SEISMIC EARLY WARNING SYSTEM FOR A NUCLEAR POWER PLANT

Reviews of several Soviet-built nuclear power plants have shown that most of them have an unknown earthquake safety or are under-designed seismically. In the cases where seismic strengthening of the buildings and equipment is not feasible due to economical, political and timing reasons, an active reactor protection system based on an earthquake early warning system may be the answer, similar to the one installed recently in the Ignalina Nuclear Power Plant (INPP) in Lithuania.
