Problems solved by technology

[0002] Although my country has adopted various preventive measures against nuclear power plant accidents, requiring nuclear power plants to strictly abide by operating procedures, and at the same time accept strict supervision by the National Nuclear Safety Administration and other departments, accidents caused by system equipment failures or human errors in nuclear facilities have led to emergency response. extremely unlikely, yet the possibility of an accident at a nuclear facility still exists

Embodiment Construction

[0062] 1. Real-time calculation and correction of operational intervention level

[0063] The real-time calculation of the operational intervention level mainly calculates the values ​​of the operational intervention level OIL1 for evacuation / concealment and the operational intervention level OIL2 for iodine protection (OIL3 to OIL9 do not need to be calculated due to the default values ​​of the International Atomic Energy Agency). The process of real-time calculation of operational intervention level is as follows: figure 1 shown.

[0064] When calculating the operational intervention level, each relevant dose is calculated according to the accident source item and meteorological and environmental monitoring data obtained online, and the value of each OIL is calculated from each relevant dose. Among them, meteorological monitoring data includes wind speed, wind direction, stability, mixed layer height, and precipitation; environmental monitoring data includes effective relea...

Abstract

The invention belongs to the technical field of nuclear accident emergency response, and relates to a nuclear power plant OIL calculation method and a protection action decision system based on the same. The calculation method comprises the following steps: calculating each related dose according to an accident source item and meteorological and environmental monitoring data acquired online, and calculating and correcting each related dose to obtain the value of each OIL. By means of the calculation method for the nuclear power plant OIL, accident source items and meteorological and environmental monitoring data can be obtained online, and OIL calculation and OIL correction are conducted according to the nuclear accident development process. The invention further discloses a protection action decision-making system based on the calculation method. Based on OIL calculation and OIL correction results, data of a plurality of monitoring points can be input at the same time according to related monitoring data of off-site fixed monitoring points, mobile monitoring vehicles and the like, and decision making of public protection actions at different stages is achieved based on the calculation results of the plurality of OIL.

Description

technical field [0001] The invention belongs to the technical field of nuclear accident emergency response, and relates to a calculation method of nuclear power plant OIL and a protection action decision-making system based thereon. Background technique [0002] Although my country has taken various preventive measures against nuclear power plant accidents, requiring nuclear power plants to strictly abide by operating procedures and accept strict supervision from the National Nuclear Safety Administration and other departments, nuclear facilities have caused accidents due to system equipment failures or human errors and caused them to enter emergency situations. The probability of the state is extremely small, however the possibility of an accident at a nuclear facility still exists. [0003] Operation intervention level (OIL) is the intervention level expressed by the results of environmental monitoring, which is equivalent to the measurable amount of radioactivity of the in...
