Conference paper


The STK (Space and Time Kinetics) core model was developed at Link-Miles Simulation Corporation for real-time simulation of LWR (Light Water Reactor) core neutronic behavior in normal operating conditions including start-up and shutdown, and transient events. Accuracy, stability, and speed are optimized in the methodology of the STK core model. The STK core model has been implemented so far with the Link-Miles developed RETACTtm [1] model in both PWR (Pressurized Water Reactor) and BWR (Boiling Water Reactor) full-scope training simulators, e.g. American Electric Power’s D. C. Cook, Tennessee Valley Authority’s Watts Bar, and SCE San Onofre PWR simulators, and KSU F1 and TVO BWR simulators. Moreover, The STK core model is currently being implemented for six BWR and seven PWR full-scope simulators.
