Hi all,
I am running test script for FISPACT-II-3.20 installation. I have found some warning messages in some case like in Tst_709/testresults/test128.log. Mine contains 11 warnings like this one:
> Log : nuc_no = 3347
> Log : nuclide name = Rn214
> 00001: Warning: nuclide_m:nuclide_collapse_fissyld: 1:
> cross-section data for fission (mt=18) not found
Is it a problem?
Best regards

Re: Cross-section data for fission not found
Hello Jan,
The warning message that you have is due to the existence of a fission yield file for Rn214 (half-life around 2.7E-07 seconds) from GEFY, where there is no fission cross section data. Indeed, since Rn214 is so short-lived there is no nuclear data file (even in TENDL)! Since there is no fission cross section, the fission yield data is not usable for inventory simualtions.
This is a code warning to let users know that the fission yield data is functionally ignored. For this case Rn214 decays quite rapidly so the fact that no nuclear data library considers Rn214 fission should not matter - FISPACT-II will alpha decay it to Po210.
Hope this helps.
Best regards,
Michael

Re: Cross-section data for fission not found
Hi Michael,
you are right. All the warning messages are for short-lived nuclides. It just surprised me, that there are no warnings in the default test results.
Best regards
Jan
