RESUMO

The IPR-R1 TRIGA Mark I nuclear research reactor, at the Nuclear Technology Development Center (CDTN), is a pool type reactor cooling by light water. TRIGA reactors (Training, Research, Isotope, General Atomics) were designed for research, training and radioisotope production. The International Atomic Energy Agency (IAEA) recommends the use of safety and friendly interfaces for monitoring and controlling the operational parameters of the nuclear reactors. In this context, a system to simulate the neutron evolution flux of the TRIGA IPR-R1 reactor (TRIGA Simulator System - Sistema Simulador TRIGA) was developed using the LabVIEW software, considering the modern concept of virtual instruments (VIs) using electronic processor and visual interface in video monitor, with the objective of assisting the reactor operator training, allowing to study, to observe, and to analyze the behavior, and the tendency of some processes occurring in the reactor. Consequently the reactor operation parameters can be simulated and their relations can be visualized, supporting on the understanding of the interrelation of these parameters and their behavior, promoting a better knowledge of TRIGA IPR-R1 reactor processes. Some scenarios are presented to demonstrate that it is possible to use predetermined values in any parameters to verify its effect in the other ones. Therefore the TRIGA Simulator System (Sistema Simulador TRIGA) will allow the study of parameters, which affect the reactor operation, without the necessity of using the facility, avoiding risk, and reducing costs and operation time.
