Embodiment 1

[0082] This embodiment provides a scenario selection method for comprehensive nuclear power scenario verification, including the following steps:

[0083] Collect characteristic elements related to operating conditions, personnel tasks and error-prone factors in the process of nuclear power plant operation and accidents to form a total set of characteristic elements,

[0084] Collect scenes related to normal operation, operation events and accidents of nuclear power plants to form a scene collection,

[0085] For each scene in the scene set, select the relevant feature elements from the total set of feature elements to form a subset of feature elements corresponding to the scene, and the scene set satisfies: any feature in the total set of feature elements The element is included in at least one of its feature element subsets corresponding to the scene;

[0086] Superimposing multiple scenarios in which the coincidence degree of feature elements in the scenario set is higher ...

Embodiment 2

[0143] This embodiment provides a nuclear power comprehensive scene verification method, continue to refer to figure 1 , including the following steps:

[0144] S1: Use the scenario selection method for nuclear power comprehensive scenario verification in Embodiment 1 to select scenarios;

[0145] S2: Define and describe each scene in the target scene set obtained in step S1 to form a scene description;

[0146] After the scene set is determined according to the method of Embodiment 1, each scene needs to be defined and described. The operating conditions and scenarios suitable for comprehensive scenario verification should be clearly defined, and the scenario details suitable for simulator applications should be formulated. For each scenario, the following information should be defined:

[0147] Description of unit specific initial conditions;

[0148] Incident or accident description (accident overlay);

[0149] Description of important time nodes of the scene;

[0150...

Embodiment 3

[0192] This embodiment provides a scenario selection device corresponding to the selection method of nuclear power comprehensive scenario verification in Embodiment 1, see figure 2 , which includes:

[0193] The first collection module 11 is used to collect characteristic elements related to operating conditions, personnel tasks and error-prone factors in the operation and accident process of the nuclear power plant to form a total set of characteristic elements,

[0194] The second collection module 12 is used to collect scenes related to normal operation, operation events and accidents of the nuclear power plant to form a set of scenes,

[0195] The selection module 13 is used to select, for each scene in the scene set, the feature elements related to it from the total set of feature elements to form a subset of feature elements corresponding to the scene, and the set of scenes satisfies the total set of feature elements. Any feature element in is included in the feature e...

Abstract

The invention provides a scene selection method and device for nuclear power comprehensive scene verification and a nuclear power comprehensive scene verification method and system. The scene selection method comprises the steps of collecting feature elements and a scene set, selecting feature elements related to each scene from a total feature element set, forming feature element subsets corresponding to the feature elements, and on the premise of ensuring that any feature element is contained in the feature element subsets corresponding to at least one scene in the final scene set, superposing the scenes which are high in feature element coincidence degree and apply different accident handling regulations in the scene set, superposing the scenes which are low in feature element coincidence degree in the scene set, and deleting N-1 scenes in N scenes which are high in feature element coincidence degree and apply the same accident handling regulations in the scene set. Therefore, the scene set which meets the selection principle, is fully covered and eliminates redundancy is obtained, and the nuclear power comprehensive scene verification workload is greatly reduced on the premise that it is guaranteed that source data is comprehensive, rigorous and accurate.

Description

technical field [0001] The present invention specifically relates to a scene selection method and device for nuclear power comprehensive scene verification, and a nuclear power comprehensive scene verification method and system. Background technique [0002] Units 5 and 6 of Fuqing Nuclear Power Plant (i.e., Hualong No. 1) are third-generation nuclear power units independently developed by my country. They adopt the currently widely recognized symptom-oriented accident handling strategy (SEOP) system, which is also an important technical feature of advanced nuclear power units. one. For the development of the accident handling procedure of Hualong No. 1, the corresponding development process should be followed, and corresponding verification and confirmation are required at each stage of development to determine the accuracy of the information and / or instructions and whether the accident handling procedure is accurate. Effectively implement and demonstrate that incident hand...
