Supplementary cooling system for the spent fuel pool This system will be made up of fixed parts and mobile parts, the latter being deployed by EDF’s Nuclear Rapid Intervention Force (FARN). Cooling water intake Hot water discharge Spent fuel pool Pump Contaminated water treatment unit This unit will reduce the contamination of water in the reactor building following a core meltdown accident. It will be deployed by EDF’s Nuclear Rapid Intervention Force (FARN). Completion of the implementation of the « hardened safety core » These additional works will complete the implementation of the «hardened safety core» which will then be fully operational. In an extreme event, it will allow functions to be performed that are vital to ensuring the safety of the facilities and on-site emergency management. Improved reactivity management EDF plans to install a new high-pressure borated water injection pump in the primary system and to add four shutdown control rods to the reactor core. Second phase of the works Usually takes place six years after the ten-yearly outage. Containment Cooling water intake Hot water discharge Heat exchanger Pump Ultimate containment cooling system This system will remove the heat from the reactor building in the event of a core meltdown accident using a heat exchanger and a pump. arried out d beyond Conditions for the continued operation of 1,300 MWe reactors beyond 40 years • 23
