1. Implementation and qualification of neutronic calculation methodology in subcritical reactors driven by external neutron sources and applications / Implementação e qualificação de metodologia de cálculos neutrônicos em reatores subcríticos acionados por fontes externa de nêutrons e aplicações
This works had as goal to investigate calculational methodologies on subcritical source driven reactor, such as Accelerator Driven Subcritical Reactor (ADSR) and Fusion Driven Subcritical Reactor (FDSR). Intense R&D has been done about these subcritical concepts, mainly due to Minor Actinides(MA) and Long Lived Fission Products(LLFP) transmutation possibilit

2. Reações nucleares de alta energia (" Spallation") e sua aplicação em cálculo de sistemas nucleares acionados por Fonte / High energy nuclear reactions ("Spallation") and their application in calculation of the acceleration driven systems (ADS)
Neste trabalho apresentamos um estudo das reações nucleares de alta energia que são fundamentais na definição do termo fonte dos reatores nucleares subcríticos acionados por fonte externa. Estas reações nucleares, também conhecidas como "spallation", consistem na interação de hádrons de alta energia com os núcleons do núcleo atômico. A fenomen

3. Neutron production evaluation from a ADS target utilizing the MCNPX 2.6.0 code
Accelerators Driven Systems (ADS) are an innovative type of nuclear system, which is useful for long-lived fission product transmutation and fuel regeneration. The ADS consist of a coupling of a sub-critical nuclear core reactor and a proton beam produced by particle accelerator. These particles are injected into a target for the neutrons production by spall

4. The utilization of crisp code in hybrid reactor studies
One of the main applications of the Hybrid Reactors (ADS - Accelerator Driven System) is the incineration of transuranics (TRU) by fast neutrons that emerge from a spallation source in a sub critical reactor waste burner [1, 2]. For this application, an accurate description and prediction of spallation reaction is necessary, including all the characteristics

6. Developement of crisp package for spallation reaction studies and its utilization in ADS (Accelerator Driven System)
The progress of nuclear physics had allowed a better understanding of nuclear structure and reaction mechanisms, but also enables important applications of nuclear energy in our modern way of life. We can point out those ones related to power generation from nuclear reactors, providing an almost inexhaustive power source due to the huge quantities of nuclear
