NNL Distinguished Lecture

Dr. Peter Hosemann

Professor and Ernest S. Kuh Chair, Nuclear Engineering, University of California at Berkeley

 

Bio: Peter Hosemann is Professor in the Department for Nuclear Engineering and Mechanical Engineering at the University of California Berkeley and director of Manufacturing 360 research center and the associated shared user facility. Professor Hosemann received his PhD in Material Science from the Montanuniversität Leoben, Austria in 2008 while he conducted the research on lead bismuth eutectic corrosion, ion beam irradiations and microscale mechanical testing was carried out at Los Alamos National Laboratory. He continued his research at Los Alamos National Laboratory and joined the UC Berkeley faculty in 2010. Professor Hosemann has authored more than 300 per reviewed publications since 2008. In 2014 he won the best reviewer of the journal of nuclear materials award, the ANS literature award and in 2015 he won the TMS early career faculty fellow award and the AIME Robert Lansing Hardy award, the Brimacomb medal and was awarded the E. S. Kuh Chair of the college of Engineering at UCB.

 

Topic: "Materials Design in Nuclear Systems and Additive Manufacturing to Overcome Design Challenges"

Abstract: Nuclear applications represent some of the most demanding environments for materials today. The combined presence of radiation, high temperatures, corrosive conditions, mechanical stress, and extended operational periods presents a unique and formidable challenge. This convergence of factors complicates material selection and leads to phenomena not observed in other settings.

We present an approach for the design and selection criteria of materials for nuclear systems, along with various additive manufacturing and synthesis techniques that can address these challenges. Notably, we explore the use of graded materials through additive manufacturing (AM). Additionally, we will discuss how AM techniques can be employed to tailor the microstructure of materials, thereby optimizing their properties for use in nuclear environments.

Finaly, this presentation will cover different small scale mechanical testing techniques and how small scale mechanical testing can be deployed to provide insights in materials degradation and lifetime extension of nuclear reactors.
