New features or new archetype repo?

[abachma2]

In the slack channel we have started some conversations about potential new archetype features, and whether these new features should be added to Cycamore or if it's better to create a new archetype library. Some of the points of this discussion include:

• fuel type caps for a reactor (e.g., 10% of fresh fuel can be MOX, the other 90% have to be UOX)
• Place for Pyre -- AFRC archetype for pyroprocessing, aimed at safeguards applications (could maybe argue OpenMCyclus for this too).

One thing I regularly need is facility parameters that change over time, e.g., an enrichment facility that increases its SWUs at a given point or switches from natural U to LEU as feed material.

I have implemented this but would also be willing to include it in another repo with, say, advanced archetypes. Or discuss with you if there's a smart way to integrate it into existing Cycamore archetypes

There was an effort to do exactly this with recycle https://github.com/cyclus/recycle, which obviously didn't take off. Perhaps something we can look into for the hackathon

Thanks @jbae11 - I couldn't remember the name we chose or find this repo... I knew there was something...

Another new feature to think about is multiple regions in a core, like the driver and blanket in an SFR. Have a reactor archetype that can account for requesting both of those.

Extra material output (Best way - implement as toolkit)

Something like:

<misc_waste_commodity>
  <val>contam_water</val>
  <val>tritium_gas</val>
</misc_waste_commodity>
<misc_waste_cycle>
  <val>4</val>
  <val>5</val>
</misc_waste_cycle>
<misc_waste_mass>
  <val>100</val>
  <val>1</val>
</misc_waste_mass>
<misc_waste_recipe>
  <val>h2o_contaminated</val>
  <val>h3</val>
</misc_waste_mass>

and it will just create the material and offer to the DRE?

Another topic: I put OpenMCyclus into a repo owned by ARFC, but should we transfer it into Cyclus? Also for @dean-krueger's work, deciding the best place to host some of the already-developed archetypes.

From @jbae11: accounting for non-equilibrium core. Like in an LWR, using fuel initially at a lower enrichment and having fuel go through fewer cycles. Maybe define batch-specific information, or base it on time. Looking to get more accurate spent fuel compositions and prevent overestimating of other resources (like enrichment) when starting up a new reactor.
