摘要： PURPOSE: A boron dilution accident alarming system based on a cumulative sum control chart and a method for the same are provided to prevent the occurrence of accidents by generating alarming sounds. CONSTITUTION: An out of reactor neutron meter(10) detects neutron leaked from a nuclear reactor. A signal processing unit(20) is composed of a preamplifier, an amplifier, and a pulse classifier. The preamplifier supplies high voltages of 1,000V or more to the neutron meter in order to convert electric charge signals into voltage pulse signals. The preamplifier amplifies the voltage pulse signals in order to facilitate a signal processing process. A boron dilution accident alarming system is composed of a digital neutron counting rate converting unit(30), an alarming calculating unit(40), an alarming lamp, and an alarming speaker(50).
