Abstract

Abstract

Analysis on fuel assembly design, manufacture, operation and post irradiation examination are performed, and the improvement of current safe operating insurance is proposed. In particular, the proposal of strengthen disassembly inspection, pool side inspection and hot cell analysis of fuel assembly is put forward. Suggestions are also proposed for the fuel assembly development on self-reliance, including preventing abrasion at lower part of the fuel rod, improving the design of anti-debris and strengthening the strength of the component structure.
