Long-Term High Temperature Alloy Qualification examines material testing for qualification within ASME’s Boiler and Pressure Vessel Code, Section III, Division 5, as well as testing for concerns beyond what the ASME Code addresses. Most of this materials testing has been consolidated under the Advanced Materials and Manufacturing Technologies (AMMT) Program (https://ammt.anl.gov/), however, some legacy work continues under the Gas Cooled Reactor Program.

High Temperature Design Methodology seeks to improve the implementation of the ASME Code through improving analysis methods, updating design model methodologies, and development of new sections to address needs of high temperature gas-cooled reactor vendors.
