Absolute calibration of the UNIT-10m setup on the basis of the results obtained by destructive analysis is examined. The calibration procedure consists in performing measurements using the SKAT laboratory test stand at the Radium Institute with a model unirradiated assembly and neutron sources...
The results of multigroup calculations of continuous irradiation of Np, Am, and Cm in VVÉR-1000, PHWR-880, Superphoenix-1200, BREST-1000, and ÉLYaU-800 reactors are used to compare transmutation efficiency. The sources of continuous replenishment for the transmuters were Np, Am, and Cm...
It is often asserted in the literature that a linear dose–effect relation at low ionizing radiation doses overestimates the radiation risk. It is shown by means of a simple mathematical analysis that this assertion is incorrect with respect to an individual source of radiation or chemical...
Epidemiological studies of the consequences of radiation exposure of humans already prove that at low dose rates 85% of radiation-induced cancer arises only above a threshold dose from 0.3 to 30 Sv, and sometimes radiation hormesis occurs. In this question, the ICRP and the RNCRP rely on...
Xenon oscillations – periodic redistribution of the power over the core volume – can occur in a VVÉR-1000 core because of the large size of this core. The xenon oscillations can be conventionally divided into axial, radial, diametral, and azimuthal. In the present paper, methods are...
The energy calibration curve in the α-particle energy range 4.01–8.77 MeV, suitable for solutions of a liquid scintillator with different light absorption, is constructed. The mechanisms of broadening and asymmetry of the α peaks of various actinides are studied. Lists of isotopes, whose...
A complex for remote-controlled contact-free diagnostics systems for performing correlated measurements of the main parameters and characteristics of fast electronuclear and transmutation processes ( t = 1 μsec) in a nuclear-power system is described. The complex contains γ-ray, x-ray, and...
Information about the actual history of cyclic loading in the actual state of the metal in equipment components must be used for analyzing the safety of power-generating units in operating nuclear power plants, in preparation for service-life extension, and to determine the moment of onset of...
