DPA Calculations

Post by ianyounker » Fri Nov 01, 2013 10:55 pm

I am trying to do DPA calculations in Serpent. My detector input was:

det 5 dm FeCrAl dr -444 FeCral

where FeCrAl is my material and -444 is the response function I believe is related to DPA cross sections.

My detector output was 0. Any thoughts on how to correct this? Is Serpent capable of doing DPA calculations?

Thanks

Ian

Which code version and cross section data are you using? The cross section libraries distributed with the code do not have DPA cross sections, but I think you should get an error message instead of zero results.

Serpent version 1.1.17. I am using ENDF B7 cross sections.

If the cross sections are from the Serpent 1 installation package, the DPA cross sections are not included in the data. We are planning a new release of cross section libraries (possibly before the official release of Serpent 2), in which this problem will be fixed.

ianyounker: I've made a (python) script that calculates DPA collapsed from a 100-group calculation, given as input the 100-group flux where you want the DPA calculated. It has elemental (or, where available, compound) 100-group DPA cross-sections from the ANL SPECTER code manual and calculates DPA for some predefined materials (HT9, SiC, D9, T91). It very straightforward to add your own material composition. All you need is to define a 100-group flux detector in Serpent with the right group structure. You can email me if you'd like to use it -- staffanq@gmail.com
