Optimal control method aiming at nuclear accident loss and emergency action cost

Abstract

The invention relates to an optimal control method aiming at nuclear accident loss and emergency action cost, belonging to the field of nuclear hazard control. The optimal control method comprises the following steps of: (1) confirming a nuclear accident simulation range; (2) acquiring prediction results of wind filed and turbulent flow of the nuclear accident simulation range; (3) acquiring nuclear accident simulation range data observed by a meteorological observation network at the real time; (4) carrying out assimilation on the prediction results of the field wind and the turbulent flow in the step (2) and the acquired data observed by the meteorological observation network at the real time in the step (3); (5) carrying out diffusion simulation on nuclear accidents; (6) acquiring nuclear accident early-warning information; (7) formulating an optimal control scheme of the nuclear accident loss and the emergency action cost; and (8) providing the optimal control scheme of the nuclear accident loss and the emergency action cost for a commander to make decision. The invention improves the diffusion simulation precision, solves the contradiction between the accident emergency intervention effect and the action cost and improves the solving efficiency of the optimal control problem by more than two magnitude orders.

Description

technical field [0001] The invention relates to an optimization control method for nuclear accident losses and emergency action costs, belonging to the field of nuclear hazard control. Background technique [0002] Since the Chernobyl nuclear accident, the disastrous nature of nuclear accidents has left a deep imprint on the world. At present, the world is not peaceful, and nuclear threats still exist, especially the North Korean nuclear crisis that has attracted the attention of the world many times, posing a potential hazard to my country's national security and people's health. Once a nuclear facility is attacked, it will have serious consequences. As a big country in the nuclear industry, our country is vigorously developing the nuclear industry, and the neighboring countries represented by North Korea are vigorously developing the nuclear industry. The potential nuclear hazards have attracted great attention from the country and all walks of life. Therefore, research ...

Problems solved by technology

This method is relatively mature, but the outstanding problem is that the quasi-hydrostatic model cannot make real forecasts, especially for non-hydrostatic factors and complex thermal processes, and there is often a big difference between the simulated forecast results and the actual situation. Moreover, in order to use real-time observation data as the initial field, the timeliness of the simulation is pursued, resulting in low resolution and sacrificing the accuracy of the simulation again, so it is difficult to meet the actual needs in practical applications.

The vast majority of my country's nuclear power plants are built on the seaside or in mountainous areas, and the meteorological field is controlled by complex dynamic and thermal processes. Using the simulation results of the existing quasi-static model to guide emergency response will inevitably lead to large deviations

In the emergency response to accidents, if the emergency force is invested too much, it will inevitably increase the cost of emergency operations. If the emergency force is invested too little, it will be difficult to reach the intervention target.
