Abstract
The integrity of the diesel generator set (genset) in the emergency power plant of a Nuclear Power Plant is considered. The genset consists of the diesel engine, the generator, and the common base frame on elastic spring-damper elements clamped to foundations. The genset is exposed to the seismic load, the short circuit impulse, and the synchronization failure load. The problem is solved via the finite element method (FEM). In the FE model, the diesel engine and the generator are represented with two lumped masses rigidly connected to the base frame with sets of massless bars. Strength criteria are specified according to the Russian Federal Codes and Standards in the Area of Atomic Energy Applications. The necessary number of spring-damper elements for preserving the integrity of the genset is determined.
