Design study of a French nuclear plant under aircraft impact according to German guidelines

Subject of the paper is the presentation of an aircraft protection for the reactor building and the electrical building of the French nuclear plant P'4 or N4 against the aircraft impact load conditions according to German guidelines. Furthermore, floor response spectra in the interior of the two buildings are evaluated for the induced vibrations resistant design of components. The presented solution leads to acceptable values of either necessary bending and stirrup reinforcements and of the level of equipment accelerations for the reactor building as well as for the electrical building.
