Structure parameters and energies are calculated by computer simulation for faulted vacancy loops (VL) on the {110} plane in α‐Fe. The interaction between ions is described by a potential developed within the scope of the local pseudopotential theory. The size of the Frank VL dislocation core is found by comparing simulation results and continuum theory calculation. A structure simulation for small vacancy loops on the {110} plane without stacking faults with Burgers vectors b =〈100〉and b = (1/2)〈111〉 is performed.
