Tinjauan Inventori Daur Hidup dalam Pengelolaan Mineral Ikutan Radioaktif

Abstract

Naturally-Occurring Radioactive Material (NORM) is generated by several non-nuclear activities or events. Life cycle assessment can be used to evaluate the steps and processes in managing NORM. However, the use of life cycle assessment for NORM is still limited. This paper aims to identify the key considerations when conducting a life cycle inventory analysis for NORM management. The life cycle assessment process includes determining objectives and scope, performing a life cycle inventory analysis, impact assessment, and interpretation. Since NORM is produced by a wide range of activities, it is essential to establish clear objectives and scope from the outset. Analysis of NORM management inventories will vary depending on the physical, chemical, or radionuclide characteristics of the NORM. One of the main challenges in inventory analysis is collecting data and information related to the input, process, and output of a processing unit based on the objectives and scope. Some general considerations that can be used in inventory analysis include determining flow and mass diagrams, location, and equipment data. Flow and mass diagrams show the input, process, and output stages of a processing unit, while location data can be used as a constraint in the life cycle assessment system. Equipment data will contain information regarding the type and number of equipment, equipment performance details, energy requirements, fuel requirements, etc. Inventory analysis can only be carried out accurately and effectively when the objectives and scope of the NORM management life cycle assessment are known. However, even if the processing unit and NORM management characteristics influence the input and output information and data, initial information regarding energy and fuel sources can still be analyzed.
