Adding a Separations Facility

The separations facility will request all the commodities in its Feed Commodity List, and separate them into any number of streams, plus a waste stream.

The following is the input template for Cycamore::Separations archetype:

<facility>
  <name>SeparationsFacility</name>
  <config>
    <Separations>
      <feed_commods>
        <val>[string]</val>
      </feed_commods>
      <feed_commod_prefs>
        <val>[double]</val>
      </feed_commod_prefs>
      <feedbuf_size>[double (kg)]</feedbuf_size>
      <throughput>[double]</throughput>
      <leftover_commod>[string]</leftover_commod>
      <leftoverbuf_size>[double (kg)]</leftoverbuf_size>
      <streams>
        <item>
          <commod>[string]</commod>
          <info>
            <buf_size>[double (kg)]</buf_size>
            <efficiencies>
              <item>
                <comp>[nuclide]</comp>
                <eff>[double]</eff>
              </item>
            </efficiencies>
          </info>
        </item>
        ...
      </streams>
    </Separations>
  </config>
</facility>

• Our feed commodity list should include both:

  • Used-UOX-Fuel

  • Used-MOX-Fuel

• The maximum feed inventory is the most feed material that we’ll have on hand: 1000 tonnes.

• The maximum separations throughout is the size of our plant: 80 tonnes/timestep

• This simple scenario will have a single output stream: Separated_Fissile

  • we will hold no more than 5 tonnes of separated material on hand at any time

  • 99% of all Pu (94000) will go into that stream

• all other material will go to Separated_Waste

Filling in the template, the input block looks like:

<facility>
  <name>SeparationsFacility</name>
  <config>
    <Separations>
      <feed_commods>
        <val>spent_uox</val>
        <val>used_mox</val>
      </feed_commods>
      <feed_commod_prefs>
        <val>1.0</val>
        <val>1.0</val>
      </feed_commod_prefs>
      <feedbuf_size>1000E+3</feedbuf_size>
      <throughput>80e+3</throughput>
      <leftover_commod>Separated_Waste</leftover_commod>
      <leftoverbuf_size>1000e+3</leftoverbuf_size>
      <streams>
        <item>
          <commod>Separated_Fissile</commod>
          <info>
            <buf_size>5e+3</buf_size>
            <efficiencies>
              <item>
                <comp>94000</comp>
                <eff>0.99</eff>
              </item>
            </efficiencies>
          </info>
        </item>
      </streams>
    </Separations>
  </config>
</facility>
