Dear developers ,
The TRITON manual mentions the possibility of using the "ORIGEN-S number density file" ft71f001 to perform post-processing operations. So my hopeful guess is that it should be possible to do ORIGEN-S restart decay calculations - based on file ft71f001 ( automatically created after depletion calculation with TRITON/NEWT for a BWR assembly ).
However, my ORIGEN-S restart calculation, replacing SAS2H with TRITON/NEWT resulted in zero-values for nuclide concentrations for all decay steps. This is why I have two questions :
1) Is ORIGEN-S restart ( based on the combined results of the individual mixture results ) possible with ft71f001 ?
2) If the answer is "yes" :
What are the changes in the ORIGEN-S restart-file input compared to use of the ft71f001 file automatically created by SAS2H ?
Best regards,

Dear Gerhard,
You are very perceptive - you can in fact restart ORIGEN-S from an ft71f001 file, if you know what you are doing. However, at this time, it is not possible to restart TRITON from an ft71f001 file. TRITON always takes its initial concentrations from SCALE standard composition input, not from the standard composition data. TRITON would need to be updated to know to take initial compositions from the ft71f001 file instead. This is in my list of things do, but it will not happen until after SCALE 6 is released. The ft71f001 file is always written by ORIGEN-S, so it is always readable by ORIGEN-S, whether you start with SAS2H, TRITON, or ORIGEN-S. Is there a reason why you would want to follow a SAS2H calculation with a TRITON calculation? Why not just use TRITON for the full calculation?

Mark DeHart
