Simulation neutron-gamma transport

Hi everyone, yesterday I have received the update of Serpent 2 about the photon simulation. I would like an explanation or instructions as how to create the library in appropriate format from MCNP data and I would like to know how to use files that were linked in the email (photon_data.zip). In orde...

Re: Detector response functions

Thank you for answer! The problem is the result of the deterministic code that uses the results of serpent. We don't have any information on the power genereted by gamma, and in a Fast reactor could be useful to have informations on what happens in the reflector. We are using JEFF 3.1.1 like library...

Re: Detector response functions

For the mt -25 and -26 has to be inserted dr -25 void? Because with this sinthax (simply copied from the input, so materials are just here for simplicity) det _RR_MC_low dr -10 void dm medium_core_low dr -25 medium_core_low dr -26 medium_core_low de 2 the code tells me that the mt reaction -25 and -...

Bad statistic in thermal region

Hi everyone, I have problem related to the statistic in the thermal region of a fast reactor. The configuration of Serpent 2 at the moment is Pop=10000000 Inactive cycles=50 (the shannon entropy is still available? ) Active cycles=400 Number of few-energy groups=5 For reasons regarding memory occupa...

Scattering production matrixes

Hi everyone, I'm trying to elaborate the output of a calculation of few energy groups constants generation. I've seen in other posts that the "new" scattering matrix is transposed but when I try to reconstruct the matrix I have noted that the zero elements are in strange positions. Here is the outpu...

Re: Memory allocation failed

Hi jaakko, thanks for your help! For the composition: no, I just pass the compositions of the materials from a given table(my work is a benchmark test). The goal is elaborate a cross sections library starting from equal temperatures for all materials, and then change them. Infact the problem si veri...

Re: Memory allocation failed

Hi Jesse, let me explain the situation.I am doing a criticality simulation where the fission products are already part of the fuel composition. So I am not start from fresh fuel for a burnup calculation. The final target is the calculation of the cross sections for each unvierse relateted to the fac...
