A
concentrated solar power plant comprising a plurality of heliostats or
heliostat field, a substantially cylindrical
solar energy receiver (2), consisting of a
molten salt solar
receiver, located atop a central
tower (1) and having an external surface covered with
receiver panels (8), the heliostats reflecting
solar energy to said external surface of the receiver (2), each receiver panel (8) comprising a plurality of
heat exchanger tubes (9) for transporting a
heat transfer fluid being a
molten salt, which are partly exposed on the external surface of the receiver and comprising a thermo-mechanical
monitoring system to ensure the integrity of the solar receiver panel tubes in different operation phases ; wherein, using the tube emittance ε obtained from the measurements of the external surface of the receiver obtained from the
infrared cameras and the salt temperature in the tubes obtained from the thermocouples during circulation mode, and the atmospheric
transmittance τ obtained from the measurements of the
weather data, the
monitoring system is configured to calibrate the raw temperature measurements Traw acquired by the
infrared cameras (4), so as to obtain calibrated temperatures Tcam.
