The cladding of fast reactor fuel rods, made of stainless steel, presents significant challenges in cutting due to its ductility, which leads to increased tool wear and poor cut quality with traditional mechanical methods. Laser cutting has emerged as a superior alternative, offering non-contact precision, high efficiency, and suitability for radioactive environments. This study systematically investigates the effects of laser cutting parameters—cutting speed, focal position, power, and gas pressure—on the cutting quality of simulated fast reactor fuel rods. The results show that optimal cutting is achieved with a cutting speed of 1 m/min, a focal position between − 20 and − 25 mm, a laser power between 7200 and 9600 W, and a gas pressure of 10 MPa. These parameters provide the best balance between cutting efficiency, surface roughness, and minimal slag formation. This study contributes valuable insights into optimizing laser cutting technology for nuclear fuel rod processing, with potential applications in fuel reprocessing and decommissioning.

1. IntroductionWith the urgent need to accommodate a high proportion of distributed renewable energy integration, it is essential to enhance the capacity and reliability of active distribution networks (ADN) from both spatial and temporal dimensions [1]. Current distribution systems face challenges such as weak grid structures, uneven local load distribution, and inadequate power supply capabilities.

Los síntomas depresivos, el deterioro funcional y la disminución de la calidad de vida (CV) son tres dominios importantes del trastorno depresivo mayor (TDM). Sin embargo, la posible relación causal entre estos factores aún no se ha dilucidado. Además, no se sabe si ciertos síntomas del TDM son más perjudiciales que otros. El enfoque de red es una solución prometedora a estas deficiencias.
