Abstract

Abstract Translated from French Le dispositif comporte des moyens de mesure, d'une part de la puissance neutronique (15), d'autre part de la température du fluide primaire dans la branche froide (1) et dans la branche chaude (1'), des moyens de calcul (2, 4, 6, 8, 12) de la puissance thermique du réacteur à partir desdites mesures de température (1, 1'), des moyens de comparaison (14) du signal de puissance thermique (13) et du signal de puissance neutronique (16) et des moyens de correction (22) du signal de puissance neutronique (16). Le dispositif comporte en outre des moyens de détermination rapide et précise de la puissance secondaire du réacteur par comparaison d'un premier signal de la puissance thermique secondaire (13), établi au moyen desdites mesures de température (1, 1') et d'un deuxième signal de la puisisance thermique (16') établi au moyen d'un bilan thermique secondaire simplifié (25). Application aux centrales nucléaires. The device comprises means for measuring, on the one hand the neutron power (15), on the other hand the temperature of the primary fluid in the cold branch (1) and in the hot branch (1 '), means for calculation (2, 4, 6, 8, 12) of the thermal power of the reactor from said temperature measurements (1, 1 ′), means of comparison (14) of the thermal power signal (13) and the signal of neutron power (16) and means (22) for correcting the neutron power signal (16). The device further comprises means for rapid and precise determination of the secondary power of the reactor by comparison of a first signal of the secondary thermal power (13), established by means of said temperature measurements (1, 1 ') and of a second thermal power signal (16 ') established by means of a simplified secondary thermal balance (25). Application to nuclear power plants.
