Welcome to the Nuclear Data Management and Analysis System (NDMAS) portal.


NDMAS comprises databases, a team of data scientists, and web-based tools for analysis and display of data from INL's nuclear fuel and materials research programs. 


Access to NDMAS from outside INL is provided on a per-project basis, by permission of the relevant managers. To request access, click here and include in the body of the email which program data you would like access to.
