This research focuses on a detailed analysis of the operation and modeling of the core of a prototype nuclear microreactor with characteristics similar to Westinghouse’s eVinci nuclear microreactor. To achieve this, firstly, the RootT M software is employed to adapt the energy spectrum under which the 241Am-Be source operates. Secondly, the Geant4TM simulation tool is used, where, starting from the configuration of a cylinder embedded in a box, the unit cell is established to obtain a trapezoidal geometry as a geometric component of the hexagonal core of the microreactor. Additionally, the
essential parameters of the functions enabling the reproduction of data from a 241Am-Be source are presented in the results, playing a crucial role in initiating nuclear fissions in the uranium dioxide UO2 fuel rods. Finally, the appropriate dimensions of the various components of the core are established, including the fuel rods, neutron moderators, and control drums located within the microreactor.

Esta investigación se centra en un análisis detallado del funcionamiento y modelado del núcleo de un prototipo de microreactor nuclear con características similares al microreactor nuclear eVinci de Westinghouse. Para lograrlo, en primer lugar, se utiliza el software Root_TM para adaptar el espectro de energía bajo el cual opera la fuente de 241Am-Be. En segundo lugar, se emplea la herramienta de simulación Geant4_TM, donde, partiendo de la configuración de un cilindro incrustado en una caja, se establece la celda unidad para obtener una geometría trapezoidal como componente geométrico del núcleo hexagonal del microreactor. Además, en los resultados se presentan los parámetros esenciales de las funciones que posibilitan la reproducción de los datos provenientes de una fuente de 241Am-Be, desempeñando un papel crucial en el inicio de las fisiones nucleares en las barras de combustible de dióxido de uranio UO_2. Por último, se establecen las dimensiones apropiadas de las distintas componentes del núcleo, incluyendo las barras de combustible, los moderadores neutrónicos y los tambores de control localizados en el microreactor.
