摘要： A hose or tube for transporting a gas specimen has an inner envelope, forming a diffusion barrier and containing a plurality of perforation holes, and an outer envelope, forming a diffusion layer and resting on the inner envelope. The object is to develop a hose or tube so as to ensure transport of a gas specimen over as great a distance as possible without substantial weakening of the concentration, and at the same time without impairing the ability of the gas to be detected to diffuse into the hose or tube. For this purpose, the outer envelope contains diffusion-inhibiting sealing zones on its inner surface, which zones overlap the perforation holes in the inner envelope.

摘要： The present invention relates to a method for detecting temporally varying thermomechanical stresses and/or stress gradients over the wall thickness of metal bodies, in particular pipelines. In the method, the temperature on the outer surface of the body is measured in order to determine a temperature progression and stress progression therefrom. In addition, electromagnetic ultrasonic transducers are used at at least one measuring point on the outer surface in order to determine the progression of the stresses and/or stress gradients over time over the wall thickness of the body in conjunction with the result of the temperature measurement. The method allows the fatigue monitoring of pipelines even in the event of rapid stress changes.

摘要： A method for the quantitative analysis of the composition of a gas mixture is specifically suited for the analysis of the atmosphere of a containment in a nuclear installation. Even under difficult conditions, this method enables the simple, reliable and as direct as possible determination of physical parameters, thereby permitting the characteristic definition of the ignition field and the combustion behavior of the gas mixture. A measuring device is provided with a thermal conductivity detector with a first measuring bridge, a thermal tonality detector with a second measuring bridge, and a common evaluation unit. With reference to bridge voltages present on the two measuring bridges, the hydrogen content and the oxygen content are simultaneously determined in the evaluation unit.

摘要： A container, a device, and a method encapsulate a fuel rod or a fuel rod portion in a gas-tight manner. The container has a hollow cylindrical container part which is closed at the free ends of the container part in a fluid-tight manner by a respective single-piece closure stopper. The closure stopper is provided with a channel that fluidically connects the flushing chamber of the container part to the exterior exclusively in an intermediate position, which is assumed prior to reaching an end position during the assembly process and in which the closure stopper additionally projects out of the container part by an axial length compared to the end position of the closure stopper.

摘要： A method for producing a uranium oxide catalyst body includes the following steps: UO2+x powder, with x≦0.7, having a purity of at least 50% is sintered in a first sintering process to obtain a UO2+y intermediate, where y≦0.25. Then the UO2+y intermediate is oxidized with oxygen and converted in the process into a U3O8−z powder, with z≦1. The U3O8−z powder is pressed to form a blank having a shape that corresponds with the catalyst body to be produced. The blank is sintered in a second sintering process at a temperature of at least 900° C. in an oxygen-containing sintering atmosphere.

摘要： A method for monitoring the fill level of a liquid in a liquid container, in particular for monitoring the coolant fill level in a reactor pressure vessel of a pressurized water reactor system, wherein a determination is made about the drop in the liquid level below the installed height of a heated thermal element by way of the temperature difference measured between said heated thermal element and an unheated thermal element associated therewith, both of said elements being disposed in the liquid container, said method comprising the especially reliable triggering of an alarm with a short response time while maintaining a low level of physical and controls engineering complexity when the liquid level to be monitored falls below a critical value. To this end, according to the invention the temporal progression of the temperature difference is continuously monitored for any significant increase, in particular sudden increase, within a time interval of pre-determined duration prior to the respective evaluation time, wherein an alarm signal is issued as soon as the change in the temperature difference within said time interval reaches or exceeds a pre-determined limit value.
