Description

technical field [0001] The invention relates to the field of energy technology, in particular to a method for realizing coupled calculation of tritium transport models in different dimensions based on Matlab / Simulink. Background technique [0002] Nuclear fusion energy is one of the most important ways to solve human energy problems. Tritium is an important fuel used in fusion reactors, yet it hardly exists in nature. In order to ensure the full utilization of the precious fusion fuel deuterium and tritium, the fusion reactor is designed with a large-scale tritium factory to realize the rapid recovery and recycling of unburned deuterium-tritium fuel and bred tritium. On the other hand, tritium is radioactive and permeable, and it is very easy to penetrate and retain through the materials of the fuel cycle system and related components, resulting in the loss of tritium fuel and potential radioactive hazards; Personnel cause potential safety hazards and unnecessary losses. ...
