Evaluation of NEMP vulnerability on cots electronic equipments

This study deals with a new evaluation method of NEMP (Nuclear ElectroMagnetic Pulse) vulnerability on cots electronic equipments. The method consists in comparing EMC (ElectroMagnetic Compatibility) test severities to NEMP conducted stresses. The comparison uses five characteristic criteria of the induced stresses, calculated with an analytic method. The process is based on a software named “SUSIE” (in French: SUSceptibilite a l'IEMN ≪ Impulsion electroMagnetique d'origine Nucleaire Haute Altitude ≫). Today, only conducted stresses are analyzed. An evolution is planned in 2013 to determine the equivalent vulnerability of radiated stresses and to validate the software.
