Abstract: The small branch pipes of nuclear power plants at home and abroad during operation arise many kinds of failures,
such as wall thinning, leak, fatigue fracture. And these failures have passive effects on safety and economic efficiency of nuclear
power plant. Based on the analysis of the main kind of defects of small branch pipes and weakness in supervision and management,
this paper proposed new inspection methods to optimize the current methods. At last, it systematically illustrated the supervision
and management method of the small branch pipes.

Key words: nuclear power plant; small branch pipes; supervision and management; inspection
