Abstract
The ASME construction code books specify materials
and fabrication procedures that are acceptable for pressure
technology applications. However, with few exceptions, the
materials properties provided in the ASME code books provide
no statistics or other information pertaining to material
variability. Such information is central to the prediction and
prevention of failure events. Many sources of materials data
exist that provide variability information but such sources do
not necessarily represent a consensus of experts with respect to
the reported trends that are represented. Such a need has been
identified by the ASME Standards Technology, LLC and initial
steps have been taken to address these needs: however, these
steps are limited to project-specific applications only, such as
the joint DOE-ASME project on materials for Generation IV
nuclear reactors. In contrast to light-water reactor technology,
the experience base for the Generation IV nuclear reactors is
somewhat lacking and heavy reliance must be placed on model
development and predictive capability. The database for model
development is being assembled and includes existing code
alloys such as alloy 800H and 9Cr-1Mo-V steel. Ownership
and use rights are potential barriers that must be addressed.
