[en] A 0-D analysis of the performances of the FIRE and ITER-FEAT projects is presented. The two projects are compared with the same rules for the density and temperature profiles, impurity contents and τ^*_He/τ_E constraint, using three different scaling laws for the energy confinement time: IPB98(y), IPB98(y,1) and IPB98(y,2). With IPB98(y) scaling and FIRE rules for the profiles and impurity contents, the Q = 10 nominal operating point of the FIRE project is reproduced. With the same assumptions, the ITER-FEAT project is shown to operate at Q = 50. Using IPB98(y,1) scaling and FIRE rules for profiles and impurity contents, the maximum Q for FIRE is reduced to Q = 7.5 while an operating point at Q = 50 is still found for ITER-FEAT. Using IPB98(y,2) scaling and FIRE rules, the maximum Q for FIRE is reduced to Q = 4.3 while it is reduced to Q = 17 in ITER-FEAT. At last, using IPB98(y,2) scaling and ITER-FEAT rules for profiles and impurity contents, the nominal operating point at Q = 10 of ITER-FEAT is reproduced while the maximum Q in FIRE is reduced to Q = 2.8.
