An efficient full-domain method for plasma equilibrium reconstruction in iron-core tokamaks is described. Illustrative calculations and a comparison with results obtained from a finite-domain method using JET data are presented. The results show that both types of methods are in agreement with respect to global plasma parameters such as stored energy, internal inductance, volume and edge safety factor. However, when there is an uncertainty in the magnetic flux loop measurements, the full-domain method yields a more accurate separatrix location.
