OSCILLATION CONTROL SYSTEM AND PROCEDURE IN THE POWER MARGIN OF NUCLEAR REACTORS.

摘要

TO DETECT THE APPLIANCE OF THE MAGNETIC FLOW AND THE OSCILLATIONS OF THE NEUTRON FLOW IN A LOCATED NUCLEAR ZONE NUCLEAR INDUCED BY THERMO-HYDRAULIC INSTITUTIONS, LOCALORORORAN (LANDING) POWER (REGULATION) RADIALLY IN THE NUCLEUS AND HAVING A SERIES OF VERTICALLY SPACED NEUTRON FLOW DETECTORS, ARE INDIVIDUALLY ASSIGNED TO OPRM ENERGY OSCILLATION CONTROL CELLS (OSCILLATION POWER RANGE MONITORING), DISTRIBUTED ENTRANCE NORMAL GROUPS OF OPRM CELLS ARE TRANSFERRED TO DIFFERENT OPRM CHANNELS, BASED ON THEIR GEOGRAPHICAL SITUATIONS. THE LPRM DETECTOR CHAINS, ASSIGNED TO EACH OPRM UNIT, ARE PROCESSED FOLLOWING A SINGLE ALGORITHMIC CADENCE, TO DETECT THE NEUTRON FLOW OSCILLATIONS AND FOLLOWING THE PRESCRIBED CRITERIA OF FREQUENCY AMPLITUDE APPLIES TO. THE THERMO-HYDRAULIC INSTABILITY CANCELLATION BEGINS, WHEN AT LEAST TWO OPRM DUCTS TRANSFERRED TO SOME GEOGRAPHICALLY ADJACENT UNITS OF OPRM, ARE DISCONNECTED.
