“…Dispersion parameter is a parameter that is analyzed and written on the Safety Analysis Report (SAR) as part of Chapter on NPP accident analysis. Dispersion parameters can be estimated using Gaussian Plume Model (GPM) as used in computer codes TREX (Hungary), MACCS (Taiwan, USA), OSCAAR ( Japan), LENA (Brazil ), and using Lagrangian Plume Model (LPM) as used in computer codes HYSPLIT (USA), NAME III (UK), MINERVE-SPRAY (CEA-France) [1,2,3,4,5,6,7]. Estimation data of dispersion parameters for Muria Peninsula site plant simulation analyzed using the PC-Cosyma code has been successfully carried out [8,9].…”
