Title:
POWER DISTRIBUTION MEASUREMENT METHOD, APPARATUS AND SYSTEM FOR NUCLEAR POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2023/184956
Kind Code:
A1
Abstract:
A power distribution measurement method, apparatus and system for a nuclear power plant. The measurement method comprises: acquiring a value of initial reactivity of a reactor when a control rod is adjusted from the inside of a reactor core of the reactor to the top of the reactor core (S100); acquiring a value of final reactivity of the reactor when the control rod is adjusted from the inside of the reactor core to the bottom of the reactor core (S200); and acquiring a radial power distribution of the reactor core by means of the value of the initial reactivity, the value of the final reactivity, and a theoretical power of a control rod assembly corresponding to the control rod (S300). Compared with traditional technology, the method may be used to realize a power distribution measurement of a reactor core in a zero-power physical test platform, thereby improving the accuracy of the power distribution measurement in the zero-power physical test platform.
