PSA Applications for Dukovany NPP

Original language description

Reliability and Risk Department in ÚJV Řež, a. s., the Czech Republic, has developed and currently maintains Living PSA project for Dukovany NPP, a four-unit nuclear power plant in the Czech Republic. RiskSpectrum® PSA software has been used for development and quantification of the Living PSA model. It is an integrated model which comprises all initiating events, including internal and external hazards, for all plant operational modes in the same project. The PSA model is continuously updated and used extensively for various PSA applications at Dukovany NPP, such as risk monitoring, evaluation of Technical Specifications, event analysis, analysis of plant modifications etc. The use of the selected PSA applications to support Dukovany NPP risk management is required by the Czech implementing Decree and supported by the Czech regulatory guides. The paper describes the selected PSA applications at Dukovany NPP that have been performed recently, namely evaluation of Technical Specifications and requirements for availability of diverse and mobile (DAM) equipment. This evaluation follows the respective Czech regulatory guide. Several changes have been subsequently done in the plant Technical Specifications based on this evaluation. The paper also discusses the other recently performed PSA applications at Dukovany NPP as well as their outputs.
