Objective

Different corrosion tubes were installed in the period 1985-1991 or will be installed in the near future. The aim of the present research programme is the completion of the corrosion experiments initiated in the previous programme and the beginning and completion of the operation of two additional corrosion tubes. This work has been initiated to obtain realistic corrosion rates for a large range of metallic and non-metallic materials (glasses, bitumen, concrete, and container- and overpack-materials).
The in situ corrosion experiments in the Boom clay underground laboratory were initiated to obtain realistic corrosion rates for a large range of metallic and nonmetallic materials (glasses, bitumen, concrete, and container and overpack materials). The aim of the present research program is the completion of the corrosion experiments initiated in the previous programme and the beginning and completion of the operation of 2 additional corrosion tubes.

One tube was overcored and the different sample (metallic, waste forms and surrounding clay) were prepared for analysis. The mass losses of the samples of another tube were determined. Samples were prepared for the different surface analyses, which are currently in progress. The concept of other tubes was revised and adapted to avoid problems of water accumulation in the tubes. The construction of both new tubes is finished.
Work programme:

Monitoring and controlling the ongoing corrosion experiments.
Design, construction and installation of the new corrosion loops.
Overcoring and retrieval of the different tubes in due time.
Analysis of the metallic and waste form samples and of the surrounding clay-core.
