“…If a greater electrical conductivity is available, then a greater processing capacity of the mentioned components is achieved. The considerable increase in the use of computers and mobile phones further explains the great interest of the electronic industry in the use of nuclear research reactors [5]. Furthermore, research and teaching of nuclear technology have also grown in recent decades [6].…”

The demand for nuclear fuel for research reactors is increasing worldwide. However, some nuclear fuel factories have small production volumes. There is a gap in the literature regarding how to expand capacity of those facilities in a safe and reliable way. Thus, the purpose of this work is to propose and validate a conceptual model to increase the production capacity of these factories. We addressed factories that produce plate-type fuel elements loaded with LEU U3Si2-Al, which are typically used in nuclear research reactors. We collected data from a real nuclear fuel plant and applied the model to that data, i.e., we set up a case study. We developed two different strategies for the use of the model, thus generating several production scenarios. Each scenario is an experiment of the different possibilities to enlarge the capacity. We applied discrete events simulation in order to cover all production scenarios. Our tests indicated significant increases in productive capacity, thus showing that the model has fully achieved its proposed objective. One of the main conclusions that we point out is the model’s effectiveness. That effectiveness was demonstrated by using the model in two different strategies and obtaining increases in capacity with both of them.

“…12 For instance, an amorphous-to-crystalline shell-core structure forms under neutron irradiation, becoming a kind of amorphous and crystalline (AAC) composite structure. 13 SiC experiences crystalline-toamorphous transformation by uniaxial compression, 14 low energy ions, 15 scratching, 12 nano-cutting, 16 laser ablation driven shock compression, 10 ion irradiation, 17 and pressure and shear in a rotational diamond anvil cell, 18 forming an AAC composite structure. After electrical discharge machining on a SiC surface, a re-solidified layer is produced, consisting of polycrystalline SiC, a graphite layer, amorphous Si, carbon (C) and nanocrystalline SiC, forming an AAC structure.…”

“…31,32 However, the self-healing occurred on pure crystalline or amorphous fractured surfaces, resulting in applications that are limited dramatically under the two extreme conditions. For example, SiC undergoes phase transformation under deformation, stress and ion irradiation, [13][14][15][16][17][18] forming an AAC composite structure. Therefore, the AAC composite structure is a usual state of SiC under working conditions.…”

The demand for nuclear fuel for research reactors is rising worldwide. Thus, the production facilities of this kind of fuel need reliable guidance on how to augment their production in order to meet the increasing demand efficiently and safely. We proposed a specific procedure for increasing production capacity. That procedure was tested with data from a real plant, which produces plate-type fuel elements loaded with LEU U 3 Si 2 -Al fuel. The test was made by means of discrete event simulation, and the results indicated the proposed procedure is efficient in raising production capacity.
