William Zywiec Staff Scientist and Group Leader in the Nuclear Criticality Safety Division at Lawrence Livermore National Laboratory Abstract: Since the discovery of fission and subsequent first criticality of Chicago Pile-1, more than 60 criticality accidents have occurred throughout the world. These accidents are divided into two categories: those that occur during critical experiments or

Th-234: Lise Meitner and Internal Conversion and Otto Hahn – Nuclear Isomerism and the role of isomeric nuclei in nuclear condensed matter physics

1165 Etcheverry Hall

Dr. Mahnke Heinz-Eberhard email: ,     webpage:;sprache=en Abstract: More than hundred years ago, Lise Meitner and Otto Hahn intensively studied the decay of Th-234, working in close cooperation. While Otto Hahn discovered nuclear isomerism, Lise Meitner studied electrons closely related to the gamma transitions following the transformation of Th into Pa. Both, nuclear

Overview of INL RELAP5-3D system code and examples of application to reactor analysis.

3105 Etcheverry Hall 3105 Etcheverry Hall, Berkeley, CA, United States

Dr. Paolo BALESTRA ART-GCR Methods Lead Abstract: RELAP5-3D is the latest in the RELAP5 code series developed at Idaho National Laboratory (INL) for the analysis of transients and accidents in water–cooled nuclear power plants and related systems as well as the analysis of advanced reactor designs. The RELAP5–3D code is an outgrowth of the one-dimensional

Ab Astris ad Terram, ad Astra Iterum: Radiation Effects Engineering – An Overview

3105 Etcheverry Hall 3105 Etcheverry Hall, Berkeley, CA, United States

Greg Allen Senior Radiation Effects Engineer, Center for Space Radiation Lead Abstract: Radiation effects engineering is a highly multidisciplinary, rapidly growing field within the aerospace industry. NASA Jet Propulsion Laboratory's Greg Allen will be discussing the fundamentals of the field, focusing on Single Event Effects and the importance of accelerators such as LBNL's 88" BASE

Design of the first fusion laboratory experiment to achieve target gain

1174 Etcheverry Hall

Dr. Andrea (Annie) Kritcher Team lead in the Inertial Confinement Fusion program and Group leader in Design Physics The inertial fusion community have been working towards ignition for decades, since the idea of inertial confinement fusion (ICF) was first proposed by Nuckolls, et al., in 1972. On August 8, 2021 and Dec 5th 2022,the Lawson

A Youth Led Nuclear Victory at COP-27

Via Zoom

Ia Aanstoot, Stockholm In what is undoubtedly a first for Berkeley Nuclear Engineering, this week’s colloquium will be given by a high school student in Stockholm, who played a critical role in delaying the COP27 climate negotiations by three hours and fundamentally changed the outcome by making it include nuclear power. The climate crisis is

Radiation damage studies in metals and metal/oxide heterostructures through in-situ TEM

3105 Etcheverry Hall 3105 Etcheverry Hall, Berkeley, CA, United States

Djamel Kaoumi Associate Professor of Nuclear Engineering at North Carolina State University Abstract: When coupled to an ion beam accelerator, the spatial resolution of Transmission Electron Microscopy makes it an invaluable imaging technique to track the real-time response of microstructure under irradiation, shedding light on the mechanisms of formation and growth of defects in materials.

Proton therapy: a perfect slice of physics, mathematics, and biology

Via Zoom

Ke Sheng, Ph.D., FAAPM, Professor and Vice Chair of Medical Physics Department of Radiation Oncology, University of California, San Francisco Radiotherapy delivers an ionizing cytotoxic dose to both tumors and normal tissues. Research in the past decades has focused on reducing normal tissue dose. Protons emerged as an appealing modality for radiotherapy due to their

“Future Directions for Nuclear Energy”

3105 Etcheverry Hall 3105 Etcheverry Hall, Berkeley, CA, United States

Per F. Peterson Distinguished Professor William and Jean McCallum Floyd Endowed Chair Department of Nuclear Engineering Abstract Fission energy is currently the largest source of zero-carbon electrical power in the United States, but expanded use has stalled due to high construction costs, long schedules, and lack of policies that credit the low carbon emissions from nuclear

NASA Open Science: Space Radiation and Biological Effects

3105 Etcheverry Hall 3105 Etcheverry Hall, Berkeley, CA, United States

Dr. Sylvain V. Costes Space Biosciences Research Branch Chief Project Manager for Open Science for Space Biology (GeneLab/ALSDA) Director of the Radiation Biophysics Laboratory NASA Ames Research Center Abstract The challenges and risks associated with deep space missions require new knowledge discovery tools and biomedical support capabilities. To support this shift, biological data needs to
