Emergency action level (EAL) development is an important tool of emergency decision-making support; EAL is an important basis for emergency response of reprocessing plants. The method recommended by DOE to determine EAL is emergency planning hazards assessment (EPHA). Based on the EPHA methodology, development method of EAL for a reprocessing plant was proposed and then the method was applied and the results were analyzed and utilized. Based on the EAL matrix of a reprocessing plant, an EAL code was designed, programmed and tested. Design of the code mainly includes data grouping, flowchart drawing, frame layer design and presentation layer design. Specifically, data was grouped into 25 groups based on the actual acquisition of data and requirements of judgments for EALs, and flowcharts includes the main flowchart, the automatic judgment flowchart and the manual judgment flowchart. The core judgment module of code for emergency action level in a reprocessing plant was coded by FORTRAN language, and the user interface was developed by Java language. EALs could be determined by relevant characteristic data. Tests are divided into internal tests of the functional module and third-party independent tests. The present results show that the code is exact and reliable, and then the code could be an important auxiliary tool for emergency preparedness and response.
