- 313 - The La Hague site Licensee's accident management organisation The licensee AREVA NC indicates that human resource management in severe accident situations would rely on the deployment of the facility personnel, personnel associated with the emergency organisation as planned for in the PUI, including the intervention agents (FLS) and on-call personnel. If necessary these resources could be reinforced on an alternating basis. Possibility of using equipment existing on the site The licensee has drawn up an inventory of the intervention means figuring in the PUI and the off-site emergency means that can be called upon. Their availability and intervention capacity in the event of a severe accident have been partially assessed. With regard to the alert means, particularly the PPI (off-site emergency plan) siren and population alerting system if the PPI is triggered in the reflex response phases, AREVA NC provides no information that confirms their availability in the event of a severe accident. The autonomy of the means of communication would be limited to a few hours. Beyond this AREVA NC envisages using carrier frequency transmission or a battery power supply. AREVA has drawn up an inventory of the fixed and portable environmental monitoring instruments available on the site. With regard to the crisis management premises, the robustness of the FLS building housing the PCDL (Local Strategic Management Command Post) and the PCS (Security Command Post) is limited to an earthquake of magnitude 5.3. This building is equipped for the management of a lasting emergency situation, with fixed beds, emergency electrical power supply, autonomous water supply, filtered positive pressure and radiological monitoring instruments. The hall grouping the First-Line Command Posts (PCA) for each facility is built to withstand the DBE. Measures envisaged to reinforce the accident management capabilities AREVA NC envisages reinforcing the human resources, particularly the intervention resources, by sharing with the group's other sites, but without detailing the conditions. For the material resources, various crisis management-related studies will be carried out. Avenues considered noteworthy by ASN are: the creation of resistant premises to accommodate the emergency organisation, ensuring redundancy with the premises normally provided for the PCDL; the reinforcement of the pumping means and the evaluation of the radiological impact around the site (trucks); the reinforcement of the internal and external communication means to ensure their availability. AREVA NC does not decide on or make any commitments regarding the implementation of reinforcement provisions. ASN considers that it is essential for AREVA NC to reinforce its material and organisational provisions for severe accident situations. ASN will issue requirements in this respect, more particularly concerning the emergency premises, the material resources and the means of communication. Mélox Marcoule Licensee's accident management organisation In its CSA report, Mélox makes reference to the emergency organisation described in its PUI. It provides details on the organisation of the permanence of PUI functions and supervision. Supervision permanence covers facility monitoring and detection in order to determine the nature and location of an event. The emergency organisation and means that would be implemented if an accident occurred on the Mélox facility are based on several resources at CEA Marcoule (CEA Marcoules PCD-L premises, FLS and SPR).
