METHOD FOR MONITORING AND PROTECTING A PRESSURE WATER NUCLEAR POWER PLANT AND ASSOCIATED NUCLEAR POWER PLANT

摘要

The monitoring and protection method comprises the calculation, from operating parameters of the primary circuit (4) and / or of the secondary circuit (6), respectively for each steam generator (8), of a primary power (P1 ) representative of the thermal power generated by the nuclear reactor and sent to the steam generator (8) via the primary circuit, and of a secondary power (P2) representative of the thermal power extracted from the steam generator (8) by the secondary circuit, and monitoring and protection of the nuclear power plant (2) as a function of the filtered derivative of the difference between the primary power (P1) and the secondary power (P2), of the difference between the primary power (P1) and the secondary power (P2) and / or of an accumulated energy, calculated for each steam generator (8).
