The full exchange incorporates both the reactor requset parameters and the reactor supply parameters and adds a notion of repositories. In general, a repository is a back-end facility that bids on resources that could be used as advanced reactor fuel. As such, it ties both subexchanges together, requiring that they be solved as a larger exchange.
The full exchange requires a small number of parameters be defined in addition to the reactor request and supply parameters. Only the number of repositories and number of back end facilities for which a to-repository node will be added is needed. All reactor assembly nodes are considered candidates for repository arcs, and such arcs are chosen according to the exchange’s exclusion probability.
