Abstract

Analysis of dynamic response of nuclear power plant buildings under aircraft impacts on reactor containments A. Khrapkov, V. Petrov & I. Shkhinek Department of Structural Mechanics, The B. & Vedeneev All-Russian Research Institute of Hydraulic Engineering (VNIIG), St. Petersburg, Russia ABSTRACT The paper- reports the results of calculation analy- sis of the dynamic behavior of engineering struc- tures of a nuclear power plant reactor compartment under an impact of a crashing aircraft. against a reactor containment.

It is shown that in some cases inertia loads on equipment caused by aircraft impacts may prove to be higher than at MDE. INTRODUCTION In designing nuclear power plant buildings it is common practi
