[en] The nuclear technology has encouraged the world development and brought a number of benefits to society. These benefits occurred in important social sectors such as Agriculture, Industry, Health Sciences, Environmental Sciences and the production of energy. The research in the nuclear area is justified, accordingly, as an important factor for science development, technology and innovation. Despite the importance of nuclear energy, there is a collapse in the generation, transmission and sharing of nuclear knowledge. The threat of regression in this area is evidenced by the difficulty of generating new knowledge and practices regarding the maintenance of some critical areas. This project focuses its attention on studying, specifically, the lack of young engineers and technical professionals to replace the older, considered this, an alarming situation. Therefore, it is necessary to identify and record the key skills of experienced workers, through a set of tools to elicitation (capture) this knowledge, as expertise is mainly with people, and is lost when they leave the organization. Against, the Knowledge Management provides methodologies for the process of stimulating the creation, collection and knowledge dissemination process, in order to achieve strategic objectives. This study aims to contribute to the building of a model for the Brazilian nuclear knowledge preservation and, therefore, contributes to the maintenance and innovation of activities in this area.
