This is the final report on the second part of a series of centrifuge simulations to investigate long term instabilities in salt formations containing stored radioactive waste. The same materials (clay, loaded clay and gelatine) were used throughout. A new feature was the introduction of three-dimensional models of the same width as two-dimensional ones to verify results obtained with the latter. A system employing electro-osmosis to cut the clay was developed. Two-dimensional tests were conducted to reveal the causes of instabilities, their propagation and the part played by jets and fissures. The three-dimensional tests confirmed the results of the two-dimensional tests both for trigger points and for the shapes of the diapiric folds, at a more rapid rate.
