Abstract: FIELD: nuclear technology. SUBSTANCE: invention is meant for measurement of flux of neutrons by primary converter based on unit of ionization chambers used in control and protection system of nuclear reactor, critical assembly and other sources of neutrons. Channel arrangement to measure flux of neutrons incorporates primary converter which includes two neutron-sensitive columes with electrically insulated signal electrodes where material with amounts of nuclei n 1  and n 2 <n 1 , emitting charge particles in reaction with neutrons is placed and electron unit having two paths of measurement of rate of reaction pulse count. Their inputs are connected by electric coupling line to individual signal electrodes of sensitive volumes with amounts of nuclei n 1  and n 2  and path of measurement of electric current. In this case χ/D≅n 2 /n 1 = K 2 /K 1 ≅δ•Q•D•N min /(χ•I b ), where   is coefficient of overlapping of linear sections under modes of measurement of rate of reaction pulse count and of electric current; δ is relative deviation of load characteristic from linear one; D = N max /N min  is range of loading of path of measurement of rate of reaction pulse count; N min  is minimal load of path of measurement of rate of reaction pulse count; N max  is maximal load of path of measurement of rate of reaction pulse count; Q is average charge formed by one reaction of nuclide with neutrons in first sensitive colume; I b  is inherent background current in first sensitive volume; K 2 /K 1  is relation of sensitives of second and first columes to neutrons. Input of path of measurement of electric current is connected to signal electrode of first sensitive volume with amount of nuclide n 1 . In compliance with second version of channel arrangement primary converter has third neutron-sensitive volume. Relation α of inherent background current in it to inherent background current of first sensitive volume is less than relation b of their sensitives to neutrons. In this case c/D≅n 2 /n 1 = K 2 /K 1 ≅δ•Q•D•N min /(α•χ•I b ), where   and input of path of measurement of electric current is connected to signal electrode of third neutron-sensitive volume.

Abstract: FIELD: axial-flow turbomachines (gas and steam turbines and compressors) whose blades suffer high temperatures and stresses, as well as corrosion and erosion effect of working media. SUBSTANCE: blade has lock 1, feather 2, inner collar 4, peripheral collar 6, short superenclosures 3 and 5, primarily metal minienclosures , protective coatings, sliding side supports. Short superenclosures 3 and 5 secured to intermediate and peripheral collars, respectively, suffer much lower stresses under action of centrifugal forces of their masses than long monosuperenclosure secured on periphery. Total tensile stresses are also much lower in peripheral part of feather. Stack of minienclosures whose surfaces are covered with protective coatings ensure thermal protection of feather by reducing intensity of heat radiation fluxes, improving heat transfer and convection, thereby reducing temperature of feather metal and of minienclosure materials. Sliding side supports are made in the form of projections on inner surface of superenclosures which increases their bending strength and rigidity.
