Nuclear Forensics and What it Can Tell Us about Materials from the Front End of the Uranium Fuel Cycle
Dr. Naomi Marks
October 29th, 2018 4:00 – 5:00 PST pm in Etcheverry Hall 3105, UC Berkeley
The illicit trafficking of radioactive and nuclear materials has been the subject of increasing concern in the international community over the past decade. These materials are problematic because of their radiotoxicity, and have been lately discovered in settings ranging from contaminated scrap metal to Am-241-laced gambling dice. The trafficking of nuclear materials poses a greater concern, as these materials pose a proliferation risk if they are diverted and escape regulatory control. Nuclear forensic signatures can help to elucidate the origin of a material, and are also relevant for assessing the consistency of a state’s declarations. In this talk I will describe case studies and research on elemental and isotopic signatures that can be used to address questions of nuclear forensic interest.
Naomi Marks is a researcher in nuclear forensics at Lawrence Livermore National Laboratory (LLNL) with expertise in thermal ionization mass spectrometry and electron probe microanalysis, including applications to nuclear forensics; as well as expertise in U mining and milling; isotopic and chemical evolution of early solar system materials; and international nuclear forensics engagements. She is serves as developer and designer for the NNSA and IAEA Nuclear Forensics training courses and has traveled to more than a dozen countries in support of nuclear forensics cooperation engagements. Naomi’s current research focuses on identifying geochemical signatures in materials from the early part of the uranium fuel cycle and on developing nuclear forensics libraries.
Plutonium Contamination of the Environment: What’s the Problem?
Dr. Mavrik Zavarin
April 24th, 2018 12:00 – 1:00 pm in Etcheverry Hall 4101, UC Berkeley
Over the past 75 years, the global inventory of plutonium on earth has increased by a factor of approximately 10 6 . A fraction of this plutonium inventory has been released into the environment and can be identified in sediments, rock and glacial ice. As a result, plutonium environmental chemistry has gained sincere interest both in the public and scientific communities. Plutonium aquatic chemistry, mineral/water interface reactions, interaction with microbes, as well as its association with particles have been studied to quantify plutonium mobility in and risk to the environment. In this presentation, we will review the major plutonium contamination events, discuss what we have learned regarding its longterm fate in our environment, and provide examples of site remediation and monitoring efforts.
Dr. Mavrik Zavarin received his BS in chemistry (1993) and PhD in Soil Chemistry (1998) from the University of California at Berkeley. Dr. Zavarin has spent much of his career at Lawrence Livermore National Laboratory (LLNL) studying actinide
environmental chemistry. He is presently the Director of the Glenn T. Seaborg Institute.

It serves as a national center for the education and training of undergraduate and graduate students, postdocs and faculty in transactinium science. Dr. Zavarin holds adjunct appointments at Las Positas Community College and Clemson University.
The Implications of the Trump Nuclear Posture Review
Ambassador Linton F. Brooks
March 19, 2018 4:00 – 5:00 pm
Etcheverry Hall 3113, UC Berkeley
Like each of its post-Cold War predecessors, the Trump administration has reviewed its policies and posture with respect to nuclear weapons. The result is a mixture of continuity and change, with the change reflecting a re-focus from the long-range hopeful vision of the early Obama administration to a more somber assessment of near-term threats.
This presentation will discuss what is new in the document, the significance of the changes and the additional policy and technical
challenges resulting from the international developments to which the administration is responding. It will focus on the areas that have been most contentious and examine the validity of the concerns raised.
Ambassador Brooks served from July 2002 to January 2007 as Administrator of the U.S. Department of Energy’s National Nuclear Security Administration, responsible for the U.S. nuclear weapons program and for the Department of Energy’s international nuclear nonproliferation programs. In the early 1990s, he served as Chief U.S. Negotiator for the first Strategic Arms Reduction Treaty. Ambassador Brooks has over five decades of experience in national security, much of it associated with nuclear weapons, including service as Assistant Director of the Arms Control and Disarmament Agency, Director of Defense Programs and Arms Control on the National Security Council staff and a number of Navy and Defense Department assignments. As a Navy submarine officer, he served on four nuclear-weapons capable ships. Ambassador Brooks is now an independent consultant on national security, a Senior Advisor at the Center for Strategic and International Studies, a Distinguished Research Fellow at the National Defense University, a member of the National Academy of Sciences Committee on International Security and Arms Control and of the Board of Managers supervising Sandia National Laboratories the State Department International Security Advisory Board and an advisor to five other Department of Energy national laboratories.

