Abstract

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

马来西亚核电厂运行可能泄漏的137Cs扩散模型模拟

世界能源需求随着人口增长而增长。克服这一问题的另一种选择是建造核电站，这是一种廉价、清洁和安全的能源。马来西亚计划在2025年之前建造核电站，该核电站位于靠近印度尼西亚水域的地方。本研究旨在确定在马来西亚半岛东岸发生泄漏事故时，核电站释放的137cs放射性核素的分布模式及其对印尼海域137cs存在的影响。本研究采用定量方法，利用MIKE软件中的流体力学模块和输运模块进行情景二维建模。结果表明:核电站周边地区137cs浓度最高，为10 - 11 PBq/m 3，随后通过扩散和平流过程逐渐降低;在第15天，137 c的扩散将到达印度尼西亚水域，距离达76公里，并在第30天扩大，距离释放源达130公里。由于137cs的性质，它的运动遵循主导电流模式。在第15天和第30天后，由于平流和平流的影响，印度尼西亚海域137cs的存在将达到1 Bq/ m3
