The invention provides a radial arrangement method of fixed detectors for a nuclear reactor core loading 157 fuel assemblies. The method comprises the following steps: determining the fuel assemblies equipped with control rod groups to be fuel assemblies not equipped with the fixed detectors; arranging the fixed detectors from the second row in an interlacing manner; adding the fixed detectors at proper positions or locally adjusting the positions of the fixed detectors; actually measuring state parameter values of the fuel assemblies equipped with the fixed detectors; carrying out interpolating to obtain the state parameter values of all the fuel assemblies in the nuclear reactor core; determining an optimal solution from the fourth series of solutions to be selected by using a statistical tool. The invention further provides the nuclear reactor core which comprises the fixed detectors and loads the 157 fuel assemblies. The radial arrangement method guarantees the precision and the speed of calculation of an on-line reactor core monitoring system, and further improves the economy of the on-line reactor core monitoring system.
Description
technical field [0001] This application relates to the technical field of nuclear reactor measurement and control, in particular to a radial arrangement method for fixed detectors in a nuclear reactor core loaded with 157 fuel assemblies and a nuclear reactor including fixed detectors loaded with 157 fuel assemblies core. Background technique [0002] In order to enhance the operator's understanding of the inside of the reactor, in recent years, the reactor core online monitoring technology has been developed internationally to provide operators with real-time information on three-dimensional core power distribution. On-line monitoring of the three-dimensional power distribution of the reactor can ensure the safety of the reactor and improve the economic benefit of the reactor. [0003] During the operation of the reactor, the reactor core online monitoring system measures the axial and radial power distribution through fixed detectors arranged in the fuel assembly, checks ...
