Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Preliminary results from a nonlinear dynamic model of the Molten Salt Demonstration Reactor (MSDR) plant are presented. This model is coupled to an integral economizer Once-Through Steam Generator (OTSG) model with variable boiling length to simulate operation at different power levels. The reactivity effect of Xe-135 is also integrated to investigate open-loop load-following operation. Simulation results show that the reactor model is stable for the investigated reactivity perturbations. A load-following excursion is simulated by varying the feedwater flow rate through the steam generator. Results show that the MSDR can follow load demand in a stable manner through temperature-based reactivity feedbacks alone without requiring operator input. Future work involves development of instrumentation systems and control strategies to achieve near autonomous plant operation.