Dealing with Secrecy, Trust and Access in Nuclear Weapons Verification
February 14, 2018 at 1:00 pm – 2:00 pm
Future nuclear arms-control agreements could place numerical limits on the total number of warheads in the arsenals of the weapon states. Verifying these agreements would face at least two fundamentally new challenges. First, inspectors would have to confirm that the number of declared items does not exceed the agreed limit; and, second, inspectors would also have to confirm the authenticity of nuclear warheads prior to dismantlement. Both tasks may involve procedures that put at risk classified or otherwise sensitive information and require access to sensitive facilities. A viable verification regime needs to protect this information and possibly limit access to these facilities while providing inspectors the ability to acquire data they can trust. This presentation reviews the emerging challenges for nuclear verification and proposes technical approaches to address them building on new applications of cryptography and information security.
Sébastien Philippe is a doctoral candidate in applied physics at Princeton University’s Department of Mechanical and Aerospace Engineering. His research focuses on innovative verification approaches and technologies to support future international treaties, with a focus on nuclear non-proliferation, arms control and disarmament.

Nondestructive Assay for International Safeguards
Dr. Alexis Trahan, LANL
October 23rd, 2017
From the Atoms for Peace speech in 1953 to the JCPOA (Iran Deal) in 2015, nuclear nonproliferation has been crucial to maintaining peace throughout the world. International Safeguards is the system of inspection and verification that the International Atomic Energy Agency (IAEA) uses to maintain that peace and prevent weapon proliferation. We will discuss safeguards and how it fits into the IAEA’s mission, with an emphasis on special nuclear material nondestructive assay (NDA) methods. The science of NDA will be discussed followed by an overview of selected technologies employed by the IAEA. Finally, we will go over NDA of spent nuclear fuel, discussing currently employed techniques and research in the area taking place at LANL.

Potential of Cognitive Computing for National Security Missions
Dr. David R. Farley, SNL
September 25th, 2017
There has been substantial progress in machine learning, cognitive computing and other data analytics flavors. Decision makers, nuclear power plant operators, intelligence analysts and other high-consequence industries seek to understand the potential impact of these new computer-enhanced analytic tools. IBM’s Watson cognitive computing platform enables users to ask natural language questions and evaluate hypotheses along with supporting evidence in the form of specific passages from a vast corpus of changing knowledge. Watson currently supports evidence discovery for agencies in the Federal Government and has made significant strides in various industries, such as indications analysis for diagnosing diseases in the healthcare industry. But do platforms like Watson deliver for national security missions, and how do we assess this? In this presentation, an overview of the national lab work on using Watson is detailed, as well as potential paths forward.

Improving beta-decay studies for fundamental science and applications
Dr. Nicholas Scielzo
April 13th, 2017
Recent advances in radioactive-ion beams and ion-trapping techniques are opening up new opportunities for improved studies of the neutrinos and neutrons emitted in nuclear beta decay. A novel ion-trap system has been developed to address fundamental questions ranging from electroweak theory to the origin of the elements and to provide nuclear data for nuclear-energy and stockpile-stewardship applications. When a radioactive ion decays in the trap, the recoil-daughter nucleus and emitted particles emerge from the trap volume with negligible scattering and propagate unobstructed through vacuum. This allows the momentum and energy of particles that would otherwise be difficult (or even impossible) to detect to be reconstructed from the momentum imparted to the recoiling nucleus. Beta-delayed neutron spectroscopy can be performed by circumventing the difficulties associated with direct neutron detection and instead reconstructing the neutron emission probabilities and energy spectra from the time of flight of the recoiling nuclei. In addition, a determination of the direction and energy of each emitted neutrino in the decays of 8Li and 8B has been performed to search for new particles and interactions. Recent results from decay studies using the Beta-decay Paul Trap (BPT) at Argonne National Laboratory will be presented and future prospects for these approaches will be discussed.
Dr. Nicholas Scielzo is currently a Deputy Group Leader for the Nuclear Particle Physics Group within the Nuclear and Chemical Sciences Division at LLNL. He earned a BA in chemistry and physics from Harvard University in 1997 and a PhD in physics from the University of California at Berkeley in 2003. He arrived at LLNL in 2006 as a Lawrence Fellow after spending 3 years at Argonne National Laboratory developing novel techniques to test the Standard Model of particle physics using short-lived radioactive nuclei. At LLNL, he has established a multi-faceted beta-decay spectroscopy program that uses ion traps, radioactive beams, and an assortment of specialized radiation detectors to perform neutrino and neutron spectroscopy to test the electroweak interaction, improve our understanding of heavy-element nucleosynthesis, and provide high-quality nuclear data for stockpile-stewardship and reactor-modeling applications. He has also developed new techniques to search for neutrinoless double-beta decay and to determine reaction cross sections on radioactive isotopes. In the last several years he has served as the primary advisor for 4 graduate students who received their PhD from the University of California at Berkeley.
Spatially Resolved Uranium Speciation in Nuclear Materials by Scanning Transmission X-ray Microscopy
Dr. David Shuh
February 28th, 2017
The production and manipulation of nuclear material can leave distinct physical and chemical signatures, which can later be characterized to provide evidence of the origin and process history of an unidentified specimen, a field known as ‘nuclear forensics’. A broad variety of analytical chemistry techniques can provide information about interdicted and post-detonation materials. Here, we present the results of several research studies of uranium-bearing forensic specimens by soft X-ray scanning transmission X-ray microscopy (STXM). STXM yields X-ray absorption spectroscopy data with 25-nm or better spatial resolution, making it possible to quantitatively evaluate variations in oxidation state and other chemical properties across a heterogeneous specimen. Operating in the soft X-ray regime provides access to the NIV,V edges of the actinides and the oxygen K edge, which is highly sensitive to variations in U-O bonding, and consequently carries unique fingerprints of uranium oxides and their hydrates. Thus, this approach makes it possible to evaluate the oxidation state and the heterogeneity of nuclear forensic samples, yielding information on formation or process history, and/or past storage conditions. In studies of U-bearing glassy materials, the L edges of some transition metals (particularly iron, which influences the redox behavior of uranium) can provide additional insights. Technical developments in STXM operations relevant to forensics are also summarized. In particular, we report on improvements in sample preparation and rapid data analysis methods implemented in STXM experiments at Beamline 11.0.2 of the Advanced Light Source. LLNL-ABS-690941

