In the method of the invention first and second zones (50, 58) of the surface to be characterised are scanned simultaneously, and first and second photosensitive surfaces (56, 62), different from one another, acquire images of the infrared radiation emitted by said two zones.

A method for encapsulating a fuel rod or a fuel rod section in a container includes inserting the fuel rod or fuel rod section into the container. One of the ends of the container is connected to a purging-gas line. The container is dehydrated and purged by use of a purging gas. The ends of the container are connected to a bypass line in such a way that a closed gas circuit is produced and a hot gas is circulated in the gas circuit until the absolute moisture content reaches an end value at which the absolute moisture content no longer rises. The container is disconnected from the gas circuit and subsequently the container is closed in a fluid-tight manner at both ends.

A movement system for moving a dry shielded canister includes a stabilization portion, and a canister support portion engaged with the stabilization portion and configured for translational movement between an extended position and a retracted position, the canister support portion including a roller interface for supporting and moving a canister. A method of moving a dry shielded canister includes moving a canister support portion engaged with the stabilization portion from a retracted positon to an extended position; moving the roller interface from a retracted position to an extended position to engage with the canister; and moving the canister.

The invention relates to a method for testing a workpiece (2) using ultrasound in a curved region (6) of the surface (4) of said workpiece, having the following steps: (a) a plurality of ultrasonic signals (14a, b) are emitted from a plurality of transmitting positions (Pa-f) at different pivot angles (Sa, b) in a pivoting range (16a, b) with the aid of at least one ultrasonic transducer (10a-f) and are injected into the workpiece (2), (b) a corresponding ultrasonic echo signal (18a, b) is received for each ultrasonic signal (14a, b), and the amplitude of the ultrasonic echo (E) produced upon entering the workpiece (2) or on the rear wall of the workpiece (2) is determined, (c) the ultrasonic echoes (E) having amplitudes representing local maxima are determined for each transmitting position (Pa-f), (d1) if an individual ultrasonic echo (E) having an amplitude representing a local maximum was determined for a transmitting position (Pa-f) in step (c), the associated ultrasonic echo signal (18a, b) of said echo is selected, (d2) if a plurality of ultrasonic echoes (E) having an amplitude representing a local maximum were determined for a transmitting position (Pa-f) in step (c) or if this is predefined for a transmitting position (Pa-f), ultrasonic echo signals (18a, b) are selected if only an individual ultrasonic echo (E) having an amplitude representing a local maximum was determined for an adjacent transmitting position (Pa-f) in step (c) by selecting those ultrasonic echo signals (18a, b) which are in a particular angle range (24) around the corresponding pivot angle (Sa,b) of the ultrasonic echo signal (18a, b) having the maximum amplitude of the ultrasonic echo (E) of the adjacent transmitting position (Pa-f) and which have an ultrasonic echo (E) having a maximum amplitude, (e) at least the selected ultrasonic echo signals (18a, b) are evaluated.

A cooling element (2) for cooling the coolant in a fuel element pond (115) in which a fuel element frame (92) is arranged for receiving fuel elements (98), wherein the cooling element (2) comprises a heat exchanger (64) which is designed for connection to a cooling circuit (120), and the cooling element should be integrated in a space-saving way in an already present fuel element pond (115). According to the invention, the cooling element (2) is dimensioned and configured in such a way that it can be arranged and/or fixed in an unoccupied position (106) for a fuel element (98) in the fuel element frame (92).

To manufacture shaped bodies (10) filled with powder (22) for introduction into the reactor core of a commercial nuclear power reactor a plate made of a metal and/or metalloid is provided with one or more blind holes (14), the blind holes (14) are filled with powder (22), the blind holes (14) filled with powder (22) are reversibly sealed and shaped bodies are cut from the plate so that each blind hole (14) filled with powder (22) is surrounded by a shell made of a metal or metalloid. The powder-filled shaped bodies (10) are used in a ball measuring system for commercial nuclear power reactors and/or for the generation of radionuclides in said reactors.

Hydrogen Mobility Europe 2 (H2ME 2) brings together action in 8 European countries to address the innovations required to make the hydrogen mobility sector truly ready for market. The project will perform a large-scale market test of hydrogen refuelling infrastructure, passenger and commercial fuel cell electric vehicles operated in real-world customer applications and demonstrate the system benefits generated by using electrolytic hydrogen solutions in grid operations. H2ME 2 will increase the participation of European manufacturers into the hydrogen sector, and demonstrate new vehicles across a range of platforms, with increased choice: new cars (Honda, and Daimler), new vans (range extended vehicles from Renault/Symbio and Renault/Nissan/Intelligent Energy) and a new medium sized urban delivery truck (Renault Trucks/Symbio). H2ME 2 develops an attractive proposition around range extended vehicles and supports a major roll-out of 1,000 of these vehicles to customers in France, Germany, Scandinavia and the UK. 1,230 new hydrogen fuelled vehicles will be deployed in total, trebling the existing fuel cell fleet in Europe. H2ME 2 will establish the conditions under which electrolytic refuelling stations can play a beneficial role in the energy system, and demonstrate the acquisition of real revenues from provision of energy services for aggregated electrolyser-HRS systems at a MW scale in both the UK and France. This has the further implication of demonstrating viable opportunities for reducing the cost of hydrogen at the nozzle by providing valuable energy services without disrupting refuelling operations. H2ME 2 will test 20 new HRS rigorously at high level of utilisation using the large vehicle deployment. The loading of stations by the end of the project is expected to average 20% of their daily fuelling capacity, with some stations exceeding 50% or more. This will test the HRS to a much greater extent than has been the case in previous projects.
