Problems solved by technology

[0003] At present, the daily fire management tasks of nuclear power plants are heavy, and most domestic nuclear power plant fire management is still in the stage of manual data retrieval, manual evaluation and review, and cumbersome approval
The approval of material and hazardous chemical storage in nuclear power plants is mainly carried out in paper form, which requires a lot of manpower to transfer and approve the paper document process. The efficiency is low, and it is not convenient for specific on-site work.
At the same time, when the personnel in each link are conducting approval, they cannot quick

Embodiment 1

[0046] Embodiment 1 discloses a fire load assessment method of a nuclear power plant, which specifically includes the following steps:

[0047] S1. Establish a combustibles information database of the nuclear power plant, the combustibles information database includes storage area information and combustibles existing in the nuclear power plant associated with each storage area and the corresponding fire load data;

[0048] The storage area includes various power plant fire protection areas, workshops, rooms, etc. The purpose of this step is to sort out and collect the loads in each area of ​​the power plant, conduct on-site surveys and verify data, and timely discover the changes in fire loads after power plant renovations, etc. Get the actual situation of the power plant. Associate the fire load data with information on storage areas such as power plant fire protection areas, workshops, and rooms, and realize database management through an electronic system. As the basic dat...

Embodiment 2

[0077] Based on the same inventive concept, Embodiment 2 discloses a fire load assessment system of a nuclear power plant, including:

[0078] a combustibles information database, the combustibles information database includes storage area information and combustibles existing in the nuclear power plant associated with each storage area and its corresponding fire load data;

[0079] A standardized calorific value database, the standardized calorific value database includes the standardized calorific value data corresponding to the fixed units of each combustible that has already existed in the nuclear power plant and may appear in the future;

[0080] The fire load analysis module is used to synchronously update the information in the combustible information database for each new material put into the nuclear power plant, determine the fire load data of each new material according to the standardized calorific value database, and update the fire load data of each new material i...

Abstract

The invention discloses a fire load assessment method and system of nuclear power plants. The method includes the following steps: S1, building a combustible information database of a nuclear power plant; S2, building a standardized calorific value database of a nuclear power plant; S3, synchronously updating the information of the combustible information database for materials newly added to thenuclear power plant each time, determining the fire load data of the newly added materials each time according to the standardized calorific value database, updating the total fire loads of corresponding storage areas in real time after the materials are newly added each time, and calculating the fire load density, fire duration and maximum temperature of fire of the corresponding storage areas inreal time according to the total fire load after the materials are newly added; and S4, determining the fire load risk criterions suitable for the storage areas after the materials are newly added each time, and assessing and prompting the risk levels of the storage areas under the determined fire load risk criterions after the materials are newly added each time. The method and system are convenient for the statistics and query of fire load data and the approval of power plant material storage, and the functions of online assessment of newly added fire loads can be achieved.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a fire load assessment method of a nuclear power plant. Background technique [0002] Fire is one of the important risks faced by nuclear power plants. The risk is not only an industrial safety risk, but more importantly, it also brings nuclear safety risks. Existing research and operational experience have shown that fires have a significant impact on nuclear safety. [0003] At present, the daily fire management tasks of nuclear power plants are heavy, and most domestic nuclear power plant fire management is still in the stage of manual data retrieval, manual evaluation and review, and cumbersome approval. The approval of material and hazardous chemical storage in nuclear power plants is mainly carried out in paper form, which requires a lot of manpower to transfer and approve the paper document process, which is inefficient and not convenient for specific on-site work. At the sa...
