A method for assisting with the management of a pumping device capable of supplying a circuit of a power production facility with water taken from a natural watercourse is disclosed here. In particular, at least some parameters relating to a watercourse and having an influence on the quantity of materials liable to clog filters are collected. A statistical model is developed that is at least based on historical data for said parameters relating to the watercourse for which clogging of the filters has been observed. Current parameters relating to at least the watercourse are collected and said statistical model is used in conjunction with said current parameters to assess the risk of an influx of clogging materials, and an alert signal for deactivating the pumping device at a selected time is generated on the basis of the assessed risk.

Managing water-supply pumping for an electricity production plant circuit

A method for determining positions of elements of fuel assemblies arranged in a nuclear vessel is described herein. According to an implementation, the method involves capturing a plurality of images of a nuclear vessel and using the plurality of images to estimate a first set of positions of S-holes of a fuel assembly of the nuclear vessel. The method further involves determining a value representative of differences between: (a) the distances from the estimated set of positions to a location on a face of the fuel assembly and (b) known actual distances between the S-holes and the location on the face of the fuel assembly.
