Abstract: Systems and methods for detecting a subscriber permanent identifier (SUPI) from a subscriber concealed identifier (SUCI) include steps of receiving the SUCI that is a representative of user equipment (UE) of interest and that is encrypted; checking association data with the received SUCI to determine a corresponding SUPI, wherein the association data includes a mapping of a plurality of SUCIs to a plurality of SUPIs and is maintained over time based on monitoring messages in a 5G core network; and providing the corresponding SUPI. The steps can further include updating the association data based on monitoring exchanges on both sides of an access and mobility management function (AMF) associated with the 5G core network.

Abstract: The measurement device (3) comprises a metallic body (5) fixed in the wall of a reactor coolant pipe (1). The metallic body (5) is pierced in order to constitute a first channel (8) communicating with the inner volume of the pipe (1) by a plurality of coolant inlet openings (14) and a second channel (12) communicating with the inner volume of the pipe (1) by at least one coolant outlet opening (15) and enclosing the measurement probe (20) in a zone situated between the end of the second channel (12), which end is connected to the first channel (8), and the coolant outlet opening (15). The coolant inlet openings (14) are disposed on one frontal face of the metallic body (5) in the flow direction (6) of the coolant, and the outlet opening (15) is located on an opposite face thereof.

Abstract: Coolant fluid is sampled from a substantially horizontal part of the hot leg (16) of the primary circuit at at least three points (19, 20, 21) distributed at the periphery of a straight section of the hot leg (16), in such a way that at least one of the sampling points, or lower sampling point, is situated beneath the axis (17) of the hot leg (16). The temperature of the coolant water sampled at each of the sampling points (19, 20, 21) is measured at its outlet from the hot leg (16) and the coolant fluid is reintroduced into the hot leg (16) at a point situated in a position substantially diametrically opposite, with respect to one of the lower sampling points (20, 21), on the straight section of the hot leg (16). The sampling devices (19, 20, 21) connected by pipes (24, 25, 26) to a reintroduction element (22) are arranged at the periphery of the hot leg (16).
