I am having a serious issue with a coupled neutron-gamma simulation where I need the energy deposition mode 3. I was successful in running my code using the ENDF/B-VII containing the KERMA data that you kindly provided here (viewtopic.php?f=15&t=3187&p=10293&hilit=kerma#p10293), but I'd like to run this simulation using the most updated version, library ENDF/B-VIII.
I processed the whole library with NJOY2016, and everything seems ok (I tried it in stand-alone neutron transport mode and it perfectly works) but when I run the Serpent input in the coupled mode with the new library, the following error message comes out,
Code: Select all
"Fatal error in function ReadPendfData: No KERMA data for nuclide 5010.03c mt = 3301 Simulation aborted."
I tried to process the ACE with different NJOY versions (2016 and 2021), different NJOY input files (also some examples taken from the NJOY guide itself) and I even tried ACE files not processed by me but already processed by the nuclear library evaluators (from ENDF-B/VII.0, ENDF-B/VIII.0, JEFF-3.3 and TENDL2019 website), but I still get this error, so I think that the problem has to be in Serpent.
Also, I do not understand why the MT 301 is indicated with 3301 in the code error message.
Finally, I am wondering how/where you got the ENDF/B-VII library that you provided at the link above. Could you please provide me even a single NJOY input that you used to process it? I am really stucked!
Thank you so much, any support is very welcome
