We studied the dependence of the superconducting transition temperature TSC on the residual resistivity in the ferromagnetic superconductor URhGe. The strong suppression of TSC caused by defects was observed. Superconductivity is completely destroyed when the mean free path falls below the superconducting coherence length, suggesting unconventional superconductivity.
