Nuclear power plant design and operation support method and system

Abstract

The invention provides a nuclear power plant design and operation support method and system. The method includes the following steps that: the reactor core of a reactor is designed; three-dimensionalreactor core power distribution information is obtained according to design parameters; a reactor core model is built, the state of the reactor core is monitored and predicted in real time, and the reactor core model is amended according to stages; the calculation model of a spent fuel pool is constructed, so that the critical safety analysis calculation of the spent fuel pool can be performed, and nuclide tracking calculation is performed for an old fuel assembly; a spent fuel transportation container calculation model and a spent fuel storage container calculation model are constructed, so that the critical safety analysis calculation of a spent fuel transportation container and a spent fuel storage container can be performed; a reactor core source item model is built, the analysis and calculation of a primary loop source term and a secondary loop source term are performed, so that source item information can be obtained; and the calculation model of a reactor main shield is built, and ray measurement information in the reactor is calculated according to the calculation model. With the method and system of the invention adopted, design precision and operation reliability can be improved, and therefore, the safety and economy of a nuclear power plant can be improved.

Description

technical field [0001] The invention relates to the technical field of design and operation of nuclear power plants, in particular to a method and system for supporting design and operation of nuclear power plants. Background technique [0002] The traditional reactor design and operation process are separated. During the design process of the reactor, the design institute shall design the core of the reactor according to the parameters of the power plant (such as power demand, overall pressure, etc.), including the design of the core layout and operation mode. During the operation, the operation status of the reactor is monitored through the collection of analog signals (or digital signals), and at the same time, the operator's instructions are converted into corresponding signals and transmitted to the control system, so as to realize the control of the reactor. [0003] With the improvement of digitalization level, more and more automated software analysis systems have b...

Problems solved by technology

[0004] At present, the design and operation of international and domestic nuclear power plants are separated from each other. The parameters designed by the design institute are for operation reference, and the relevant data of the operation process are not fully fed back to the designers.

At the same time, within the nuclear power plant, there is also a lack of data connection between various systems and equipment, and it is necessary to increase the safety margin to ensure the safety of the nuclear power plant, resulting in low design accuracy and design efficiency, poor operational reliability, and high manual error rate.
