| contents | Establishment of cementation parameters of dried waste from evaporation coming from NPP operation Érica Rodrigues de Faria Clédola Cássia Oliveira de Tello Bruna Silveira Costa Biología Waste repository cementation dried process acceptance criteria The radioactive wastes generated in Brazil are treated and sent to initial and intermediate storages. The “Project RBMN” proposes the implantation of the Brazilian repository to receive and permanently dispose the low and intermediate level radioactive wastes. The evaporator concentrate (EC) is one of liquid wastes generated in a Nuclear Power Plant operation and usually it is cemented directly inside the packing. The aim of this work was to increase the amount of the incorporated waste in each package, using the drying process before the cementation, consequently reducing the volume of the disposed waste. Drying and cementation parameters were established, aiming to obtain cemented waste products that comply with the requirements of Brazilian standard “Acceptance Criteria for Disposal of Low and Intermediate Radioactive Wastes (LIRW)”. The evaporator concentrate (EC) was dried in lab oven and the dried EC was cemented, varying the amount of cement, dry waste and water. In the preliminary studies, it was incorporated 5% of dried EC in the product, using water/cement ratio of 0.27. This result suggests the possibility of continuing the research to improve the EC incorporation. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280838021 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.2A Vol.7 |
