Comprehensive check of VVER-1000 FR surface appearance defects

The subjects of relevance to introduction of automatic check of VVER-1000 FR surface appearance defects are treated in the paper. Visual inspection of FR surface condition carried out manually is a subjective method characterized by low efficiency and reliability. As a result of it, either inadmissible defects are not detected or nondefective products are wrongly rejected. The experience of introduction of automatic check complex constructed on the basis of electromagnetic and optical technique for detection of VVER-1000 FR surface appearance defects is presented in the paper. By means of electromagnetic technique, the sectoring of FR surface and determination of coordinates of supposed defective spots are carried out with check efficiency of at least 60 products per hour. The products without defective spots are transferred further along the production line, and FRs with supposed defects are transferred to the area of optical checking, where the depth, opening and length of the detected defect are measured by the preset coordinate on the optic-electronic plant Profile. If the measured parameters are within the process tolerance, FR is considered as accepted, otherwise, FR is transferred to reject isolator. The application of such complex makes it possible to guarantee the complete check of products, as opposed to earlier performed sampling inspection. Moreover, exhausting hand work performed by operator is eliminated; the reliability and objectivity of FR check are improved, thus resulting in improvement of product quality and safety of operation in the reactor.

Keywords: reactor, fuel rod (FR), defect, check.

The intermediate transitions of the vacuum integrated microwave circuits

The problem of the develorment of intermediate microwave transitions of transfer of electromagnetic energy from one layer of the volume integral circuit (IC) to another one has been solved. The method of vertically through microprofiles of IC of the vacuum microwave lerices was developed. The constructions of intermediate microwave trasitions and the variant of the microblock ofstructure of the circuit for the system of backword wave the construction of the logic elements OR-AND as example are shown.

Keywords: constructive, microaprophils, IS, SVCH-transitions are presented.

Standardization: according to the law or to the concepts?

The main issues related to the need for development of the federal law On Standardization are discussed: the role of standardization in the development of economy and society, why the state should regulate the issues of standardization, why we need a special law On Standardization. It is shown that the standards have a direct impact on the economy due to the diffusion of knowledge (information, innovative solutions). The conclusion about the advisability of public policy in the field of standardization on the basis of an system approach that can be provided by special law On Standardization.

Keywords: standardization, diffusion of knowledge, effect of standardization, federal law About standardization.
