ICTP 2020

Radiation Damage in Nuclear Systems: from Bohr to Young

This event has been cancelled.

This Workshop will be held at the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy from 3 – 14 May 2021. It assists Ph.D. students and early-career researchers in developing a quantitative understanding of the impact of radiation damage on materials, both for existing fission and proposed fusion reactors. There is an emphasis on the conceptual progression of theoretical and experimental techniques across spatial scales from atomistic descriptions to the macroscopic behaviour of bulk material.

The IAEA actively supports research into radiation damage in order to help the development of resilient materials for use in the nuclear industry, medicine, fusion and space technology. More details of the conclusion of a recent IAEA Coordinated Research Project (CRP), Primary Radiation Damage Cross Sections, are available in the press release, New Data on How Chemical Elements React to Irradiation Available.

Further practical details are available at the ICTP website page for this event.
