This is quite an old post, but is there now an option to define LFP for larger simulations?

Hi Jaakko, When using the ARR's which have multiple region using the same nuclide is their listing in the ARR file as they appear in the geometry. I have a nested section in TRISO particles, so does this indicate that these are all grouped together in that universe. There should be three graphite re...
Hi Jaakko, I have tried these work around now and they get to the stage when they read the file, however the simulation causes a segmentation fault and crashes. The stages are; 0 : BU = 0.000 MWd/kgu, time = 0.00000E+00 days 1 : BU = 0.021 MWd/kgu, time = 1.00000E+00 days 2 : BU = 0.643 MWd/kgu, tim...
Hi Jaakko, The restart feature seems to only work on bu's greater than 0.1 MWd/kgU. In this case restarting with 0.177 works, however 0.088 does not and it produces the error below. Restart file "restartfile" contains the following burnup points: 0 : BU = 0.000 MWd/kgu, time = 0.00000E+00 days 1 : B...
When you include set inventory or daystep the results no longer normalsie. When Trying to manually normalize the results by using tot_lossrate the results are often 5-10% lower to if normalized by removing these features. Is there a different procedure for normalizing ARR's?
You get this error by mistakenly having one of your .09c files in your materials as a .06c instead. All of the nuclide endings have to be the same in a material or this error is shown, maybe implement a user error if they are not all the same?
Hi Jaakko, Can you just confirm that Serpent does not produce/print endf 27 and that it is the sum of mt 18+ the sum of (102 to 117). Also I am interested in 201, the total production. Is there any way of calculating this with 51- to 91? There is little information in the reference regarding how man...

Hi Ville, The simulation ran as expected and was providing reasonable results. The Volpower results were a bit odd though. I have 1 million fuel cells, these are produced as hexa and then split during the simulation. My Volpower output only had 13000 fuel cells produced any power in them, however th...
