SUMMARY:Brew with the Crew: Accelerated Qualification of Novel Nuclear Structural Materials
DESCRIPTION:Join us for the upcoming technical talk —attend in person at Stockman’s Restaurant or virtually via (https://teams.microsoft.com/l/meetup-join/19%3ameeting_MGYxYTkzNmMtMzg0MS00MjdjLTkwYmMtOWNkMWMwNjMzOWFi%40thread.v2/0?context=%7b%22Tid%22%3a%224cf464b7-869a-4236-8da2-a98566485554%22%2c%22Oid%22%3a%2264d770c8-e8c2-4ef1-b2f4-1e7ebd03bd37%22%7d)\nTitle:\nAccelerated Qualification of Novel Nuclear Structural Materials: Multiphysics Simulations of a MEMS-Based Creep Device Under Ion Irradiation\nAbstract:\nQualification of structural materials for advanced nuclear reactors requires testbeds capable of\nsimultaneously replicating and monitoring high temperatures\, irradiation\, and mechanical stress.\nThis talk presents a multiphysics modeling framework for the design and optimization of an in-\nsitu testbed for measuring irradiation creep and thermal fatigue.\nThe testbed couples a silicon MEMS device with ion irradiation and scanning electron\nmicroscopy to enable real-time mechanical testing under irradiation. Finite element simulations\ndeveloped in CUBIT and BISON resolve the coupled thermal\, electrical\, and mechanical\nresponse of the MEMS device and quantify induced strain in the sample. Geometry optimization\nof the MEMS device is performed to achieve uniform temperature and strain fields in the test\nsample.\nResults demonstrate that the multiphysics framework reduces reliance on iterative physical\nprototyping in testbed development and provides a reproducible basis for geometry and loading\nparameter selection in nuclear materials testing.\nSpeaker: Akanksha Parmar\nPostdoctoral Research Associate\nIdaho National Laboratory\nAkanksha is a Postdoctoral Research Associate in C650 department at INL\, where her research\nfocuses on computational modeling of nuclear fuels\, including high burnup structure\, chromia-\ndoped UO₂\, and annular fuel pellets\, using advanced constitutive models such as crystal\nplasticity.\nShe received her Ph.D. in Mechanical Engineering from Purdue University\, where she combined\nmultiscale modeling with hands-on fabrication\, processing\, and characterization to study\nmicrostructure evolution during additive manufacturing. She holds an M.S. in Aeronautics and\nAstronautics from Purdue University\, where her thesis focused on multiscale modeling of\ncomposite structures.\nCo-sponsored by: INL-Idaho National Lab\nSpeaker(s): Akanksha Parmar\n1175 Pier View Dr\, Idaho Falls\, Idaho\, United States\, 83402\, Virtual: https://events.vtools.ieee.org/m/563911
