The shielding design of the 8-GeV class X-ray Free-Electron Laser facility at SPring-8, SACLA, has been accomplished by using a semi-empirical code, SHIELD11, and Monte Carlo codes, EGS4 and FLUKA for the bulk shield. These results were compared with each other. The Beamline hutches of SACLA have also been designed and the leakage doses have been estimated including the incident conditions of the abnormal electron aberrance. SACLA is now being operated stably with sub-angstrom oscillations without any radiation problems.
