Fire Protection in NPP: Challenges Posed by Fires to the Structures, Systems and Components of Nuclear Power Plants

摘要

This Report summarizes the results of the studies performed by the JRC/IE in 2007 on Task 2 of the SONIS research program which is devoted to the Safety of Nuclear Installations. The aim of this task is to identify the fire related parameters associated to the design basis scenarios for accidental and malevolent events, and to identify the Systems, Structures and Components where the vulnerabilities are important for the overall safety evaluation of the plants. This report collects information on standard qualification tests and on experimental fire resistance tests for cables and electrical cabinets. This report prepares the next step of the SONIS program which will consist in estimating (together with the main key players in the ¿fire¿ community from Europe, the OECD countries, The Russian Federation and the Ukraine):¿to which extent national norms are consistent nd covering all safety aspects¿if certain experimental programs are mature enough to allow qualification test definition for those components which still have noneThis work will be followed in 2008.
