[en] A breakthrough in the performance of p-i-n CdTe and CdZnTe detectors is reported. The detector stability has been significantly improved, allowing their use in precise gamma and XRF applications. Detectors with energy resolution close to Si and Ge were produced operating with only -30--35 deg. C cooling (by a Peltier cooler of 15x15x10 mm size and a consumed power less than 5 W). Presently detectors with volume of up to 300 mm³ are available. In terms of photoelectric effect efficiency it corresponds to HPGe detectors with volumes of about 1.5 cm³. The possibilities of further improvement of CdTe and CdZnTe detector characteristics are discussed in this paper

[en] The paper presents the results of the implementation of SFAT for verification of spent fuel at various types of nuclear reactors. The device has been used in those cases where the improved Cherenkov Viewing Device (ICVD) could not provide conclusive results. The paper summarises the experience gained in using SFAT for verification of spent fuel at facilities in Europe. The measurements were performed at Boiling and Pressurised Light Water Reactors of Western design, at WWER-440 and WWER-1000 reactors, and at Research Reactors of MTR type. The experience proved that SFAT can be successfully used for verification of spent fuel. In order to achieve best verification results, the SFAT must be carefully optimised taking into account the fuel assemblies' design features, storing arrangements and irradiation history. (author)
