xGPT output

Dear Serpent Team, I am analysing the output of some sensitivity calculations run with the xGPT mode and I noticed that even if the input is something like sens pert custom 94239_MT18_1 efunc "94239_MT18_1.txt" zailist 942390 matlist fueli mtlist 18 sens pert custom 94239_MT18_2 efunc "94239_MT18_2....

Re: "no KERMA data" but ACE file contains them

Dear Riku, thanks for your kind reply. I attach you an NJOY input that I used to generate the library (the nuclide is Boron because its processing requires only a few sec., but the input files for the other nuclides have the same structure). I am not sure if MT 318 and other KERMAs are in the ACE fi...

"no KERMA data" but ACE file contains them

Dear Serpent Team, 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 ( https://ttuki.vtt.fi/serpent/viewtopic.php?f=15&t=3187&...

Re: Question regarding hex-y detector lattice

Dear Ville, I suspect that there is something wrong in the way Serpent associates the tallies to the assembly numbers. Checking the results of the attached results, you can see that the first assembly with non-zero power in the "_core0.m" file is the 243, while the first non-zero power in the "_det0...

Re: parsing sensitivity output

Hi Andrew, the Serpent version is the last one, the 2.1.31, while the serpentTools version is the 0.9.0! The output of grep is the following, 59:ADJ_PERT_KEFF_SENS = [ 63:ADJ_PERT_KEFF_SENS = reshape(ADJ_PERT_KEFF_SENS, [2, SENS_N_ENE, SENS_N_PERT, SENS_N_ZAI, SENS_N_MAT]); 64:ADJ_PERT_KEFF_SENS = p...

parsing sensitivity output

Dear Andrew, I am trying to use serpentTools to post-process the output of a sensitivity calculation. Your code is really awesome! I have a couple of questions. 1) Why does the code only print the results of the second last generation? Assuming 10 generations, if I type in the notebook the command p...

Re: huge RAM requirements in coupled photon-gamma simulation

Dear Jaakko,

thank you so much for your support. We extensively tested the coupled neutron-photon simulations and now it works quite well.

huge RAM requirements in coupled photon-gamma simulation

Dear Serpent developers, I have encountered an issue regarding coupled neutron-photon transport. When I run the coupled simulation, an error about memory allocation comes out. Looking at the RAM requirements: 1) 100k neutrons with "set ngamma 1" and requires 42% of the RAM (i.e. 42 GB) 2) 100k neutr...

Re: photon homogenized cross sections

Dear Jaakko, thanks for your answer. I would have another question regarding coupled neutron-photon transport. Since I cannot find the scattering matrices for photons, I would be happy even with one-group cross sections for photons (better than nothing, in my case), however, when I try to run the si...
