[en] Disposal is inevitable for sustainable radioactive waste management. In line with the 12th Malaysia Plan and the National Policy on Science, Technology and Innovation 2021-2030, application of science, technology and innovation is emphasized in providing solutions for socio-economic issues and national interests, where in this regards, the ultimate goal of radioactive waste management is to ensure safety and health of people and the environment is protected. The development of a disposal facility spans on a long time frame, and therefore calls for short, middle and long-term planning. Besides the technicality aspect, political, economic and social standing impose strong influences towards a successful implementation of a radioactive waste disposal project. In the past, Malaysia has had witnessed the struggle to balance these non-technical components. This paper looks into the past, present and future planning of a national repository facility in Malaysia and the key role of the Malaysian Nuclear Agency in this endeavor. (author)

[en] Improper management of radioactive waste will cause harm to people and the environment. Therefore this study is to evaluate parameters from selected criteria of site selection for radioactive waste repository through analysis and evaluation using Analytical Hierarchy Process or AHP. The AHP technique was used to evaluate parameters of a selected criteria because they are always difficult to prioritize their weighted values from expert judgement. This paper is to discuss the assessment or evaluation of Multi-criteria Decision Analysis (MCDA) for selecting the radioactive waste repository facilities. There are many methods to be used in various countries in determining weighted values for different aspects, criteria, and parameters for selecting the suitable sites of radioactive waste repository facility. The weighted values can be distinguished based on countries, especially in the geographical and socio-economic aspects of the specific country. Among the popular MCDA methods used by researchers is the Analytical Hierarchy Process (AHP) to obtain weighted values of parameters in order to determine the best solution for site selection of radioactive waste repository quantitatively. In general, there are five main steps for AHP analysis, namely the problem modelling process in hierarchical form, paired comparison matrix, the process of obtaining relative weights for each parameter, determination of consistency ratios and sensitivity analysis. Resulting from this analysis shows that weighted values of parameters of selected criterion have been determined accordingly. (author)
