摘要： A fuel assembly for a boiling water reactor has a plurality of fuel rods which are mounted in a plurality of spacers disposed at a spacing distance from each other in the axial direction of the fuel element. At least one of the fuel rods has a reduced length. Deflection elements are arranged at least in the upper region of the fuel element in order to improve the dry-out behavior of the assembly. The fuel assembly further includes measures that reduce a loss of pressure caused in the upper region by the deflecting elements so as to improve thermo-hydraulic stability and the shutdown behavior.

摘要： A fuel element for a nuclear reactor has fuel rods with nuclear fuel guided through spacers. The spacers are equipped with devices that exert a swirling impulse upon a coolant flowing along the fuel rods. In order to present as little flow resistance as possible for the coolant, these swirl-introducing devices have the form of a vane with a spoonlike or bladelike shape and they extend into the coolant flow. Owing to the shape—here the vane is curved in the longitudinal and in the transverse directions—practically all cross sections of the vane have such a high geometrical moment of inertia that even a vane made of a thin sheet metal is sufficiently rigid. Fuel elements configured according to the invention are particularly suitable for use in boiling water nuclear reactors.

摘要： A hydraulic control rod drive for a nuclear reactor, with a a reactor plenum enclosing the drive, comprises first and second hollow bodies together forming a cylinder and a hollow piston. Working fluid is supplied through one of the hollow bodies. The first hollow body is stationary and the second hollow body is disposed coaxially around the first hollow body. The two hollow bodies define an annular gap therebetween so as to allow axial reciprocating movement of the second hollow body, which forms a carrier body for control elements of the control rod. The second hollow body can be lifted, lowered or suspended by feeding working fluid. A portion of the fluid is removed from the inner space via a throttle passage. A positional measurement system determines the relative displacement of the second hollow body by measuring an ultrasonic measurement path. The system includes an ultrasound reflector and an ultrasonic transducer rigidly mounted remote from the ultrasound reflector. Provisions are made for venting the inner space through venting channels which open into the reactor plenum at a security distance from the measurement path so as not to adversely affect the ultrasonic measurement.

摘要： A nuclear reactor includes a pressure vessel enclosing a plenum, a core in the pressure vessel, a pressure-tight encapsulation in the pressure vessel communicating with the plenum, and control members passing through the encapsulation and having first and second control member segments. The second control member segment has an absorber part to be at least partly inserted into and retracted out of the core for controlling reactivity. The first control member segment has an outer drive part. A control drive is associated with the outer drive part for adjusting the control member along the longitudinal direction thereof. An antieject device for restraining ejection of the control member out of the pressure vessel due to a leak at the encapsulation includes a rod coupling having a disengageable coupling catch interconnecting the first and second control member segments and remaining in engagement during normal control motion of the control member and means for unlocking the coupling catch. After disconnection the second control member segment and the absorber part remain in the core for assuming a position fully inserted into the core.

摘要： A method for aligning packet loss priority information for overload control of a data-packet-switching communications device wherein data packets and respectively allocated packet loss priority information are transmitted to the communications device and buffered in relation to a specific connection. The packet loss priority information is then read from the buffered data packets and modified according to the connection type or the application-specific data traffic type. After the data packet has been switched in the communications device, the original packet loss priority information which was switched with the data packets is re-inserted into the corresponding data packet.

摘要： A fuel assembly for a pressurized-water reactor includes fuel rods held in cells of spacers, control rod guide tubes, and a headpiece and a foot piece, by which it is fixed to upper and lower core grids, respectively. A spacer having a first part, which lies on a radially outer side with respect to a longitudinal center axis of the fuel assembly, and a second part, which lies on a radially inner side and is completely surrounded by the first part are included to reduce the size of gaps between fuel assemblies. The second part is formed of Zircaloy. The first part is made of a metallic material, and when compared to the Zircaloy of the second part, has a lower growth in the radial direction, caused by neutron radiation and a higher coefficient of thermal expansion.

摘要： The message cells of a virtual connection appear with a transmission bit rate that is higher in comparison to a transmission bit rate respectively defined for inputs (E1, . . . ,EP) and outputs (A1, . . . ,AP) of an ATM network. These message cells are depacketed. The message signals contained in successive message cells are thereby subdivided into signal sections. Upon attachment of a continuously changing signal section sequence number, these are respectively inserted into the information part of a message cell. The message cells are then transmitted via different transmission routes within the ATM network and are subsequently depacketed. Based on the measure of the signal section sequence numbers contained in these message cells, message signals in the original length are in turn formed from the individual signal sections, these message signals being inserted into message signals of the appertaining virtual connection for forwarding.

摘要： In a method and circuit arrangement for transmitting a continuous bit stream upon involvement of an ATM network, the continuous bit stream appears with a transmission bit rate that is greater than a transmission bit rate respectively defined for inputs (E1, . . . ,En) and outputs (A1, . . . ,An) of the ATM network (KE). This continuous bit stream is subdivided into signal sections that, with respect to their bit plurality plus a defined plurality of information bits, correspond to the plurality of bits transmittable in the information part of a message cell as useful signals. In successive control cycles, a plurality of signal sections corresponding in number to the bit rate ratio of the appertaining transmission bit rates are respectively inserted into the information part of a message cell with a signal section sequence number that continuously varies attached to them. The message cells are then transmitted via different transmission paths within the ATM network and are subsequently joined again to form a continuous bit stream according to the measure of the signal section sequence numbers contained in the message cells.
