    Digital systems implemented at the IPEN nuclear research reactor (IEA-R1)
    2013 - CARDENAS, JOSE P.N.; MADI FILHO, TUFIC; RICCI FILHO, WALTER; CARVALHO, MARCOS R. de; BENEVENUTI, ERION de L.; GOMES NETO, JOSE
    IPEN (Nuclear and Energy Research Institute) was founded in 1956 with the main purpose of doing research and development in the field of nuclear energy and its applications. It is located at the campus of University of Sao Paulo (USP), in the city of Sao Paulo, in an area of nearly 500,000 m2. It has over 1.000 employees and 40% of them have qualification at master or doctor level The institute is recognized as a national leader institution in research and development (R&D) in the areas of radiopharmaceuticals, industrial applications of radiation, basic nuclear research, nuclear reactor operation and nuclear applications, materials science and technology, laser technology and applications. Along with the R&D, it has a strong educational activity, having a graduate program in Nuclear Technology, in association with the University of Sao Paulo, ranked as the best university in the country. The Federal Government Evaluation institution CAPES, granted to this course grade 6, considering it a program of Excellence. This program started at 1976 and has awarded 458 Ph.D. degrees and 937 master degrees since them. The actual graduate enrollment is around 400 students. One of major nuclear installation at IPEN is the IEA-R1 research reactor; it is the only Brazilian research reactor with substantial power level suitable for its utilization in researches concerning physics, chemistry, biology and engineering as well as for producing some useful radioisotopes for medical and other applications. IEA-R1 reactor is a swimming pool type reactor moderated and cooled by light water and uses graphite and beryllium as reflectors. The first criticality was achieved on September 16, 1957. The reactor is currently operating at 4.5 MW power level with an operational schedule of continuous 64 hours a week. In 1996 a Modernization Program was started to establish recommendations in order to mitigate equipment and structures ageing effects in the reactor components, detect and evaluate obsolescence of some electrical and electronic systems. In this work we will show a retrospective and results of digital systems applied to IEA-R1 reactor concerning electronic equipments and systems refurbishment and modernization and the necessity of a new control console implementation.

    Falcao - a relational database to storaging the variables monitored in the research reactor IEA-R1
    2007 - ANDRADE, DELVONEI A. de; NETO, JOSE G.
    The objective of this work is to introduce all initial steps for the creation of a relational database, named FALCAO, to support the storaging of the monitored variables in the IEA-R1 research reactor, located in the Instituto de Pesquisas Energéticas e Nucleares, IPEN – CNEN/SP. As introduction, it is considered the modeling importance of the logic diagram and its direct influence in the integrity of the provided information. It is presented the concepts and steps of normalization and denormalization including the entities and relations involved in the logical model. It is also presented the effects of the model rules in the acquisition, loading and availability of the final information, under the performance concept, since the acquisition process, loads and provides lots of information in small intervals of time. The data logical model, considering the desired performance and the sharing information is also presented.

    Modelo híbrido de banco de dados relacional, de alto desempenho e capacidade de armazenamento, para aplicacoes voltadas a engenharia nuclear
    2008 - GOMES NETO, JOSE
    O objetivo deste trabalho é apresentar o banco de dados relacional, denominado FALCAO, que foi criado e implementado com a função de armazenar as variáveis monitoradas no reator de pesquisa IEA-R1, localizado no Instituto de Pesquisas Energéticas e Nucleares, IPEN CNEN/SP. O modelo lógico de dados e sua influência direta na integridade da informação fornecida são cuidadosamente considerados. São apresentados os conceitos e etapas de normalização e desnormalização, incluindo as entidades e relacionamentos do modelo lógico de dados. São também apresentadas as influências dos relacionamentos e regras do modelo de dados nos processos de aquisição, carga e disponibilização da informação final, sob a óptica do desempenho, visto que estes processos ocorrem em lotes e em pequenos intervalos de tempo. A aplicação SACD, através de suas funcionalidades, apresenta as informações armazenadas no banco FALCAO de maneira prática e otimizada. A implementação do banco de dados FALCAO ocorreu com o êxito esperado, mostrando-se indispensável ao cotidiano dos pesquisadores envolvidos por conta da substancial melhoria dos processos e da confiabilidade associada a estes.
