Re: 2.1.32 - Sensitivity calculation and uncertainty propagation

I was wondering if there was any publicly available covariance data file that can be used in conjunction with this new capability? Or something that is part of the Serpent distribution that I missed? From a quick internet search, it sounds that the COVERX covariance data format comes from SCALE, and...

Re: Energy deposition mode 3: failure with burnup calculations

Using -nofatal does the trick. I see the same errors showing up but the job keeps on running. The photon library is from the MCNP6.2 package, MCNP_DATA/xdata/mcplib84. I don't see how it could be related to the library, though. Restarting from a burned fuel composition and performing a neutron/photo...

Re: Energy deposition mode 3: failure with burnup calculations

The code now stops due to an issue with the photon majorant: ***** Wed Nov 6 21:56:06 2019: - MPI task = 0 - OpenMP thread = 10 - RNG parent seed = 1573102268732 - RNG history seed = 3317565072202641724 - RNG history idx = 248810 Fatal error in function TrackMode: Photon total exceeds majorant (E = ...

Energy deposition mode 3: failure with burnup calculations

Hello, The following issue shows up in burnup calculations with edepmode 3 activated, at some point in the depletion calculation (2.1.31 version). It happens only when the burnable regions contain isotopes that are also present in non-burnable regions (here, as an example, Zr, present in both the fu...

Re: Where to get KERMA data

Actually I found a thread where this issue has already been reported with the solution (source code removed in readpendfdata.c:) lines 419-422: else Die(FUNCTION_NAME, "Mismatch in lowest energy of ACE and KERMA datas " "for nuclide %s (mt=%ld) \nACE: %.20E KERMA: %.20E", GetText(nuc + NUCLIDE_PTR_N...

Re: Where to get KERMA data

Hi Riku, Thanks again for sharing the library! One isotope (Th-232) has an inconsistency in the new Kerma data: Fatal error in function ReadPendfData: Mismatch in lowest energy of ACE and KERMA datas for nuclide 90232.09c (mt=3319) ACE: 9.99999999999999939497E-12 KERMA: 3.98999100000000002375E-03 It...

Re: Where to get KERMA data

Hello,
I would be really interested in trying out these new energy deposition models, and would need the library with the KERMA coefficients too.
Could you please re-post the above link (not working anymore)?
thanks and regards,
Nicolas
