ADVANCED MATERIALS AND MANUFACTURING

The vision of the AMMT program is to develop materials as an integrated part of advanced manufacturing. An application-based materials design and development approach is used, integrating functional requirements, characterization, manufacturing data, AI/ML and modeling and simulation.

R&D in this technical area includes:

  • Advanced materials development
  • Advanced manufacturing technologies
  • Traditional manufacturing methods

RAPID QUALIFICATION

Rapid qualification is the focus of the AMMT program. We will address the challenges associated with the qualification of high temperature materials for nuclear construction, the qualification of materials for environmental effects including irradiation and corrosion, and a paradigm shift from traditional methods in qualifying advanced manufacturing.

R&D in this area focus on:

  • High-temperature materials qualification
  • Advanced manufacturing qualification
  • Digital/model-based qualification framework

ENVIRONMENTAL EFFECTS

Material evolution and lifetime in harsh advanced reactor environments must be part of a reactor material development and qualification program. The Environmental Effects technical area covers materials degradation for topics of concern to the NRC that are not covered by ASME, including corrosion and irradiation effects on mechanical properties.

R&D in this area includes:

  • Performance evaluation under neutron irradiation
  • Accelerated irradiation effect qualification
  • Corrosion effects in nuclear environments

TECHNOLOGY MATURATION

To connect the development and qualification efforts to applications, the AMMT program incorporates technology demonstration as a core component. The goal is to enable technology transfer to stakeholders, and, by extension, use of materials and techniques developed by the program in existing and to-be-built nuclear reactors.

This technical area addresses:

  • Component fabrication and evaluation
  • Codes, standards and regulatory acceptance
  • Supply chains
