The 21st century brought remarkable technological advances in relation to sources of electricity generation called sustainable. However, clean energy sources have disadvantages, such as high implantation costs and low power generated, when compared to the nucleoelectric matrix. Regarding safety, the nucleoelectric technology works with modern and efficient methodologies, in which the Probabilistic Safety Assessment (PSA) stands out. This paper presents the main steps to perform PSA, in addition to showing the best practices found in countries such as the United States, France, Canada and the United Kingdom compared to Brazil.
