To study control and safety of accelerator driven nuclear systems, a one point kinetic model has been developed. It treats fast transients as a function of reactivity insertion, Doppler feedback, and the intensity of an external neutron source. The model allows for a simultaneous calculation of an equivalent critical reactor. Additional features are the possibility of inserting a linear or quadratic time dependent reactivity ramp which may account for gravity induced accidents such as earthquakes, the possibility to shut down the external neutron source by an exponential decay law of the form exp(-t/tau), and a graphical display of the power and reactivity changes. The calculations reveal that such boosters behave quite benignly even if they are only slightly subcritical.
