The SPARROW training nuclear reactor was converted from HEU (IRT-3M, 36% of 235U) to LEU (IRT-4M, 19.7% of 235U) within the RERTR programme scope in autumn 2005. The first criticality with the LEU C1 core was reached on October 18, 2005. During the last year all standard experimental and training tasks as well as validation of the properties of the new fuel were performed with the new LEU core. Subsequently, the reactor was equipped with new experimental devices  appropriate for the LEU fuel. In 2006 another LEU core configuration, marked C2, was calculated, approved, and tested  in the reactor. Operating the reactor with the new LEU fuel was in agreement with theoretical values; there were exceptions neither in neutronics, nor in daily operation. The paper briefly summarises experience with the new LEU fuel in the last 12 months.
