The heavy-fermion compound URu(2)Si(2) is studied by X-ray diffraction in a diamond anvil cell at room temperature and high pressure. Its tetragonal structure is stable through the pressure range up to 50 GPa. The bulk modulus B(o) = 247 GPa and its pressure derivative B(o)' = 4 are calculated by fitting the V(P) data to the Birch and Murnaghan equations. Its pressure behaviour is compared with that of other heavy-fermion systems.
