Based on the high safety significance of the Leak Before Break (LBB) concept for nuclear power plants (NPPS) with Soviet Pressure Water Reactors with electrical power 440 MW denominated as VVER 440 type 230, the International Atomic Energy Agency (IAEA) has decided to pay more attention to this important issue in order to assist countries operating these first generation VVERs. As part of the safety enhancement of nuclear power plants with VVER type 213 reactors, the leak before break concept has been applied to all NPPs operated in Czech and Slovak Republics. Lessons learned through statistical and mechanistic evaluations are presented.
