Continuous monitoring of thermal balance for power level determination of IEAR-1 reactor

This research deals with thermal balance calculation for real time power level determination of IEA-R1 nuclear research reactor. It is also shown the development of a supervision software (Visual Basic) of operation parameters. The assembled data acquisition system allows data analysis during reactor operating, giving a reliable measurement of reactor power, and the organization of a data base allows a back-up surveillance of reactor operation whenever necessary. Results obtained from temperature and primary flow are shown in a continuous form and also the Data Base implementation for further studies and analysis of energy balance behavior of the many reactor components. Besides it is planned to manage N-16 activity measurement channel (monitoring) for comparison of acquired data results for thermal calculations. (author)
