations should take measures to protect security culture within the organization itself. This paper covers the National Nuclear Energy Agency of Indonesia’s (BATAN’s) promotion of nuclear security culture and self- assessment projects, which is based on the International Atomic Energy Agency’s (IAEA) methodology.

Loss Of Identity, Radicalization, And Terrorism, Magdalena Martinez 2016 The University of San Francisco

Loss Of Identity, Radicalization, And Terrorism, Magdalena Martinez

Master's Theses

France and Belgium are two of the top countries in Europe with an increasing number of root fighters. Over the last two years, both countries have been primary targets of terrorism. This thesis investigates the repeated pattern of events and analyzes from a birds-eye view the cycle leading to the rise of terrorism in France and Belgium. This research disputes that anxiety causes discrimination and lack of integration in France and Belgium, which contributes an identity crisis. In essence, these factors trigger radicalization and lead to terrorism. Analyzing the patterns of terrorist activity and the path of radicalization is essential ...


The Identification And Prevention Of Insider Threats, Matthew D. Waters 2016 Eastern Kentucky University

The Identification And Prevention Of Insider Threats, Matthew D. Waters

Posters-at-the-Capitol

Insider threats, or attacks against a company from within, are a pressing issue both domestically and internationally. Frequencies of these threats increase each year adding to the overall importance of further research analysis. In fact, many case studies have been conducted which state that these employees who participate in insider attacks tend to exhibit certain personality and characteristic traits, as well as certain observable behaviors, that would indicate to other employees that an attack is imminent. It is hypothesized that companies will be able to take a more preventative stance of security as opposed to a reactive stance by identifying ...

UNLV Theses, Dissertations, Professional Papers, and Capstones

Designed as a three-article style dissertation, this study was developed to first assess literature and data related to veteran outcomes following active duty service. Secondly, this dissertation sought to determine the best approach for measuring changes in veteran outcomes as a function of the policy process, which resulted in the development of a new methodological approach, Event Outcome Analysis based on Event History Analysis. Finally, veteran outcomes in employment and educational degree attainment were measured using Event Outcome Analysis to determine the relative impact of the 2008 GI Bill on Post-9/11 veterans. Study findings included statistically significant 2008 GI ...


Complexity In Modern War: Examining Hybrid War And Future Us Security Challenges, Joseph Dvorak 2016 Missouri State University

Complexity In Modern War: Examining Hybrid War And Future Us Security Challenges, Joseph Dvorak

MSU Graduate Theses

Hybrid warfare is a recently formed concept that focuses on the complexity of modern conflicts and those in the future. After the Russian Federation annexed the Crimean Peninsula in 2014, US and Western analysts started using the term hybrid warfare to describe Moscow's strategy. Analysts and policymakers are starting to consider the approach and direction in Ukraine to be a new and unique type of warfare. This study discusses the usefulness of the term hybrid warfare and examines two case studies that reflect the characteristics of hybrid war, the conflicts in Syria and Ukraine, to determine if hybrid warfare ...


Frozen Conflicts, De Facto States, And Enduring Interests In The Russian Near Abroad, Brittany A. Pohl 2016 Missouri State University

Frozen Conflicts, De Facto States, And Enduring Interests In The Russian Near Abroad, Brittany A. Pohl

MSU Graduate Theses

The dissolution of the Soviet Union resulted in the establishment of fifteen sovereign nations and a number of separatist states concentrated in the greater Black Sea region. The latter, so-called de facto states, are the result of frozen conflicts that emerged as Moscow's grip over its territory weakened in the waning years of the USSR and dormant ethno-religious tensions erupted into internecine conflict. Separatists, ultimately with help from Moscow, were able to enshrine victories on the battlefield through ceasefires with metropolitan states that have held for over two decades. However, the issues surrounding these pseudo-states remain unsettled, and attempts ...
