Abstract

The invention is applicable to the technical field of reactor control and protection systems, and provides a parameter calibration method, a device and a system of a nuclear instrument system. The method comprises steps of: obtaining current data of a ionization chamber in the nuclear instrument system; calculating an upper part current and a part lower current according to the current data, wherein the upper part current is a current in an upper half part of the ionization chamber, the lower current is a current in a lower half part of the ionization chamber; according to the upper part current and the lower part current, obtaining a second nuclear instrument system parameter through inverse calculation of a nuclear power calculation formula of the nuclear instrument system, wherein the second nuclear instrument system parameter is a new nuclear instrument system parameter. According to the parameter calibration method, the device and the system of the nuclear instrument system, the parameter giving time is saved, manual reading and data inputting are not needed, the working efficiency is improved, the error risk is reduced, and the unit output capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of reactor control and protection systems, and in particular relates to a nuclear instrument system parameter calibration method, device and terminal equipment. Background technique [0002] After the implementation of the power indicator calibration experiment RPN8 of the extracore nuclear measurement system, the field work needs to make necessary improvements to the current workflow, including the calibration of the flow coefficient and the confirmation of the new G k parameter or RPN parameter of the nuclear instrumentation system. [0003] The current workflow for calibrating the flow coefficient and confirming the RPN parameters of the new GK or nuclear instrument system includes: Borrowing 4 RPN cabinet door keys at the same time, opening and closing the RPN protection cabinet door in important and sensitive areas for 12 consecutive times within 20 minutes of KME thermal equilibrium time (In addition,...
