NON-DESTRUCTIVE TESTING OF FUEL ELEMENTS FOR NUCLEAR REACTORS

摘要

It is possible to mark out two scopes of non-destructive testing which are most important and specific to nuclear power. The testing of nuclear fuel elements (NFE) and nuclear fuel assemblies (NFA) in process of their production; Material engineering researches of NFE and NFA before and after their using in reactor. Significant growth of NFE and NFA production and increase of their quality requirements raises the necessity of development the new devices generation for non-destructive testing during production process, and examination after using them in reactor facility. In creation of such devices and monitoring systems and their use there were take part as the specialized enterprises, engaged in development of the equipment, and the enterprises manufacturing NFE and NFA. For monitoring of various parameters there have been used a wide spectrum of the methods based on various physical principles: radiation methods, a method of eddy currents, optical methods, etc.
