ANALOG-HYBRID DYNAMIC SIMULATION OF THE FFTF REACTOR AND HEAT TRANSPORT SYSTEM

摘要

A mathematical model has been developed for investigating the dynamic response and control characteristics of the Fast Flux Test Facility (FFTF) Reactor and heat removal systems. The model was developed for solution on the analog-hybrid com¬puter facility at Pacific Northwest Laboratory (PNL). The mathematical modeling techniques used to simulate each system component are discussed in detail, and sample transient results are presented. Prospective uses of the simulation are also discussed.nOne complete heat removal circuit (out of four) is simu¬lated, and the total heat is accounted for by a multiplying factor. The reactor simulation includes point kinetics with temperature feedbacks, single-node representation of fuel, coolant, leakage, and reflector regions, and inlet and outlet mixing plenums.
