This propose to walk around about the nuclear programs of Brazil and Mexico from a comparative perspective. Likewise, we will make an analysis of the situation abroad, in order to get closer to the main objective of this investigation, the protests and civil associations that emerged in the mid-1960s around the world and in the region to be studied in 1970, having their development in 1980 to 1990.
We selected these two countries of Latin-American because both began their nuclear programs in the mid-1950s, within the framework of the Atoms for Peace program promoted by the United States. However, their projects had a different development and scope throughout the study period.
For example, in 1960s, both countries experienced relative periods of economic and sociopolitical stability, and their nuclear programs achieved further development. However, in 1970s, the nuclear programs of Brazil and Mexico had visible delay problems, as a result of economic crises in both cases and political instabilities in the Brazilian case.
Finally, our study ends in the 1980s and early 1990s, years in which both countries abandoned the nuclear option as a primary alternative to achieve energy self-sufficiency.

The objective of this presentation is to present and analyze the project created by the National Nuclear Energy Commission (CNEN) to install uranium benefit plants in the state of Sonora, Mexico. Among the tasks that the commission had to carry out was to exploit uranium in the country. The first explorations showed that important economically exploitable uranium deposits were found in Sonora. For this reason, it was considered advisable to install benefit plants with the intention of separating the fissile materials from the extracted minerals. This involved using local and imported technology to begin this work. The project consisted of testing which would be the most appropriate method, as well as the necessary instruments in order to calculate the cost of processing uranium that would be used in future reactors installed in the national territory. At the same time, they wanted to know what human resources would be necessary to carry out the projected task. The CNEN considered that it was necessary to take this step in the industry to achieve the goal of producing nuclear energy that would satisfy national demand. In 1963, a first processing plant was installed at the University of Sonora for experimental purposes, the results of which would allow the project to be carried out on a large scale in the future. We will end by presenting the results and the destination of this research with the processing plant in Sonora.

Within a research protocol, the literature review has the function of providing background information related to the topic that is intended to be addressed. Likewise, the discussion of said research requires literature that provides meaning to the findings, that explains and supports them, indicating how they support the affirmation or rejection of a hypothesis, if it has been raised. In this sense, it is common for scientific researchers, both students in training and a large part of already accomplished researchers, to limit their searches to articles, books and other scientific material, leaving aside other types of material that could provide substantial information to their research, as is the case of historical material, which can not only provide data on the permanence or disappearance of species of flora and fauna, but also provides historical background on the relationship of the inhabitants with their surrounding ecological environment. Thus, this paper proposes to show, based on a Jesuit missionary chronicle, the potential that said historical material provides for future research.
