Volume for depletion

User Support

I am running a depletion simulation on a CANDU reactor, and I define my materials using the following code,

69a3c8356bb67c8062f8eb625298ef4a564×209 8.84 KB

which I then call when constructing the cell in this code,

I was just wondering how the volume was managed here. When I allocate volume to the material, and then assign that material to multiple cells, which make up a greater cell, does the volume get spread out, or does it get duplicated. I need to know if I’m assigning the volume for the entire bundle, or for individual sheaths. Thank you in advanced.

The material volume is assumed to be the total volume of any shapes which are filled by it.

For example, if i have 5 cylindrical fuel elements, each have the volume of 100 units. Then I fill all of them with material_A, then the volume of material_A is:

material_A.volume = 5 x 100

Now if I have a universe_X, which 80% of it is filled by material_A. Then I fill all cylindrical fuel elements on the above with universe_X, then the volume of material_A in this model is:

material_A.volume = 0.8 x 5 x 100
