Current Progress and Preliminary Shielding Design Analysis for Gamma Cell using MCNP

The design of indigenous gamma cell based on the basic safety criteria published by IAEA and AELB has been completed by PDC. One of the important safety criteria for designing gamma cell is shielding design. For this gamma cell, shielding thickness has been calculated manually and the shielding concept was designed based on the past experience in the development of other nuclear equipment and facilities. MCNP software has been used for verification to ensure the shielding design is complying to the requirement. The paper discussed about the preliminary result of shielding design of indigenous gamma cell using MCNP software. (author)
