Influence of seismic excitation on the drop time of control assemblies in PWR's
Abstract
In this paper the influence of seismic-induced vibrations on the drop time of control assemblies in a Pressurized Water Reactor (PWR) is investigated with the aid of numerical methods. This procedure is verified and qualified by a number of fundamental experiments. It is shown that the increase of the drop time due to seismic excitation is less than 1 s . This result remains valid for vibrations under broad variations of the main input parameters.
