Hydraulic Analysis of the Contribution of Emergency Water to C. N. Almaraz Systems Affected as a Result of the Complementary Technical Instructions issued by the CSN after Fukushima

This paper presents the study and hydraulic analysis of the capacity required contribution of emergency water to the Almaraz NPP to power systems deal with the accidental events outside the bases of design defined in the Complementary technical instructions generated by the CSN after Fukushima. Through the program of balanced hydraulic SBAL, developed by entrepreneurs Grouped (EE.AA) and used in multiple security systems analysis, and based on designs and requirements to be fulfilled by the Almaraz NPP of the different strategies are set, have developed a series of hydraulic models that they have allowed the definition and dimensioning of the portable media and the new connections required in the central systems.
