Tinjauan dan pemilihan calon tapak loji janakuasa nuklear di Semenanjung Malaysia

Site selection of nuclear power plant (NPP) is one of the most basic safety requirements in the process of building a nuclear power plant facility. This study implemented the process of NPP site selection in Peninsular Malaysia based on the consideration of seven safety criteria recommended by the Malaysian Atomic Energy Licensing Board (AELB). The criteria involved are geology and seismology, hydrology, population, meteorology, safety zone, facility, and environmental impact. Analyses used in this study are Digital Mapping, Feature Overlay Analysis and Decision Making Analysis. The process of site selection is divided into two stages - survey stage and selection stage. In the survey stage, four potential sites were identified using Digital Mapping and Feature Overlay Analysis of mandatory criteria in ArcGIS 9.3 software. In the selection stage, the strengths and weaknesses of each candidate sites were discussed based on the site safety criteria by AELB. The comparison of strengths and weaknesses is translated into triangular fuzzy numbers. Pair comparison matrices were built from the triangular fuzzy numbers to calculate the site’s ranking using Fuzzy Analytic Hierarchy Process. The result of this study suggests candidate site 3 (CT3) in Mukim Jugra area in Kuala Langat district, Selangor State, as suitable NPP site for the construction of NPP in Peninsular Malaysia. The site criteria in CT3 have complied seven safety criteria based on the document ‘Guideline for Site Selection for Nuclear Power Plant’ published by AELB

Atmospheric trajectory analysis of cesium-137 from proposed nuclear power plant site in Bangka Island, Indonesia

Environmental risk assessment for nuclear power plant (NPP) operation is important to monitor the level of radionuclide concentration in the atmosphere and to determine the health risks associated with potential external radiation exposure. A NPP site was proposed in Bangka Island, Indonesia, 554 km from Johor Bahru, Malaysia. In the event of postulated nuclear emergency, the radionuclide dispersion from Bangka Island can possibly arrive in Malaysia’s atmosphere due to its close distance with Malaysian border. The purpose of this study is to assess the trajectories of Cs-137 radionuclide towards Malaysia from Bangka Island NPP site. A simulation was conducted using Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT) to describe the movement of radionuclides in the atmosphere from Bangka Island towards Malaysia. The result shows the trajectories and direction of both radionuclides are very much affected by the monsoon season, as well as the meteorological characteristics such as wind speed and direction. In the simulated event of radioactive release in 2019, the trajectories can be seen moving directly towards Malaysia in May, June, July, August, September and October. It is concluded that if Indonesia were to proceed with the NPP construction in Bangka Island, necessary preparation such as emergency plan and risks mitigation should be strategized early in Malaysia to safeguard the public and the environment

Malaysia energy strategy towards sustainability: A panoramic overview of the benefits and challenges

Sustainable energy supply is essential for actualizing Malaysia's vision to become a high-income country. The current power production and demand trends show that Malaysia has a reserve margin that will only last for the next few years. This calls for further investment, research and development in the country's power sector in order to meet the ever increasing energy demand. The government's diversification policy and power sector expansion plan emphasizes on the incorporation of renewable energy sources (RESs) and other less CO2 emitting sources like nuclear into the national energy mix. However, the environmental ramifications of this policy should be part of any future expansion plan of national grid. This paper presents a panoramic overview of the Malaysian energy sector, the energy policy revolution and the power sector expansion strategy towards secure sustainability. We want to bring into focus the benefits and challenges of Malaysia's power sector expansion plan with the aim of stimulating further discussion and research on the environmental ramifications of the plan
