translation function

[Radiation-Transport]

The translating function to FENDL3.1c is generating mcard with some isotopes which are not in the XS.
See next example, also attached MaterialTS.txt

I will look into it

This is due to a logical mistake in the conversion of natural zaids. Indeed, if a correspondant natural zaid is not found in the requested library, an expansion is effectuated. Unfortunately the expansion is done without checking if every single zaid that is in the list of natural abundances is actually present in the library. A check of this type must be introduced whith some sort of redistribution of the missing precentage of the unavailable zaid(s) over the available ones.

The bug has been fixed as follow:

• now the availability of each zaid that compose the natural expansion is verified
• in case it is not available the availability in the default library is verified

If the zaid is not available even in the default library the conversion triggers the same error (and consequent error handling) of no possible translation with warnings both in cmd and log file. If this behaviour turns to be too harsh through user experience feedback, softer handling could be considered in the future (The extreme rarity of this chain of events should also be kept in mind). For the moment being the issue is closed
