Re: Number of Depletion Regions effecting Max NPG / MPI ratio

Yes, I just tried running in debug mode, and the volumes I originally approximated using the approximator and then corrected to the precise value post-hoc. So the volumes should be good.

Number of Depletion Regions effecting Max NPG / MPI ratio

I've been attempting to run some PWR lattice cases on TITAN and I'm encountering a sort of odd behavior. I find I have a case that runs fine with a given NPG setting and the problem distributed over X amount of MPI tasks, but when I increase the number of depletion zones I find that the runs don't c...

Fission Power Normalization

Is there any quick way to normalize to Fission Power rather than Heating Power? We are trying to do some code to code comparison and want to normalize to fission power.

Thank,

Re: generate random particle or pebble bed files for HTGR calc

The original algorithm used by SERPENT to perform random particle dispersion was initially based on a simple location sampling and rejection routine. In this routine, points were randomly selected within the geometry and assessed to ensure that the point was both a particle radius away from the boun...

Re: Discontinuity factors (version 2.1.13 / 2.1.14)

I was looking at maybe using the symmetry option in the ADF card, but I don't think it will currently support the model I'm considering. In the image below, you can see that the assembly has rotational symmetry which I don't think can be replicated with the current ADF symmetry options. Would it be ...

Re: Discontinuity factors (version 2.1.13 / 2.1.14)

This thought just occurred to me, but you mention where you can use planes as the surface over which to calculate the ADFs. Can I specify multiple surfaces for a given universe ADF calculation to construct a rectangle?. Again, this is because I'm considering a geometry with a rectangular shape rathe...

Re: Detector response functions

I just had a couple of quick confirmation questions: 1.) Does response function MT -8 still correspond to total fission energy deposition? 2.) The total fission energy deposition does include (n, gamma) and fission gamma energy contributions, correct? If not, is there a detector that does? Also, how...

Re: Discontinuity factors (version 2.1.13 / 2.1.14)

Would it be possible to add the rectangular cylinder "rect" as a supported geometry for discontinuity factor calculations?
