Abstract
The present invention relates to the technical field of nuclear power safety, and particularly to a measuring method for risk of a physical protection system. The method comprises the following steps of: dividing functions of the physical protection system, defining basis threat to a nuclear power plant, establishing a simulation model for the nuclear power plant and the physical protection system, and calculating a risk value of the physical protection system according to the formula R = PA x [1- (PI x PN)] x C. The method related to the invention can determine a reliability of the physical protection system used by the nuclear power plant, and update and modify the physical protection system according to the weakest portion of the system to meet the requirements for physical protection of nuclear material and nuclear facility; and meanwhile, centralized management and control of the whole physical protection system can be achieved by establishing the simulation model.
Description
Technical field
The present invention relates to technical field of nuclear power safety, especially a kind of risk Measure of physical protection system.
Background technology
Physical protection system (PPS) is a kind of integrated system integrating personnel, program and equipment, to take precautions against nuclear material stolen, illegally shifted and the people of nuclear facilities played an important role for the aspect such as sabotaging.And along with the development of the technology such as computer network, communication, information fusion, robotization, building structure; the improvement that it may be necessary method, to improve functional, the Stability and dependability of physical protection system, makes it play more effective effect at protection nuclear material and nuclear facilities secure context.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the object of the present invention is to provide the risk Measure of the physical protection system that a kind of step is simple, reliability is high.
To achieve these goals, the present invention adopts following technical scheme:
A risk Measure for physical protection system, it comprises the following steps:
S1, according to the attribute of the subsystem in physical protection system or equipment, physical protection system is divided into detecting function part, delay function part and response function part;
Attribute and the feature of the event body of S2, the inside of attempting to implement to destroy or steal to nuclear facilities or nuclear material according to potential, outside or collusion from both within and without carry out definition datum threat;
S3, according to the inside of nuclear power plant and external environment condition feature, nuclear power plant and physical protection system are carried out to 3D modeling and form realistic model;
S4, measure the risk of physical protection system according to realistic model: in realistic model, implant formula R=P
a× [1-(P
i× P
n)] × C, meanwhile, probability of happening also counts in formula by the probability of happening that assessment detecting function part, delay function part, response function part and benchmark threaten;
In formula: R is the value-at-risk of physical protection system, P
ifor the outage probability value of detecting function part, delay function part or response function part, P
nfor the failure probability value of detecting function part, delay function part or response function part, C is the assessed value of nuclear power plant's loss of assets.
Preferably, the detecting function part in step S1 comprises detecting and warning system and video monitoring system, delay function part comprise each domain entities barrier device of gateway control system and nuclear power plant, response function part comprises security communication system and online patrol system.
Owing to have employed such scheme, the present invention is led to and can be determined that the reliability of the physical protection system that whole nuclear power plant uses is strong and weak according to final obtained value-at-risk, and according to link the weakest in system, upgrading is carried out to physical protection system, the physical protection requirement of nuclear facilities and materials can be met; Meanwhile, the realistic model by setting up then can realize centralized management to whole physical protection system and control.
Embodiment
Below embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The risk Measure of a kind of physical protection system that the present embodiment provides, it comprises the following steps:
S1, according to the attribute of the subsystem in physical protection system or equipment, physical protection system is divided into detecting function part, delay function part and response function part;
Attribute and the feature of the event body of S2, the inside of attempting to implement to destroy or steal to nuclear facilities or nuclear material according to potential, outside or collusion from both within and without carry out definition datum threat, and this step needs the geographical environment residing for syncaryon power plant and national conditions to determine;
S3, according to the inside of nuclear power plant and external environment condition feature, nuclear power plant and physical protection system are carried out to 3D modeling and form realistic model;
S4, measure the risk of physical protection system according to realistic model, that is: in realistic model, implant formula R=P
a× [1-(P
i× P
n)] × C, meanwhile, probability of happening also counts in formula by the probability of happening that assessment detecting function part, delay function part, response function part and benchmark threaten;
In formula: R is the value-at-risk of physical protection system, P
ifor the outage probability value of detecting function part, delay function part or response function part, P
nfor the failure probability value of detecting function part, delay function part or response function part, C is the assessed value of nuclear power plant's loss of assets; Suppose that outage probability and failure probability all belong to response function part, then outage probability value to refer to from path to certain some position the detection probability that adds up, and this was determined by the time leaving response for.
So, can determine that the reliability of the physical protection system that whole nuclear power plant uses is strong and weak according to final obtained value-at-risk, and according to link the weakest in system, upgrading is carried out to physical protection system, the physical protection requirement of nuclear facilities and materials can be met; Meanwhile, the realistic model by setting up then can realize centralized management to whole physical protection system and control.
Further, the detecting and warning system in the physical protection system of nuclear power plant and video monitoring system etc. can be divided into detecting function part, each domain entities barrier device of gateway control system and nuclear power plant etc. be divided into delay function part, security communication system and online patrol system etc. are divided into response function part.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
