This invention belongs to the field of microbial application technology, specifically relating to a method for preparing fermented *Lactobacillus limnoxicamis* extracellular vesicles, the product, and its applications, particularly the application of these fermented *Lactobacillus limnoxicamis* extracellular vesicles and their lyophilized formulations in the preparation of products with antioxidant or anti-aging effects. In this invention, *Lactobacillus limnoxicamis* is inoculated into a modified extracellular vesicle induction medium for fermentation. After culture, a two-stage solid-liquid separation is performed, and the supernatant is collected to obtain the extracellular vesicle processing solution. This solution is purified using a capillary electrophoresis system, and the positive extreme liquid is collected and filtered to obtain the purified product of fermented *Lactobacillus limnoxicamis* extracellular vesicles. The extracellular vesicles derived from fermented *Lactobacillus limnoxicamis* prepared by this invention can effectively scavenge free radicals. Somatic cell experiments have demonstrated its excellent anti-aging properties, and the transformation and application research of *Lactobacillus* extracellular vesicles has explored its development potential in the field of anti-aging products.

The utility model relates to a nuclear power station heat pipe type passive containment heat export system. At present, an existing passive containment heat export system is complex in arrangement, and a water tank and other equipment need to be maintained for a long time. The nuclear power station heat pipe type passive containment heat export system comprises a containment (9), and a demineralized water make-up pump (1), a water make-up pipeline (2), a containment inner heat pipe absorption section (3), a heat pipe mother pipe electric stop valve (4), a heat pipe vacuumizing pipeline (7) and a heat pipe vacuumizing pump (8) are installed in the containment. The water replenishing pipeline and the heat pipe vacuumizing pipeline are respectively connected with a heat pipe cooling section mother pipe (5); the heat pipe cooling section mother pipe is provided with a heat pipe mother pipe electric stop valve, one end of the heat pipe cooling section mother pipe is connected with a group of containment inner heat pipe absorption sections, and the other end of the heat pipe cooling section mother pipe is connected with a containment outer heat pipe absorption section (6). The utility model is applied to the field of passive containment heat export systems.
