DATE/TIME:
MON, 10/9/2023 - 3:00PM TO 4:00PM
LOCATION:
3105 ETCHEVERRY HALL

Abstract

This talk will focus on the intersection between policies to decarbonize our energy system and efforts to ensure a just transition for fossil-fuel workers and dependent communities. One opportunity that has emerged is the potential to repower retiring coal power plants with small, modular nuclear reactors. Such projects could leverage existing infrastructure and workforce. I will explore some of first coal-to-nuclear projects underway, along with state and federal policies to aid such efforts.

Next-generation neutrino detection with Eos

SPEAKER:

Professor Gabriel O. Gann

Associate Professor of Physics, UC Berkeley

Faculty Scientist, LBNL

DATE/TIME:

Abstract

Neutrinos are some of the most fascinating particles that occur in nature. Over one billion times lighter than the proton, the neutrino was once thought to be massless and to travel at the speed of light. This talk will discuss the ways in which neutrinos can offer insights into the world around us, and present recent technological advances that enable a new kind of “hybrid" neutrino experiment, which would combine two highly successful detection techniques: the topological information of Cherenkov detectors, with the high light yield of scintillators. A technical demonstrator for this technology is currently being deployed in the Nuclear Engineering department, and the status and plans for this project will be presented.

Bio

Prof. Orebi Gann joined the UC Berkeley Physics department faculty in January 2012, with a joint appointment in the Nuclear Science Division at LBNL. She completed her postdoctoral research at University of Pennsylvania from 2008-2011, having graduated with a DPhil from University of Oxford in 2008. Prof. Orebi Gann leads the proto-collaboration pursuing Theia, a large-scale realization of the technology being tested in Eos.

Karl van Bibber Group Awarded 5-Year U.S. Department of Energy Grant

NDR03762-positive-Edit

The group of professor Karl van Bibber has been awarded a $1.1M grant for five years from the Department of Energy, for the proposal "Innovative metamaterials and quantum amplifiers for very high mass dark matter axion searches".  This work supports research and development of novel microwave resonators of metallic or dielectric microstructures whose plasma frequency can be engineered and tuned. The development of such devices would open up the possibility of experiments searching for the dark matter of the universe in the form of a very light hypothetical particle, the axion which can resonantly convert to a weak radio signal in a strong magnetic field. Berkeley's partners in the proposal, a group at the University of Colorado led by Konrad Lehnert will also receive $1.1M for R&D on innovative quantum amplifiers and quantum acceleration schemes at very high frequencies.

Kaleidos: Making Nuclear Power Portable at Radiant Nuclear

SPEAKER:

Dr. Benjamin R. Betzler

Head of Nuclear Engineering at Radiant

DATE/TIME:

LOCATION:
3105 ETCHEVERRY HALL

Abstract

Increased industry development of nuclear microreactors over the last several years is largely due to their portability and operational flexibility, making them a feasible carbon-free technology for a variety of electrical grid sizes and remote locations. Reliability and operational flexibility, with years of operation without refueling, are some of the unique microreactor characteristics. These are designed characteristics of Radiant Nuclear’s Kaleidos, a 3.5 MWt portable nuclear microreactor intended to replace diesel generators and to provide power in remote or emergency deployment scenarios. Radiant is pursuing a fueled demonstration of this microreactor at the National Reactor Innovation Center Experimental Breeder Reactor (EBR)-II Test Bed [3] at Idaho National Laboratory in 2026.

Bio

Dr. Benjamin R. Betzler heads a team of nuclear engineers to design and analyze a portable nuclear microreactor. He joined Radiant after over 8 years as a research staff member at Oak Ridge National Laboratory, which followed the completion of his Ph.D. in nuclear engineering and radiological sciences at the University of Michigan. His expertise is in advanced reactor design and Monte Carlo radiation transport methods.

Radioactive Mice! How We Use the Mouse Model to Study Radiotherapeutics and Decontamination at LBNL

Alexia Cosby, Ph.D.

DATE/TIME:

LOCATION:
3105 ETCHEVERRY HALL

Abstract

The mouse model is an essential component for validating preclinical research. Here at LBNL, we use the mouse model to investigate two distinct challenges: 1) designing and evaluating radiotheranostics, and 2) understanding radiocontamination in the event of a nuclear disaster.Radiotheranostics for cancer diagnosis is a dynamic approach to dually diagnose and treat malignancies with a pair of tandem radioisotopes. An alternative approach to a targeting system is herein explored through the development of siderocalin-Trastuzumab fusion proteins, where the Scn protein is fused with HER2+ targeting antibody trastuzumab. We demonstrate the efficacy of the tetravalent theranostic metal pair 227 Th (therapy, α, t 1/2 =10 d) and 89 Zr (imaging, β +, t 1/2 = 78 hr). In addition to radiotheranostics, we investigate the decontamination of radiometals after inhalation. The hydroxypyridinone chelator HOPO demonstrates prophylactic efficacy in mice contaminated with Am-241.

Bio

Alexia Cosby graduated with a B.S. in Chemistry in 2017 from the University of Oregon after conducting research under Darren Johnson and Jim Hutchison. She then pursued a Chemistry Ph.D. at Stony Brook University under Eszter Boros. Her dissertation focused on utilizing luminescent lanthanides toward designing bimodal cancer imaging agents, using the phenomenon of Cherenkov radiation. Following graduation in November 2021, Cosby started her postdoctoral research in actinide chemistry with Rebecca Abergel at Lawrence Berkeley National Lab. Her postdoc research has focused on working with actinides in the context of in vivo decorporation and developing theranostic models with 89 Zr and 227 Th. Cosby intends to find a faculty position to continue studying the imaging and treatment of cancers using fundamental coordination chemistry.

In-situ Deformation of Metals under Hydrogen and High Pressure

Abstract

Understanding hydrogen degradation of metals is critical to the green hydrogen economy. Here, I will describe the synchrotron transmission X-ray microscopy (TXM) to image iron thin films that simultaneously undergo electrochemical hydrogen charging. This enables the observation of void-mediated crack growth, the coalescence of the primary crack with secondary cracks, and cracks and additional plasticity occur at grain boundaries during transgranular failure. These observations are discussed in the context of the prevailing hydrogen embrittlement mechanisms. Next, I will describe the use of diamond anvil cells (DAC) to compress lightweight alloys and nanoparticles under quasi-hydrostatic and non-hydrostatic stress. X-ray diffraction is used to monitor structural changes in-situ, and post-compression TEM is used to directly image these changes. We find that non-hydrostatic pressure leads to a significant increase in defect density, elevated strength and the nucleation and growth of precipitates in precipitate hardened Al7075.

Bio

Wendy Gu has been an Assistant Professor of Mechanical Engineering at Stanford University since 2017. Before this, Wendy received her MS/PhD from Caltech in 2014, and was a postdoc at UC Berkeley from 2015-2017. Her research focuses on lightweight architected materials, nanostructured metals and structural alloys, design and mechanics of energy materials (batteries, hydrogen economy, soft magnetic composites), and materials for extreme environments (e.g. high pressure). Major techniques within the group include nano-mechanical testing and in-situ imaging using transmission and scanning electron microscopy, synchrotron X-ray diffraction and imaging nano-synthesis and self-assembly, and 3D printing. Wendy is the recipient of the DOE Early Career Award, the ARO Young Investigator Award, the ACS Petroleum Research Fund Doctoral New Investigator Award, and the Hellman Scholar Award.
