Current regulatory framework for radioactive waste management in Brazil
2023 - ANDRADE, MONISE; ALVES, ITALO H.; VICENTE, ROBERTO
Radioactive waste is classified according to different criteria. In Brazil, the stages of radioactive waste management for each category are established on the classification of waste, so the structure of responsibilities varies depending on the type. Therefore, the chain of responsibility should be easily visible for all stakeholders. However, it is often distributed in different documents and hierarchy levels of the legal and regulatory framework. This work proposes to carry out a synthesis of the classification and the management of radioactive waste, using visual resources, for a better understanding of this regulatory scenario.
Regulations for the disposal of disused sealed radioactive sources in Brazil
2023 - ANDRADE, MONISE; VICENTE, ROBERTO
Radioactive waste laws in Brazil were designed according to the volume of radioactive waste produced. However, the laws and regulations do not classify nor provide guidance on the disposal of disused sealed radioactive sources (DSRS), a special category of radioactive waste due to its particularities with high potential for damage. Therefore, this work aims to propose specific regulations for disposing DSRS, which is essential for the continuity of radioactive waste disposal, since the current regulations do not offer the most adequate treatment for DSRS, in addition to being completely out of step with disposal in practice.
Proposta de regulação específica para deposição de fontes radioativas seladas em desuso
2023 - ANDRADE, MONISE V. de
A legislação e a regulação vigentes no Brasil para gestão de rejeitos radioativos são lacônicas sobre a deposição de fontes radioativas seladas em desuso (FRSD). Essas fontes apresentam grande potencial de causar acidentes radiológicos devido a seu pequeno tamanho (a maioria possui entre três e cinco centímetros) e a seus altos níveis de radioatividade. Para que se possa continuar a desfrutar dos benefícios que as fontes radioativas seladas proporcionam à sociedade, é preciso dispensá-las sem perigo ou risco de acidente. A Agência Internacional de Energia Atômica (IAEA) recomenda a deposição de FRSD em poço tubular profundo. Portanto, faz-se necessário discorrer sobre aspectos relevantes a serem incluídos em uma futura regulamentação da área da gestão de rejeitos radioativos, de modo que a deposição das FRSD seja realizada de acordo com a tecnologia recomendada e sob um arcabouço legal e regulatório adequado.
Precautionary and preventive measures in Brazilian law applied to radioactive waste management
2022 - ANDRADE, M.V.; VICENTE, R.
Nuclear technologies and radiation have offered technological and scientific growth nowadays, but there is a frequent paradox in this. While these technologies substantially increase the quality of human life, they also produce radioactive waste, which, when not properly managed, can generate risks that threaten to harm the environment and health. As a result, in risk management of radioactive waste, decision-making processes need to be guided by a framework of principles, including the precautionary and preventive principles. For this reason, the present work proposes to develop a legal analysis on radioactive waste risk management using the principles of precaution and prevention. These principles have similarities, but it is the differences in their structure that deserve to be highlighted, which is discussed and exemplified throughout this work. Furthermore, national and international experience in environmental damage has taught us that an identification and assessment of risk is necessary, because if preventive measures are not taken radioactive waste can be dispersed and harm the environment. When it comes to assessing the risk of radioactive waste, one of the precautionary measures is the application of a conservative stance in modelling scenarios, as there are still uncertain risks. Therefore, comprehending the different circumstances surrounding precautionary and preventive measures and having effective information about risk is essential for successful risk management.
