Summary

Emergency situations for nuclear materials in the relevant facilities are provided for under French regulations. The decree issued on 12 May 1981 on the protection and control of nuclear materials currently specifies that "the Ministry of Industry can order a physical inventory of nuclear materials and compare it with audited records under all circumstances". These inventories can be stipulated for nuclear facilities, for example in the event of suspected theft, loss or diversion of nuclear materials. In such situations, operators must be able to check if all nuclear materials held are actually inside the perimeter of the facility and in the expected locations. To test the organisation in the sites involved at operator and competent authority level respectively, exercises have been regularly carried out. These exercises have been used to validate the methodology as well as the composition of the various crisis committees and the relations with the different units involved. In 2005, two operators of the Tricastin site, Eurodif and Areva NC were simultaneously involved. The scenario selected was based on the suspicion of the theft of one UF6 sample bottle associated with blackmail. During this exercise, a media pressure was exerted by professional journalists on the various implied entities: the two operators, the competent authority and his technical support body (IRSN). After a short overview of French domestic regulations, this paper describes the organization that has been implemented, then a representative from one of the operators and also the IRSN, present separately their respective experience feedback linked to this exercise.
