SECURING SAFE OPERATION OF VVER REACTOR SYSTEMS IN NUCLEAR POWER PLANTS

摘要

The safe operation of VVER reactors has been discussed throughout the entire design process, taking account of the normative documentation, including the international requirements (IAEA, EUR). After the first domestic normative document "Basic principles for securing the safety of nuclear power plants" was approved in 1973, work began on the reconstruction of the first-generation VVER-440 power-generating units. The measures taken to increase safety concerned all types of reactors VVER-440 and -1000. Information on implementing these measures is presented.
