Materials Damage Session Overview
The Materials Damage Session led by Catherine Romano covers various topics such as issues for non-light water reactors, fusion systems, and radiation damage cross sections. The session aims to understand data gaps, identify solutions across DOE programs, and leverage international efforts to make actionable conclusions. Participants are tasked with removing institutional bias, creating a multi-program plan, and addressing material lifetime prediction challenges within limited budgets.

Session Goals Understand the state of the sigma-dpa/gas production data Identify the gaps Determine potential solutions that incorporate all capabilities across the DOE complex Identify cross cutting solutions (what other programs may be impacted?) Identify areas where other work can be leveraged i.e. international efforts Provide actionable conclusions
Charge to session participants Participate in discussion Remove institutional bias! Create a national, multi-program plan
Charge to Session Lead Facilitate the conversation to result in actionable information Table conversations best addressed outside of the session Assume I am a new program manager with no previous information and a background in general nuclear physics (easy role for me!) How do I solve my materials lifetime prediction problems within limited budget?
Questions to be answered What are the missions/programs that use the data? Who are the sigma-dpa (and other damage information) users? How is the sigma-dpa data used? What are the user needs? Are there gaps in the data that impact the user? How do gaps impact the mission? What are the available libraries? What is the state of the libraries?
Recommend solutions What are the facilities available to do irradiations? Pros/cons What are the capabilities to measure damage/dpa/gas production Pros/cons What are the theoretical modeling capabilities? Where do they need improvement? How can we improve them? What are the transport model capabilities? Where do they need improvement? How can we improve them? What is the overall predictive capability for materials damage? How can we improve it?
