FISPACT-II Forum

Hello Michał, The example you sent had a couple of issues: 1. The number of energy groups is equal to the number of energies minus 1. 2. Please use full stops instead of commas in numbers - ie 1.00E+00 rather than 1,00E+00 3. You must have a 'wall loading value' after the flux values, typically use ...

Just to confirm, your arb_flux input is not valid. You must have n+1 energies (in eV) followed by n flux values. Then you run with GRPCONVERT n 709. Please try to fix the arb_flux and try again. If it does not work, provide a full set of inputs so that I can determine where the error is. Best regard...

Hi Michał, This isn't a minimum working example, as is, but I think there are at least two issues: 1. You list 130 energies in the first set, which corresponds with a 129 group structure. This is followed by 131 values for your spectrum. Your convert.i should have two numbers, the first should be 12...

Hello Michał, Thanks for contacting us through the forum. The FISPACT-II wiki has a page on spectra conversion: https://fispact.ukaea.uk/wiki/Spectra_conversion The general process is to provide one file with a list of the energies that bound your group structure (descending order), followed by the ...

Dear Reuven, Thank you for posting on the forum. FISPACT-II is primarily an inventory code, so if you have the spent fuel inventory you can input this using the FUEL keyword https://fispact.ukaea.uk/wiki/Keyword:FUEL Various options can be set, and cooling times specified, to generate outputs. This ...

The OECD-NEA is holding a FISPACT-II training course from 13th to 15th June 2018 at the NEA 92100 Boulogne-Billancourt (Paris): FISPACT-II, Inventory Simulation Platform for Nuclear Observables and Materials Science Those interested may submit an application through http://www.oecd-nea.org/confdb/co...

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 fi...

Dear Marco, FISPACT-II adds data to the pathways analysis when one of the solver-initation keywords ( ATOMS , SPECTRUM or STEP ) are used. In this simulation the various irradiation steps do not have any of these keywords and the first case has 0 flux: << ----- STEP#1 - DD 2.68 MW * 2y ----- >> FLUX...

The next workshop on TALYS/TENDL developments will be held at the Center of Accelerators and Nuclear Analytical Methods (CANAM) in Prague, over 13-15 November 2017.

The registration and abstract submission deadlines are 15 August.

For more details see the attached announcement.

Dear Unai, Thanks for putting this on the forum and pointing out an error message that should be improved. You are right, the issue is not use of COVARIANCE , but rather that you must use the NOERROR keyword ( http://fispact.ukaea.uk/wiki/Keyword:NOERROR ). Please add NOERROR to your input and let m...
