The electron beam energy of storage ring is 6 GeV, and the current intensity is 200 mA. After completion, it will be the first high-energy photon source in China. HEPS can provide X-rays with energy up to 300keV and has the capacity to build over 80 high-performance beamlines. The maximum energy of the HEPS beamline reaches 300KeV, which can construct more than 80 high-performance beamlines. Harmful radiation is inevitably generated, which becomes a direct source of radiation dose for workers during the operation and maintenance. Therefore, it is necessary to adopt a comprehensive shielding method of hut to contain harmful radiation. In this paper, the first step is to standardize the huts and analyze the types of radiation source terms. Secondly, the source term distribution and radiation dose attenuation inside the wall were simulated using FLKUA and STAC8. Finally, the shielding design thickness of the side walls, roof, and back walls of huts were given. PB - JACoW Publishing CP - Geneva, Switzerland ER -
