The GAMIN technique is used to measure flux damage in Rapsodie. The principles and applications of this technique are described in an appendix; some typical results obtained with various types of reactor are given. This technique allows the flux damage induced in a graphite detector to be measured. It also enables the activities induced in a Ni detector to be established, thus permitting the index of the graphite/nickel spectrum to be determined directly. The parameters are measured at various different positions around the core- reflector boundary of Rapsodie for different environments. It is found that although these parameters are relatively insensitive to the environment, they vary very rapidly along a radius of the reactor in this zone (about 40% for 33 mm). These measurements are applied to determining the fluences received by steels and graphites. The high dose irradiations effected with Rapsodie can be analyzed in this way and compared to those effected with OSIRIS using the same method. (FR)
