Information × Registration Number 0210U005812, 0110U005934 , R & D reports Title Development of probabilistic model for Level 1 Probabilistic Safety Assessment for internal initiating events for partial power state and shutdown state for power unit with VVER- 1000/ 320 popup.stage_title Head Kocharyants Oleg Rafailovich, Registration Date 17-01-2011 Organization State enterprise "State Scientific and Technical Center on Nuclear and Radiation Safety" popup.description2 The object of study:modern methodology of the probabilistic safety analysis (here - PSA) as recommended by the International Atomic Energy Agency (here - the IAEA), reference levels Western European Nuclear Regulators' Association (WENRA) and the best international and country-Nogo experience in the implementation of PSA. The purpose of RE Phase - I (reserch effort):collection of baseline data to develop of probabilistic safety assessment model of a Level-1 on internal initiators at the reduced level of power and the state of "stop" for power VVER-1000/V-320, as well as analysis of existing modern methodologies PSA. Research method Analytical method.Work Results:Intermediate report on implementation of this reserch effort, contains of the analytic analysis results of domestic and international experience, information regarding the necessity of benchmark data of unit's systems and components duaring reduce power and are able to "stop", including the analysis of the impact on the Routine Repair PSA changes, imposed by on the power, information on the initiating events frequencies and the safety equipment parameters that will be used to develop a probabilistic model. Specified probability model will complement the probabilistic model of a Level-1 on internal initiators of events related to violations in NPP with VVER-1000/V-320 at nominal power level.
