Description

The paper deals with the structural integrity integrity of the diesel generator set (genset) foundation system aimed for the emergency power supply plant in a Nuclear
Power Plant. 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 simultaneously
exposed to the seismic load, the short circuit impulse, and the synchronization failure load. The
problem is solved via the finite element method (FEM) by means of a commercial FE tool. 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.

Keywords genset, seismic loading, Finite Element Method
