Problems solved by technology

[0003] Because the refueling site of the sodium-cooled experimental fast reactor is invisible and there are many equipments, the operation steps are complicated by operating a single device, which increases the failure rate of human factors and reduces the safety and reliability of refueling
Due to the complexity of refueling, the refueling time is prolonged. For commercial power stations, the longer the refueling time, the loss of economic benefits

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The main refueling equipment of the sodium-cooled fast reactor includes: cock, refueling machine, loading and unloading hoist, transfer room transfer machine, cleaning room transfer machine, transfer barrel, airlock, etc. Through the cooperative movement of the above-mentioned equipment, the transportation of various components from the inside of the pile to the outside of the pile is completed. The refueling process is as follows:

[0022] 1) Use the transfer machine in the transfer room to transport the new components to the bucket of the loading hoist through the conversion barrel, air lock and other equipment;

[0023] 2) The new components that have been loaded into the bucket of the loading hoist are transported to the lower position in the stack by the loading hoist, and finally transported to the designated position in the stack by the...

Abstract

The invention relates to a sodium-cooled fast reactor fuel exchange control technology, in particular to a sodium-cooled fast reactor full-automatic fuel exchange control method and control system. The method adopts a stepwise and parallel method; a total fuel exchange control process is decomposed into four sub processes which are executed in sequence; the sub processes comprise two parallel equipment moving paths inside and outside a reactor; each path comprises a plurality of fuel exchange equipment driving nodes; the driving nodes are used for executing the action of single fuel exchange equipment; and through program control of a main control PLC (Programmable Logic Controller) and a single PLC, automatic circulation of the fuel exchange process is achieved. According to the invention, the fast reactor fuel exchange is full-automatically controlled, the utilization rate of the fuel exchange equipment is increased, the module replacing time is reduced, all steps are all automatically processed by the program, and manual interference is not needed in the whole fuel exchanging process.

Description

technical field [0001] The invention relates to a sodium-cooled fast reactor refueling control technology, in particular to a sodium-cooled fast reactor automatic refueling control method and a control system. Background technique [0002] The refueling operation of the sodium-cooled experimental fast reactor must be carried out in an invisible fully enclosed environment, the working temperature is high, and it is a sodium-related operation. The process is complicated, the cycle is long, and there are many involved equipment. Compared with the refueling operation of the pressurized water reactor, there is a huge difference . The entire refueling process adopts a closed method, and the process is relatively complicated. The new fuel process is to put the new fuel into the conversion cylinder, preheat it, and put it into the stack. Positioning, complete the loading operation in the pile. When the spent fuel is discharged from the pile, the spent fuel is cleaned by means of r...
