A Database Design Method for Numerical Simulation System of Radionuclide Migration and Diffusion

Abstract

The invention discloses a database design method for a numerical simulation system for the migration and diffusion of radionuclides, comprising: S1. Dividing data in the numerical simulation system for migration and diffusion of radionuclides into dictionary data and business data according to user requirements and entity attributes; S2. Create multiple forms in the database with name, code, data type, length, precision and description as headers; S3. Import dictionary data and business data into corresponding forms to form dictionary tables and business tables. Among them, dictionary Tables are associated with business tables. The method provided by the present invention creates a centralized database, which can centrally process more data, classify and optimize the data structure and type, create a table to store the data types and fields of the numerical simulation system for the migration and diffusion of radionuclides in the water environment, and form A faster, more efficient, safer and more accurate database can provide a good data storage and management basis for the numerical simulation software of the migration and diffusion of radionuclides in the water environment.

Description

technical field [0001] The invention relates to the technical field of radionuclide simulation, in particular to a database design method for a numerical simulation system for the migration and diffusion of radionuclide. Background technique [0002] In recent decades, with the rapid development of the nuclear industry and nuclear technology, the establishment of nuclear facilities has gradually increased. However, the discharge of radionuclides during normal operation of nuclear facilities and the leakage of radionuclides in nuclear accidents have always affected the environment. most concerned issues. Among them, the numerical simulation research of radionuclides in the water environment usually uses non-radioactive environmental pollutants instead of radionuclides for numerical simulation research, which lacks professional pertinence. However, the general database design cannot meet the good data storage requirements and management and maintenance requirements required b...
