Fire load assessment method and system of nuclear power plants

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.

[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 quickly grasp information such as changes in fire loads and regional risk levels brought about by related work, and usually need to calculate and search for relevant paper reports / data to make risk judgments, resulting in Approval personnel lack the basis for judgment when approving, which makes the approval difficult and the approval efficiency is not high

In addition, the existing paper-based approval process cannot quickly and effectively count and summarize the completed approval information, and cannot count the total amount of materials stored in the whole plant and the trend of fire risk introduction
