摘要： A method for the surface tribological decontamination of nuclear fuel rods automates surface wiping by one or more bands of fabric. The band is distant from the axis of the rod, the rod is placed facing the band, and then the band is tensioned around the surface of the rod and moved. The rod may be immobile, moved in pure translation along its axis or with a wide-step helical movement. Preferably, the decontamination is carried by two bands simultaneously, so as to cover the total surface in one pass of the rod.

摘要： The method includes receiving parameters input by a user and calculating crack behavior estimations based on the received parameters by using a plurality of accessible crack behavior models. The crack behavior estimations calculated from each of the models are displayed to the user in order to illustrate how the different models compare in calculating a desired crack behavior profile. The displayed crack behavior estimations utilize a compilation of both historical crack growth rate data, as well as predicted crack growth rate data, and may be displayed as an estimated crack growth rate versus time, or as estimated crack growth over time. These parameters are displayed graphically for each crack behavior model in order to enable the user to make a comparison for each crack growth model.

摘要： The measurement device comprises a real-time measurement-signal acquisition module (25) and means (23, 24) for connecting the cables for picking up the voltage from electrical windings for measuring the movement of the control rods to the acquisition module (25), in order to deliver, to the acquisition module (25), voltage signals corresponding to the voltage induced in the windings while the control rods are being dropped. The signal acquisition module (25) is thus permanently connected to the voltage-signal pickup cables (29) and the signals relating to the set of nuclear reactor control rods may be recorded simultaneously. Means (26, 27) for using the voltage signals delivered by the acquisition system (25) allow the drop times of the control rods to be determined.

摘要： A transiently unstable state of a boiling-water reactor is damped by measuring the oscillating neutron flux and, after a first threshold value is exceeded over a plurality of oscillation periods, the rate of increase of the oscillation is determined. Depending on the slope of the increase, and after a further threshold value (in particular one dependent on the rate of increase) for the oscillating flux is exceeded, a selection is made which one of various stabilization strategies for damping the oscillation should be triggered before a SCRAM becomes necessary. A hierarchy of stabilization strategies is available: blocking a power increase, for instance, in the control system, controlled slow reduction of the power, or rapid power reduction by a "partial SCRAM". The monitoring of the unstable state is effected with a system of sensors strategically distributed throughout the core and which redundantly measure the flux in one region of the core. The sensors act on a plurality of redundantly operating systems, and the signal from each sensor is effective in only one of the redundant systems.

摘要： The girth welds joining the end plugs and the hollow tubes of nuclear fuel rods are inspected automatically using a technique that averages reflectance values, compares the reflectance values to standards defined as proportions of the average, and counts adjacent pixels outside the standards to analyze for defects exceeding a minimum defect size. The minimum defect size is checked by counting the adjacent pixels in mutually perpendicular directions, such as rows and columns in the collected matrix of pixel data. The maximum count in the two directions can be different, for profiling the maximum acceptable defect as to the direction of its extension relative to the tube and/or weld. Tubes are inspected prior to surface treatments that may conceal defects. The tube is fed, illuminated and rotated for at least one revolution at an inspection station, collecting line scans at regular angles synchronously with rotation using a line scan camera coupled to a digitizer to obtain the matrix of data encompassing the girth weld. A numerical processor averages, compares and counts the number of adjacent pixels for assessing weld quality.
摘要翻译：使用平均反射率值的技术自动检查连接末端插头和核燃料棒的中空管的环形焊缝，将反射率值与定义为平均值比例的标准进行比较，并计算标准外的相邻像素以分析缺陷超过最小缺陷尺寸。通过对所收集的像素数据矩阵中的相邻垂直方向（例如行和列）进行计数来检查最小缺陷尺寸。两个方向上的最大计数可以不同，用于对其相对于管和/或焊缝的延伸方向的最大可接受的缺陷进行分析。在表面处理之前检查管子可能会隐藏缺陷。管被馈送，照明并在检查站旋转至少一圈，使用耦合到数字化仪的线扫描照相机与旋转同步地以规则的角度收集线扫描，以获得围绕环形焊缝的数据矩阵。数值处理器平均，比较和计数用于评估焊接质量的相邻像素数。
