Abstract:
The LBB（leak-before-break） technology has been obtained extensive application in designing the high power lines in nuclear power plants since early 1970s.It plays an important role in simplifying the design of nuclear power plants,making them less expensive,convenient for in-service inspection and decreasing the total radioactive exposure.The background and current status is reviewed,and the processes to apply the LBB technology are summarized.Suggestion on the future research is presented.
