Abstract: The invention relates to nuclear power engineering and is intended for using in power plants with a reactor with a heavy liquid metal coolant (HLMC) based on lead or on lead-bismuth alloys. The invention makes it possible to increase the radiation protection efficiency for the in-vessel equipment of a nuclear reactor, to increase the heat storage capacity of the primary circuit, to reduce the nuclear reactor weight, and to improve its strength characteristics. In the in-vessel space of a nuclear reactor, which is not occupied by the necessary equipment, containers filled with a material that reflects or absorbs neutrons, with a heat capacity greater than that of the coolant, are installed with gaps ensuring the coolant flow, while the containers are placed in such a way that the resulting gaps form channels with a turbulent coolant flow to cool these containers at a flow rate corresponding to the nominal power output level of the nuclear reactor.

Abstract: Threaded connections of casing pipes comprising male and female members with trapezoidal tapered threads arranged on outer and inner surfaces of end sections. Radial sealing surfaces and stop end surfaces contact forming an internal sealing zone. Threads on male and female members have a 1:16 taper ratio, a 23-25° stab flank angle, and a ?3 to ?5° load flank angle. During assembly, crests and stab flanks of thread profile form clearances. Radial sealing surfaces on male and female members are tapered and positioned at a 71-73° angle relative to the normal. Stop end surfaces on male and female members are positioned at a 14-16° angle relative to the normal. Stop end thickness of male member constitutes at least 50% of wall thickness. Tight sealing of connection is preserved under considerable combined loads, including high-torque exposure.

Abstract: The invention relates to a novel ion source, which uses method for the production of highly charged ions in the local ion traps created by an axially symmetric electron beam in the thick magnetic lens. The highly charged ions are produced in the separate local ion traps, which are created as a sequence of the focuses (F1, F2, and F3) of the electron beam (EB) rippled in the magnetic field (B(z)). Since the most acute focus is called the main one, the ion source is classified as main magnetic focus ion source (MaMFIS/T), which can also operate in the trapping regime. The electron current density in the local ion traps can be much greater than that in the case of Brillouin flow. For the ion trap with length of about 1 mm, the average electron current density of up to the order of 100 kA/cm2 can be achieved. Thus it allows one to produce ions in any charge state for all elements of the Periodic Table.
