In this paper the effect of resonant magnetic perturbations (RMP) on the net radial transport of runaway electrons (RE) is calculated by simulating the RE drift orbits in magnetostatic perturbed fields. Through the transport, RMP influences the time dynamics and preferred loss directions of the REs. The distribution of the field mesh exit points of the runaway electrons become more localised compared to the unperturbed case, since the loss pattern depends on the geometric properties of the RMP configuration such as periodicity or helicity. On the other hand, the loss patterns do not depend on the particle energies and starting positions. The particle radial steps are correlated to the local radial magnetic perturbation component, which makes the transport chaotic, but deterministic.
