Lead-based fast reactor control system and method

Abstract

The invention relates to a lead-based fast reactor control system and method. The lead-based fast reactor control system comprises a measuring device, a control device connected with the measuring device, a control rod driving mechanism and a main pump, wherein the measuring device is used for measuring operation parameters of a primary loop system and operation parameters of a secondary loop system of a lead-based fast reactor and outputting primary loop parameter information and secondary loop parameter information; the control device carries out calculation processing according to the first loop parameter information and the second loop parameter information and outputs a control rod speed control signal and / or a main pump rotating speed control signal; the control rod driving mechanism controls the speed of the control rod according to the control rod speed control signal; and / or the main pump adjusts the rotating speed of the main pump according to the main pump rotating speed control signal. According to the invention, the position of a control rod in a reactor core and the rotating speed of the main pump are dynamically adjusted according to the primary loop parameter information, so the power and temperature of a primary loop rapidly reach target values, the operation flexibility of the reactor is effectively improved, a transient response requirement when the load is greatly and rapidly changed can be met, and transient response capability is good.

Description

technical field [0001] The invention relates to the field of control of lead-based fast reactors in nuclear power plants, and more specifically relates to a control system and method for lead-based fast reactors. Background technique [0002] At present, there are mainly two control modes for the control of lead-based reactors in nuclear power plants: one is the machine-to-reactor control mode, that is, the core power is adjusted through the control rods to make it reach the target core power, and according to the temperature of the primary circuit, The power response controls the load of the secondary circuit, but the flexibility of operation is limited, and it cannot respond according to the load demand of the secondary circuit. power and temperature, but has limited ability to handle transients with large and rapid load changes. [0003] It can be seen from this that the current control modes of lead-based fast reactors exist: the reactor has poor operational flexibility...

[0002] At present, there are mainly two control modes for the control of lead-based reactors in nuclear power plants: one is the machine-to-reactor control mode, that is, the core power is adjusted through the control rods to achieve the target core power, and according to the temperature of the primary circuit, The power response controls the load of the secondary circuit, but the flexibility of operation is limited, and it cannot respond according to the load demand of the secondary circuit; the second is to adopt the control mode of the stacker, and adjust the control rod according to the load demand of the secondary circuit, thereby adjusting the load of the primary circuit. power and temperature, but limited ability to handle transients with large and rapid load changes

[0003] It can be seen from this that the current control mode of lead-based fast reactors exists: the reactor has poor operational flexibility and poor transient response capability when the load changes rapidly.
