Abstract

The invention discloses a reactivity meter with an online dynamic scale control-rod worth function and a control method thereof. The reactivity meter comprises a data processor (1) and a signal regulator (2) which are connected through a data wire, wherein an acquisition, processing and communication printed circuit board (9), a rod position signal interface (7), an intermediate zone voltage amplifier (10), a power zone voltage amplifier (11) and an ionization chamber current amplifier (12) are soldered on the printed circuit board (6) of the signal regulator; the rod position signal interface (7), the intermediate zone voltage amplifier (10), the power zone voltage amplifier (11) and the ionization chamber current amplifier (12) are connected with the acquisition, processing and communication printed circuit board (9) through lead wires. The reactivity meter has the beneficial effects that the online-dynamic scale control-rod worth function is achieved, the control rod scale time is greatly compressed, the work complexity is greatly reduced, the dynamic scale control-rod worth method is realized in a metering manner, and standardization and automation of the experimental process are realized.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor measurement devices, in particular to a reactivity meter and a control method with the function of online dynamic calibration of control rod values. Background technique [0002] It is an essential experimental link to pass the calibration control rod value in the reactor physical experiment link after the first start-up and refueling of the reactor. This experimental link is carried out according to the traditional procedures and methods of calibration control rod value. It is a complex operation, Time-consuming and labor-intensive work, in order to improve the efficiency of the physical experiment content and simplify the operational complexity of the experiment, Westinghouse Corporation of the United States proposed an experimental method called "dynamic scale control rod value", which uses pre-calculated static The correction factor and the dynamic correction factor correct the space e...
