Nuclear Power: Black Sky Liability Or Black Sky Asset?, Sherrell R. Greene
Nuclear Power: Black Sky Liability Or Black Sky Asset?, Sherrell R. Greene
International Journal of Nuclear Security
Ready access to abundant electricity is a key enabler of modern life. During the past decade the vulnerability of Critical Infrastructure sectors in the U.S. to a variety of natural hazards and man-made threats has become increasingly apparent. The electrical infrastructure (the “Grid”) is the foundation for all other critical civil infrastructures upon which our society depends. Therefore, protection of the Grid is an energy security, homeland security, and national security issue of highest importance. Geomagnetic disturbances (GMD) induced by solar coronal mass ejections (CMEs), electromagnetic pulse (EMP) attacks, and cyber attacks are three events having the potential to plunge …

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
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
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 accommodate fault causes …

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.
Opportunities And Challenges In Developing Nuclear Security In Africa, James Larkin Mfr
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
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.
Experimental Methods In Cryogenic Spectroscopy: Stark Effect Measurements In Substituted Myoglobin, Bradley Michael Moran
Experimental Methods In Cryogenic Spectroscopy: Stark Effect Measurements In Substituted Myoglobin, Bradley Michael Moran
Theses and Dissertations
Dawning from well-defined tertiary structure, the active regions of enzymatic proteins exist as specifically tailored electrostatic microenvironments capable of facilitating chemical interaction. The specific influence these charge distributions have on ligand binding dynamics, and their impact on specificity, reactivity, and biological functionality, have yet to be fully understood. A quantitative determination of these intrinsic fields would offer insight towards the mechanistic aspects of protein functionality. This work seeks to investigate the internal molecular electric fields that are present at the oxygen binding site of myoglobin.
Experiments are performed at 1 K on samples located within a glassy matrix, using the …

Promoting Excellence And Demonstrated Competence For Nuclear Security Training, Daniel Johnson, Brunelle Battistella, Roger Howsley
International Journal of Nuclear Security
The international community has spent considerable time, money, and effort attempting to establish a series of national and regional Centres of Excellence (COEs), also known as Nuclear Security Training and Support Centres (NSSCs). These Centres tend to have a wide variety of objectives, structures, and methods of delivery. Unsurprisingly, no internationally accepted standard exists on how they should operate. The IAEA has produced some excellent guidance (TECDOC 1734), but by virtue of its role cannot provide standards for benchmarking success. Against this backdrop, the World Institute for Nuclear Security (WINS) launched the WINS Academy, an initiative to provide practitioners with …
