Simulation of Dispersion Modeling of 137Cs for the Possible Leakage of Malaysia’s Nuclear Power Plant Operation

The world’s energy needs increase in line with population growth. One alternative to overcome this problem is the construction of a nuclear power plant, source that cheap, clean, and safe. Malaysia has plan construct plants by 2025, which located close Indonesian waters. This study aimed determine distribution model 137 Cs radionuclide released plant event leak east coast Peninsular its impact on presence A quantitative method was used scenario 2D modeling using hydrodynamics module transport MIKE software. results showed highest concentration would be found area around value 10 11 PBq/m 3 , then it decrease through diffusion advection processes. On 15 th day, spread reach waters distance up 76 km expand 30 day 130 from source. movement follows dominant current pattern due nature. after days 1 Bq/m
