Parametric effects and rate-limiting mechanism analysis of tritium extraction process in permeator against vacuum

Achieving high-efficiency tritium extraction represents a significant engineering challenge in the context of liquid breeder blanket concepts. The present paper focuses on the permeator against vacuum technology, establishing three-dimensional transport models and one-dimensional...

Microstructural Evolution and Through‐Thickness Mechanical Property Gradients in a 70‐mm‐Thick 316LN Stainless Steel Joint Produced by Narrow‐Gap Laser Welding With Pre‐Placed Filler Plates

Reliable joining of 70‐mm‐thick 316LN stainless steel is essential for fusion reactor applications. A high‐efficiency narrow‐gap laser welding strategy combining beam oscillation with pre‐placed filler plates was developed. A sound joint was produced in five passes, including one...
