    \caption{Fuel cycle facilities and material flow between facilities for modeling the 
    transition to advanced reactors with a limited recycle fuel cycle. Before 2025 a once-through 
    fuel cycle is used with the facilities in blue. Facilities in red are deployed starting 
    in 2025. In all limited recycling scenarios the spent UOX from the VOYGRs is sent from the 
    red Cooling Pool to the 
    Separations facility. In Scenarios 14 and 17 the spent UOX fuel from the Xe-100 and 
    MMR are also sent from the red Cooling Pool to the Separations facility, but they 
    are sent directly from the red Cooling Pool to the Repository and are not reprocessed 
    in Scenarios 15 and 18.}
