RESUMO

This work presents the Physics of Source Driven Systems (ADS). It shows some statics and kinetics parameters of the reactor Physics and when it is sub critical, that are important in evaluation and definition of these systems. The objective is to demonstrate that there are differences in parameters when the reactor is critical. Moreover, the work shows the differences observed in the parameters for different calculation models. Two calculation methodologies are shown in this dissertation: Gandini&Salvatores and Dulla, and some parameters are calculated. The ANISN deterministic transport code is used in calculation in order to compare these parameters. In a sub critical configuration of IPEN/MB-01 Reactor driven by an external source some parameters are calculated. The conclusions about calculation realized are presented in end of work.
