Re: Serpent-compatible ACE libraries with NJOY

Hi Jaakko, I was finally able to reproduce fast cross-section for the SERPENT. Now I have good results with keff 1.06156 (with libraries) and 1.05997 (I'm with libraries generated). The problem was a little silly, I found two errors in njoy the input file. First, it was a duplicate slash character i...

Re: Serpent-compatible ACE libraries with NJOY

Hi Yaakko, Sorry for bothering with this issue again. Actually you were right, with the 396 version in njoy99 I had values of the order of 10 ^ 50. Already with the njoy99.259 this does not happen more. But my keff remains high (1.12022) compared the standard libraries of the serpent (1.05819). This...

Re: Serpent-compatible ACE libraries with NJOY

Thanks Jaakko, i will look in to ACE file that i produce and search for this strages values. In the mean time, could you send me a link for your version of NJOY99? I think you use de 259 version.

thanks again,

Antolin

Re: Serpent-compatible ACE libraries with NJOY

Hi Yaakko, yes ACEs file that I generated was made with the njoy input I posted. Just to remember, i use the 396 version of njoy 99. I get the ENDF file https://www-nds.iaea.org/public/downloa ... B-VII.0/n/
thanks,

Re: Serpent-compatible ACE libraries with NJOY

Hello guys, I am starting to use NJOY99.396 to generate cross sections at different temperatures. Reading this topic I wrote the input file in njoy with the parameters that are in PDF Cross Section Libraries for Serpent 1.1.7. For test purposes I generated data to the U-235 and U-238. When I run the...
