MSR BC Question

[z.mau...@gmail.com]

I was looking at possibly using Moltres for simulating some fast spectrum MSR transients.

My question is the possible circulation of the precursors through the core and external circuit and then back to the inlet handled in Moltres?  The BC I see specified for the precursors block only refers to the outlet_boundaries.

Thanks!

This would be a great feature addition!!!

Katy - I am to take that as this ability does not exist at all currently? 

I'm not terribly familiar with how things are imposed in MOOSE.  But it should be straightforward to have the inlet BC consider the precursor concentration at the outlet of the core just scaled by the exponential of the time spent out of the core and the decay constant.  Or  would it be possible to model the entire external circuit, or some approximation of it, and have the precursors circulate around that? 

[Katy Huff]

Correct, we currently do not have a built-in method to tie the inlet boundary condition to the outlet boundary condition, but it is an area of particular interest for many of our upcoming research goals. Either solution you propose would be an advancement. Of course the first implementation would be quite a bit simpler than the latter, as you are certainly aware.

Greetings Zander and Katy.

I'm glad you asked about this Zander! Actually, it was one of the last things that's been added to Moltres. There indeed is capability to loop the precursors around at the moment. Check out the case here to see an example:

Ah, yes I see it in the LOSCA folder.  This is pretty much what I was looking for!  Thanks!

[Katy Huff]

Oh man -- I didn't realize! 

Sorry for the misinformation, folks.

No worries Dr. Huff! :D
