Artigo IPEN-doc 23505 Cutting techniques for facilities dismantling in decommissioning projects2016 - LAINETTI, PAULO E.O.Fuel cycle related activities were accomplished in IPEN-CNEN/SP in laboratory and pilot plant scale and most facilities were built in the 70-80 years. Nevertheless, radical changes of the Brazilian nuclear policy in the beginning of 90’s determined the interruption of several fuel cycle activities and facilities shutdown. Some laboratory and pilot plant decommissioning activities have been performed in IPEN in the last years. During the operational activities in the decommissioning of old nuclear fuel cycle facilities, the personnel involved in the task had to face several problems. In old facilities, the need of large components dismantling and material removal use to present some difficulties, such as lack of available and near electricity supply. Besides this, the spread out of the superficial contamination in the form of dust or aerosols and the exposure of workers should be as much as possible avoided. Then, the selection and availability of suitable tools for the task, mainly those employed for cutting and segmentation of different materials is of significant importance. Slight hand tools, mainly those powered by rechargeable batteries, facilitate the work, especially in areas where the access is difficult. Based on the experience in the dismantling of some old nuclear facilities of IPEN-CNEN/SP, some tools that would have facilitated the operations were identified and their availability could have improved the quality and efficiency of different individual tasks. In this paper, different cutting problems and techniques, as well as some available commercial hand tools, are presented as suggestion for future activities.Capítulo IPEN-doc 13901 Decommissioning of nuclear fuel cycle facilities in the IPEN-CNEN/SP2008 - LAINETTI, P.E. de O.; FREITAS, A.A. de; MINDRISZ, A.C.; CAMILO, R.L.Artigo IPEN-doc 13964 Decommissioning of nuclear fuel cycle facilities in the IPEN-CNEN/SP2007 - LAINETTI, P.E.O.Artigo IPEN-doc 13603 Artigo IPEN-doc 13602 Artigo IPEN-doc 13601 Desmantelamento e descomissionamento de instalacoes nucleares no Brasil2008 - LAINETTI, P.E. de O.Artigo IPEN-doc 15590 Molten Salts as stripping media for radioactive superficial decontamination2010 - LAINETTI, PAULO E. de O.Artigo IPEN-doc 10730 Decommissioning of nucler fuel cycle facilities - IPEN's experience2005 - LAINETTI, P.E.O.Artigo IPEN-doc 12163 Reintegration of areas of the IPEN´S dismantled nuclear fuel cycle pilot plants as new laboratories of the CQMA2007 - LAINETTI, PAULO E.O.; COTRIM, MARYCEL E.B.; VASQUES, FRANCISCO M.F.; FERREIRA, ROBSON de J.; PIRES, MARIA A.F.Artigo IPEN-doc 17120 Cutting techniques for facilities dismantling in decommissioning projects2011 - LAINETTI, PAULO E.O.
