Mass balance of Bright-lite facilities

[jimcc333]

Noticed the following issues:

• The capacity of the source facilities don't affect the burnup or operation of reactors even when the reactor needs more mass that the capacity of source. This is true in both forward and backward mode.
• The capacity of the sink facilities also don't affect the operation of reactors. Mass seems to disappear regardless of sink capacity.
• The above issues seem to break connected reactors in open cycles, see examples/open_LWRtoMOX.xml. Inreasing upstream LWRs don't resolve mass issues.

The burnup is unaffected because it is independent of mass. Our burnups are calculated per kilogram of material (hence MWd per kgIHM). We also (and I just realized this) are only putting a constraint on the maximum fuel we can receive per batch, but not a minimum. We are reverse Jurassic parking it by assuming we can't go below the constraint when in fact we can.

The sink capacity doesn't matter because we just remove the whole material not a mass, it is assumed the repo has enough space. This should be changed though. Not sure why the DRE isn't taking care of it. If too much fuel is offered then it should reject the trade. I will look into it.

I will open separate issues for each of these.

I just pushed an update so that the reactor warns if there wasnt enough (coremass/batches) received FYI On Mar 5, 2015 12:22 PM, "FlanFlanagan" notifications@github.com wrote:

Update:

Here some mass balance issues that still need fixing:

• When multiple reactors are connected to one source facility and the source facility is out of capacity, simulation segfaults
• Sink facility behavior
