FIGURE 6.1.21. Partitioning-Transmutation Fuel Cycle Diagram<br />

* Irradiating the reload to a burnup <strong>of</strong> 33,000 MWd/MTHM<br />

* Discharging and decaying the reload for 1-1/2 years<br />

* Reprocessing the U02 and MOX fuels together<br />

* Sending the TRU-contaminated wastes to the fuel reprocessing plant waste treatment<br />

facility (FRP-WTF) for partitioning<br />

* Returning the recovered TRU and the TRU-depleted wastes to the reprocessing plant<br />

* Combining the recovered actinides with the processed MOX and transporting the mixture<br />

to the refabrication plant, after a 6-month delay<br />

* Adding sufficient uranium to the MOX product to achieve the desired end-<strong>of</strong>-cycle reactivity.<br />

(This product is in powder form and contains the waste actinides.)<br />

* Refabricating the MOX product<br />

* Sending the TRU-contaminated wastes from refabrication to the fuel fabrication plant<br />

waste treatment facility (FFP-WTF) for partitioning<br />

* Returning the stream <strong>of</strong> recovered actinides to the fabrication plant<br />

* Incorporating the recovered actinides with MOX recycle streams within the facility<br />

* Sending TRU-depleted wastes to a mined geologic repository.<br />

Simultaneously, the fresh enriched U02 fuel is fabricated in a separate facility. At this<br />

point, the cycle is completed with the fabricated fuels being inserted into the reactor. The<br />

details <strong>of</strong> the waste treatment facility (WTF) process and plant design are given in Tedder et<br />

al. (1980) and Smith and Davis (1980).