Compact quasi-monoenergetic photon applications and sources for nuclear applications
Dr. Cameron Geddes
January 24, 2017
Near-monoenergetic photon sources at MeV energies offer improved sensitivity at reduced dose for nuclear nonproliferation and related applications. Assessments of application-specific benefit from mono energetic photons will be described, including for cargo screening, active interrogation, treaty verification, nondestructive assay, and emergency response. Thomson (also referred to as Compton) scattering sources are an established method to produce appropriate photon beams. Applications are however restricted by the size of the required high-energy electron accelerator, scattering (photon production) system, and shielding for disposal of the high-energy electron beam. Laser-plasma accelerators (LPAs) produce GeV electron beams in centimeters, using the plasma wave driven by the radiation pressure of an intense laser. Designs, and development of an experimental facility to demonstrate a compact photon source using such accelerators will be described, together with the path to a application-relevant photon source system.
Dr. Geddes is a staff scientist in the BELLA center of Lawrence Berkeley National Laboratory, investigating use of laser driven plasma waves to build compact next generation particle accelerators and photon sources. These accelerators sustain much higher accelerating fields than conventional devices, allowing compact machines. His current project is developing compact sources of near-monochromatic MeV photons for nuclear material detection and characterization
Cryogenic Gamma-ray detectors with Ultra-High Energy Resolution
December 1, 2016
Magnetic microcalorimeter (MMCs) gamma-ray detectors with operating temperatures below 50 mK offer an order of magnitude higher energy resolution than semiconducting Ge and Si detectors. They are based on measuring the change in magnetization after gamma absorption increases the detector temperature. MMCs can have an energy resolution <50 eV at 60 keV, and therefore detect isotopes whose gamma emissions are obscured by line overlap in conventional Ge detectors. The high energy resolution can greatly improve the accuracy of non-destructive analysis of nuclear materials, both in fundamental science and nuclear safeguards applications. We are currently developing arrays of MMC detectors to increase the detector sensitivity. We are also building refrigerators to make operating temperatures of 15 mK accessible fully automated and without the use of cryogenic liquids. This talk discusses the design and performance of MMC gamma detectors at LLNL, and outlines experiments that can serve as thesis project for graduate students who are interested in ultra-high resolution detector development.
Stephan Friedrich received his Ph.D. in Applied Physics from Yale University in 1997 with a dissertation on superconducting tunnel junction X-ray detectors for high-energy astrophysics. He then adapted these detectors for operation at the ALS synchrotron at the Lawrence Berkeley National Lab for biophysics and material science experiments. Since 2002, Dr. Friedrich has led the cryogenic detector group at Lawrence Livermore National Lab, developing ultra-high resolution X-ray and gamma-ray detectors for basic science and national security applications. He has supervised several graduate students who have written their theses on cryogenic detector development and the experiments they enable.
