Abstract (Englisch)

FEBEX II consists in the extension of the operational phase of the FEBEX (I) insitu test until the year 2001, prior to proceeding to its dismantling. It is also planned the extension, until quite-saturation, of the heating phase of the mock-uptest; design and construction of a geochemical mock-up, and some complementary laboratory tests, as well as modelling works. The good performance of the whole system, justifies the prolongation of the FEBEX tests two additional years in the case of the in situ and for as long as needed to get close to saturation in the case of the mock-up, while the heating and monitoring systems remain operative. It is planned dismantle only one of the heaters of the in situ test during FEBEXII, leaving the second to continue the heating and buffer saturation.
