Changes in version 2.1.32 related to the calculation of the average nuclide densities for micro-depletion (see: https://ttuki.vtt.fi/serpent/viewtopic.php?f=23&t=3689#p11908) make it necessary to include the volume of the homogenized zone to determine the ratio between fuel volume to the volume of t...

The radioactive neutron decay source is available from version 2.1.29 on. Note: if you are obtaining the ‘_nsrc.m’ file, it means you are running Serpent 2.1.32, and therefore, that the radioactive neutron decay source is implemented (also, you did not get an error message when you set it up). - Che...
You can check yourself: the Bateman equations solution either from TTA or CRAM/MatrixExponential is evaluated in ‘burnmaterials.c’ routine, 'N0'/'N', for both non-continuous reprocessing (BurnMaterials0) and continuous reprocessing (BurnMaterialsMSR) systems.
No, you have to convert the MCNP-format '.xsdir' to the Serpent-format '.xsdata'. In the same directory you should have the mcplib63 and mcplib84 files (photon data libraries), plus the '.xsdir' file (i.e. xsdir-mcp5-1.51-new.txt, from the link), and the 'xsdirconvert.pl' perl script (the 'xsdirconv...
Check the topic: viewtopic.php?f=26&t=1838, which provides the link of photon_data and additional photon data libraries from MCNP (mcnplib84 and mcnplib63) - as well as xsdir file (data is found under date 2012-01-06).
The topic is not going to provide much info anyway. Thinking about keeping certain compositions constant, might it be an option to adjust them between burnup steps (without changing the source - manual/automatic restart)?
Detectors provide flux/current or response/reaction rate estimates integrated over space, energy and direction (and time) domains. - Check Serpent units at Definitions, units and constants.
I re-ran the case only in neutron transport mode, with JEFF3.3 data ('.03c' - 293 K, '.06c' - 600 K and '.09c' 900 K) and TSL (be.00t and hh2o.00t - 294 K) downloaded from the OECD-NEA website: https://www.oecd-nea.org/dbdata/jeff/jeff33/index.html - without any problem! Note: the error comes from a...
