Standard material compositions derived from https://www.nist.gov and extended for the needs of SCALE.
Composition data is compiled from https://physics.nist.gov/cgi-bin/Compositions/stand_alone.pl?ele=&all=all&ascii=ascii2&isotype=all with removal of uncertainty and addition of AMPX/SCALE identifier. The data is extended to support man made occuring material compositions (e.g., SS304, zircalloy) along with material atomic weight ratio (AWR), and sigmaS, SigmaT, and nuSigmaF composition values.
