In case of pipe rupture, an insufficient capacityof the siphon breakers may result in rapid dewatering of the fuelassemblies. The operator should examine this safety issue.Re‐evaluations of the performances of communications means will belaunched to allow the site and Corporate level to execute their tasksmore efficientlyRe‐evaluations of the performances of software calculating radiologicalconsequences will be launched to allow Corporate level to executetheir tasks more efficientlyDescription of the organization of the emergency plan and the logisticsadapted to take account of a multi‐unit accidentAn optimization study for mobile equipment and their storageinfrastructure (site or centralized) will be performed, also on the basisof the analysis of the EDMG14, 23 41 In progress 31/12/201335, 40 CLOSED 30/06/201243 In progress 30/06/201228, 34, 45 CLOSED 30/06/201245 In progress 31/12/2013480 KCD12 / PWR Power supply Total Station Black‐outImplementation of a 380 V emergencyelectrical gridInstall an alternative power supply (380V) for non‐conventional and/orsafety equipment (compressors, pumps, valves…)15, 26 In progress 30/11/2013481 KCD3 / PWR Power supply Total Station Black‐outImplementation of a 380 V emergencyelectrical gridInstall an alternative power supply (380V) for non‐conventional and/orsafety equipment (compressors, pumps, valves…)15, 26 In progress 30/11/2013482 KCD4 / PWR Power supply Total Station Black‐outImplementation of a 380 V emergencyelectrical grid483 KCD12 / PWR Power supply Total Station Black‐outImplementation of a 380 V emergencyelectrical grid484 KCD3 / PWR Power supply Total Station Black‐outImplementation of a 380 V emergencyelectrical grid485 KCD4 / PWR Power supply Total Station Black‐outImplementation of a 380 V emergencyelectrical grid486 KCD12 / PWR Power supply EDG autonomy487 KCD3 / PWR Power supply EDG autonomy488 KCD4 / PWR Power supply EDG autonomyProcedures to manage the autonomy ofelectrical diesel generatorsProcedures to manage the autonomy ofelectrical diesel generatorsProcedures to manage the autonomy ofelectrical diesel generators489 KCD / PWR Power supply EDG autonomy On‐site fuel transport490 KCD12 / PWR491 KCD34 / PWROperationmanagementOperationmanagementTotal Station Black‐outTotal Station Black‐out492 KCD12 / PWR Power supply Total Station Black‐outProcedures in case of total station blackoutProcedures in case of total station blackoutImplementation of a 380 V emergencyelectrical gridInstall an alternative power supply (380V) for non‐conventional and/orsafety equipment (compressors, pumps, valves…)15, 26 In progress 30/11/2013Installation of an alternative power supply (380 V) for the rectifiers 15 In progress 30/11/2013Installation of an alternative power supply (380 V) for the rectifiers 15 In progress 30/11/2013Installation of an alternative power supply (380 V) for the rectifiers 15 In progress 30/11/2013Provide a procedure defining the electrical loads that are not essentialin emergency situation, in order to limit the fuel consumption of thediesel generatorsIn progress 31/12/2012Provide a procedure defining the electrical loads that are not essentialin emergency situation, in order to limit the fuel consumption of theIn progress 31/12/2012diesel generatorsProvide a procedure defining the electrical loads that are not essentialin emergency situation, in order to limit the fuel consumption of theIn progress 31/12/2012diesel generatorsPurchase of tanker wagon to transport diesel fuel to the site, andevaluation of the necessary connection points17 In progress 31/12/2012Update an operating procedure in case of total SBO or LUHS (e.g., rapidcooling by means of steam generators)25 In progress 30/11/2013Update an operating procedure in case of total SBO or LUHS (e.g., rapidcooling by means of steam generators)25 In progress 30/11/2013Establishment of procedures for connection and start‐up of alternativeelectric power supplies 15 In progress 30/11/2013Implementation of activities13/20
