Title:
REACTOR POWER ANALYZER
Document Type and Number:
Japanese Patent JP3219893
Kind Code:
B2
Abstract:
PURPOSE: To widen the frequency range for analyzing and improve analysis accuracy by providing a time information analysis part analyzing the frequency of output signal from a neutron detector continuously for time.
CONSTITUTION: Output signal from a neutron detector 1 is converted in a signal type converter 3 to a signal type capable of digital calculation processing and sent to a digital calculation processor 4 and recorder 7. The processor 4 corrects in calculation the detection efficiency of the detector 1 and the signal conversion characteristic of a measuring means 2 using calculation coefficients and the calculation coefficients are sent to the recorder 6. A multiplier 8 multiplies the signal stored in the recorder 7 by the calculation coefficients stored in the recorder 6 and send the product to a level analyzer 9. By using this multiplication result, the analyzer 9 analyzes the reactor power level fractuation. A time information analyzer 10 performs time continuous frequency analysis of the signal corresponding to the output signal of the detector prior to the calculation processing which is stored in the recorder 7 or the multiplied result of the multiplier 8.
