PCRELAP5 - Programa de cálculo para os dados de entrada do código RELAP5

Após os acidentes nucleares ocorridos no mundo, critérios e requisitos extremamente rígidos para a operação das instalações nucleares foram determinados pelos órgãos internacionais que regulam essas instalações. A partir da ocorrência destes eventos, as operadoras de plantas nucleares necessitam simular alguns acidentes e transientes, por meio de programas computacionais específicos, para obter a licença de operação de uma planta nuclear. Com base neste cenário, algumas ferramentas computacionais sofisticadas têm sido utilizadas como o Reactor Excursion and Leak Analysis Program (RELAP5), que é o código mais utilizado para a análise de acidentes e transientes termo-hidráulicos em reatores nucleares no Brasil e no mundo. Uma das maiores dificuldades na simulação usando o código RELAP5 é a quantidade de informações geométricas da planta necessárias para a análise de acidentes e transientes termo-hidráulicos. Para a preparação de seus dados de entrada é necessário um grande número de operações matemáticas para calcular a geometria dos componentes. Assim, a fim de realizar estes cálculos e preparar dados de entrada para o RELAP5, um pré-processador matemático amigável foi desenvolvido, neste trabalho. O Visual Basic for Applications (VBA), combinado com o Microsoft Excel, foi utilizado e demonstrou ser um instrumento eficiente para executar uma série de tarefas no desenvolvimento desse pré-processador. A fim de atender as necessidades dos usuários do RELAP5, foi desenvolvido o Programa de Cálculo do RELAP5 PCRELAP5 onde foram codificados todos os componentes que constituem o código, neste caso, todos os cartões de entrada inclusive os opcionais de cada um deles foram programados. Adicionalmente, uma versão em inglês foi criada para PCRELAP5. Também um design amigável do PCRELAP5 foi desenvolvido com a finalidade de minimizar o tempo de preparação dos dados de entrada e diminuir os erros cometidos pelos usuários do código RELAP5. Nesse trabalho, a versão final desse pré-processador foi aplicada com sucesso para o Sistema de Injeção de Emergência (SIE) da usina Angra 2.

Do arquivo ao novo : impactos da tecnologia digital no armazenamento e disseminação da informação na cultura contemporânea

While taking paths from the archive to the new, this dissertation reflects on the resulting impacts of the introduction, massification and dissemination of digital technology, in the way we store and deal with information, inside the complex that we understand as culture. To this end, a theoretical investigation is performed in order to build a conceptual body from which concepts are drawn in order to effectuate a practical research. The theoretical research starts with an exordium in which the concept of the archive is deconstructed in order to identify it as a device of power and to analyse its transition from a technical analog object into a digital technology. Following this, a historical context is established, drawing on the evolution of power exercises and apparatuses, and a reading of the impacts of the present technological mediation on experience, knowledge cons¬truction and forms of control is developed. Finally, some hypotheses on the evolution of technology are formulated. The practical research materializes in the form of a digital platform which takes place in two moments: one of archive, the other of program. The first moment, of archive, con¬sists of a repository of projects dealing with the dissertation’s subject. The second moment, of program, is configured as a cultural program implemented through computer programs. These, in their execution, result in performances which, taking from the information col¬lected on the archive generate a new experience of that same information. To this effect, a framework was structured in order to have computational processes systematized in a way that the performances result in experiences with a potential for novelty, expression and reflection. Both theoretical and practical components of the research seek to address digital technology not as an end in itself, but as a factor that affects human experience and behaviour
