Overview Of The United States Withdrawal From The Intermediate-Range Nuclear Forces Treaty, William Steinberger
Overview Of The United States Withdrawal From The Intermediate-Range Nuclear Forces Treaty, William Steinberger
Purdue Workshop on Nonproliferation: Technology and Approaches
The Intermediate-Range Nuclear Forces (INF) Treaty symbolized the end of the Cold War and the likely termination of thistreaty marks the beginning of a new era. On February 1, 2019, Secretary of State Pompeo announced that the United States(U.S.) would withdrawal from the INF Treaty citing repeated violations by the Russian Federation as cause for withdrawal. Asearly as 2008, U.S. intelligence agencies reported missile testing by the Russian Federation of a cruise missile system that couldhave a range between the limits outlined by the INF Treaty. The Russian Federation has repeatedly denied the allegations andhas suggested that the U.S. is …

To support the mission of the Countering Weapons of Mass Destruction Office of the Department of Homeland Security, the Detection for Nuclear Nonproliferation group is researching active interrogation techniques and the development of new detection algorithms for fast neutron spectroscopy. The Countering Weapons of Mass Destruction Officehas loaned us a Varian M9 linear accelerator (linac), helium-3 detectors, boron-coated straw detectors, and perfluorocarbondetectors as part of this research, providing a variety of tools to conduct our experiments.In the summer of 2018, a thorough licensing process concluded, and preliminary experiments commenced. Later in the year, the facility was approved to possess and …

Purdue Workshop on Nonproliferation: Technology and Approaches
Design a small modular reactor that is easily transportable for use in disaster relief as well as remote military outposts. A rail shippable reactor gives quick and easy transportation from one part of a country to another. The reactor must have a three MWe production capacity to ensure the reactor has the performance to power larger government facilities, such as hospitals and water treatment plants. The reactor must have enough fuel for a six-month minimum fuel cycle. Atmospheric cooling only provides the ability to reject heat to the atmosphere, minimizing the weight requirements. Uranium fuel will have a maximum of …
Regulatory Design For Transport Security Regulations Of Nuclear And Other Radioactive Material, Marc R. Fialkoff
Regulatory Design For Transport Security Regulations Of Nuclear And Other Radioactive Material, Marc R. Fialkoff
Purdue Workshop on Nonproliferation: Technology and Approaches
A cornerstone within a nuclear security regime of a country is a legislative and regulatory framework that both regulates the individuals using radioactive and nuclear materials, but also regulates the regulators for their commitments under International Law. When drafting nuclear law and regulations, both technical and legal expertise is needed to ensure the regulation meets the technical requirements for security, but also is legally enforceable within a country’s jurisdiction. While the Primary Nuclear Law, or Enabling Act provides establishes the Competent Authority and responsibilities for nuclear security, regulatory development is where the proverbial, rubber meets the road for requirements. The …
The Effects Of The Urban Environment On Background Neutron Flux, Eric Reddick, John Burkhardt, Marshall Millett
The Effects Of The Urban Environment On Background Neutron Flux, Eric Reddick, John Burkhardt, Marshall Millett
Purdue Workshop on Nonproliferation: Technology and Approaches
This project will measure the neutron background inan urban environment using United States Naval Academy’s(USNAs)high sensitivity neutron detection system, called the Large Neutron Sensor (LNS).The background neutron flux represents noise and affects our ability to identify a signal from illicit source material, including plutonium.As the neutron background essentially rains down from high energy cosmic ray events in our upper atmosphere, the shielding effect of skyscrapers in an urban environment on the ground level background is of interest.Witha characterization of the neutron background in this environment, end users will be able to optimize the effectiveness of survey protocols and alarm algorithms.

Purdue Workshop on Nonproliferation: Technology and Approaches
One major problem with nuclear security measurements involves source identification inthe presence of low signal-to-background ratio. This scenario iscommon to several applications, ranging from radiation identification atportal monitors to radiation source search with unmanned vehicles. In this context of identification of a large variety of sources, including natural and medical sources, sensitive sources of particular interest, but also potentially new/unknown sources for which no reference measurement is available, statistical methods are particularly appealing for their ability to capture the random nature of the measurements. Among them, Bayesian methods form a generic framework allowing for uncertainty quantification and propagation, which is …
Radiation Detection, Measurement, And Visualization Assisted By Virtual And Augmented Reality, Erik Medhurst, Rizwan Uddin
Radiation Detection, Measurement, And Visualization Assisted By Virtual And Augmented Reality, Erik Medhurst, Rizwan Uddin
Purdue Workshop on Nonproliferation: Technology and Approaches
Localizing a radiation source in an urban environment is a challenge in nuclear nonproliferation and radiation detection. Mobile radiation sensor networks can be sent into an area of interest to collect count rate measurements at many locations in an attempt to find the radiation source. However, there are numerous factors that cause fluctuations in background count rate such as time and location, and these factors make it challengingto analyze thecollected data. Displaying these measurements in a virtual model has contextualized them and made it easier to determine if environmental factors are introducing false positives. A virtual model has been shown …
Exploring Laser Induced Breakdown Spectroscopy (Libs) For Post-Detonation Nuclear Forensics Debris Analysis, Justin Knoll, Chad Schools, David Fobar
Exploring Laser Induced Breakdown Spectroscopy (Libs) For Post-Detonation Nuclear Forensics Debris Analysis, Justin Knoll, Chad Schools, David Fobar
Purdue Workshop on Nonproliferation: Technology and Approaches
In the unlikely but catastrophic event of a nuclear terrorist attack our government leadership will need reliable information to rapidly inform critical decisions. This research explores the use of Laser Induced Breakdown Spectroscopy (LIBS) as a potential analysis tool in the National Technical Nuclear Forensics process. The current state of post detonation nuclear forensics requires ground and air samples be collected and shipped to state-of-the-art laboratories for radiochemical analysis. The samples undergo many measurements and useable data is produced as these measurements are completed. This data flows back into the process to guide additional measurements and inform the process of …

Analysis of Proliferation Resistance of Small Modular Reactors (SMR) for the Expansion of Civilian Nuclear Power Systems A. S. Mollah Department of Nuclear Science and Engineering Military Institute of Science and Technology Mirpur Cantonment, Dhaka-1216, Bangladesh Abstract Nuclear energy has the potential benefit to make an important contribution for mitigating greenhouse gas (GHG) emissions that cause climate change. Expanding nuclear energy capacity worldwide based on large centralized facilities poses many challenges and risks due to the large capital costs, important safety issues, obstructive public attitude, and persistent concerns about proliferation-that is, the intentional misuse of nuclear technology and material. SMRs, …
A Characterization Of Undersea Neutron And Capture Gamma Signatures Resulting From Special Nuclear Material On A Maritime Vessel, Elizabeth Troy
A Characterization Of Undersea Neutron And Capture Gamma Signatures Resulting From Special Nuclear Material On A Maritime Vessel, Elizabeth Troy
Purdue Workshop on Nonproliferation: Technology and Approaches
Special Nuclear Materials (SNM) located aboard ships emit radiation that may be detectable in the undersea environment. An Unmanned Underwater Vehicle (UUV) could be equipped with detection capabilities to determine whether commercial or private vessels are carrying SNM prior to reaching port. Additional research is needed improve such a UUV’s ability to detect and discriminate between types of SNM and reduce false- positive detections. This research builds on past work by C. T. McKay to provide a higher fidelity characterization of detectable radiation signatures from SNM in the undersea environment with a focus on plutonium-bearing SNM. 252Cf will be used …
