imposing inward current in criticality mode

Dear Serpent Team, I have a very basic question concerning the simulation of a set of fuel assemblies for a PWR. Is it possible to impose the incoming neutron current on the surfaces surrounding a set of fuel assemblies in criticality mode? I would like to compute the homogenised two-group constants...

Hexagonal detectors

Dear Serpent team, 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...

Photo-nuclear reactions

Dear Serpent developers, I would like to know if the current version (2.1.31) is able to model also the photo-nuclear reactions. I read the latest papers by Toni Kaltiaisenaho (M&C 2019 and Computer Physics Communications 2020) but I did not understand if the new models described there (including ph...

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: 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.
