40000.03 corresponds with natural zirconium at 300K.
If the cross-section library includes natural elements, such in this case “Zr-nat”, you would be able to represent natural zirconium with a single identifier. Nonetheless, compositions based on natural elements, non isotopically decomposed, might have some limitations, e.g., in depletion calculations.
The command line option ‘-elem
’ decomposes natural elements (identified by symbol SYM at density DENS, into its constituent isotopes.
