The stability of the TF and CS cable-in-conduit conductors for the Internat
ional Thermonuclear Experimental Reactor (ITER) has been analyzed with the
code Gandalf. The energy margins, computed for a number of disturbance scen
arios, are in the order of some 100mJ/ccst, well above the expected disturb
ances. A detailed convergence study is shown to be essential not only in pr
inciple but also in practice, e.g. dual stability was found in some cases,
but disappeared when the integration time step was refined.
