Topical aspects of non-destructive testing (NDT) of equipment and pipelines of power units of nuclear power plants (NPP) are considered. Non-destructive testing is an integral part of the entire life cycle of a nuclear power plant. Briefly analyzed documentation and types of non-destructive testing at the stage of manufacturing equipment and pipelines. Power of ultrasonic testing of welded joints of pipelines with a thickness of 2 to 6 mm. The main points of drawing up technological maps of non-destructive testing are noted. A brief analysis of the application of non-destructive testing in accordance with the requirements of the regulatory documents of the Russian Federation and the safety standards of the International Atomic Energy Agency is provided. It is shown that in recent years there has been a tendency to expand the role of NDTs from the classical approach of detecting and assessing defects to the use of NDTs in the study of metal degradation and ageing processes during the operation of NPP equipment and pipelines.

The paper presents some approaches and methods for assessing and evaluation of different properties of equipment and pipelines metal of nuclear power plants during an operation such as a stress-strain state, a temperature and electrochemical effects. A problem statement for ageing management is considered for such metal properties of the heat – bearing agents. For this purpose, an observation of literature is provided for non – destructive testing (NDT) methods that have a correlation to a degradation factor defined by certain properties. There is has been made a case to apply NDT methods as a promising tool for an estimation and evaluation of degradation factor for a metal of potentially hazardous equipment. For this purpose there are proposed some rational and efficient solutions likes of acoustic methods based on structural – reverberation noise analysis, electromagnetic methods based on a coercive field strength deviation and electrical methods based on principles of potentiometry.

An analytical review of the safety standards of the International Atomic Energy Agency (IAEA) and documents of the Russian Federation in the field of nuclear power plant resource management is presented. The importance of non-destructive testing in the aging control system of structures, systems and elements of nuclear power plants is shown. The problems of aging management are noted, which can be solved with the help of non-destructive testing. A systematic approach to ensuring safety at all life stages of nuclear power plants is noted: design, construction, production (manufacturing), installation, operation (including extension of the period), reconstruction and decommissioning.

A set of new regulatory rules on nuclear power plants have been implemented in Japan effective October 1, 2003, in order to conduct the Inservice Inspection (ISI) effectively and to examine fitness-for-service properly. The new regulation utilizes the Japan Society of Mechanical Engineer (JSME) Codes on fitness-for-service for nuclear power plants. The rules are applied for the ISIs and for evaluation of structural integrity of the class 1 components and the core shrouds with flaws. Additional components will be subjected to the structural integrity examination, in accordance with the further development of the codes and with establishment of the performance demonstration system for non-destructive testing. Endorsement of other codes and standards are foreseen after technical review by the Nuclear and Industrial Safety Agency (NISA) of Japan. This new regulatory process, which utilizes the consensus codes and standards established by academic/public societies, would allow the NISA to accommodate recent technical progress in a more timely manner.

Dissimilar Metal Welds have been widely used at safe-related pressure vessels and piping in Nuclear Power Plants. Some industry codes have been developed for nuclear power plants, such as ASME BPVC volume III & XI, Germany KTA 3201.3 and 3201.4 code and Russia code of light water nuclear power plants. The difference of those codes and some industry feed backs and some experiment results have been briefly introduced and discussed. Furthermore, the inspection qualification or performance demonstration, one of new requirements of some codes, especially for pre-service and inservice inspection of nuclear power plants, really promote continual improvements of DMWs UT both on detection rate and sizing accuracy. Additional, these works really benefit the revision of EJ/T 1039-1996, Non-destructive testing for mechanical components in nuclear island of nuclear power plants, as china building more and more nuclear power plants.

This paper briefly introduces the weld cladding structure, its common defects during the manufacture and operation stage and its application in pressurized water reactor nuclear power plants. Some ultrasonic testing codes or standards for nuclear power plant pressure vessel or piping, such as ASME BPVC volume V & III & XI, Germany KTA 3201.3 and 3201.4 code, France RCC-M and RSE-M code, and Russia code of light water nuclear power plants were discussed. The difference of those codes and some feed backs have been analyzed and discussed. Furthermore, these works really benefit the compiling of NB/T 20003.2-2010, Non-destructive Testing for Mechanical Components in Nuclear Island of Nuclear Power Plants-Part 2: Ultrasonic Testing, as China building more and more nuclear power plants. It was concluded that we shall pay more attention to the inspection of cladding, not only at manufacture stage but in operation outage stage. One of important work is periodically updating the inspection standard revision. It was believed that improving the cladding defects inspection reliability and effectiveness is very important to the safety of nuclear power plants operation in China and in the world.
