Expert systems for plant operations training and assistance

The authors describe a project exploring the use of expert systems for plant operations training and assistance. Three computer technologies were reviewed: computer-aided instruction, expert systems, and expert training systems (ETS). Topics discussed include design considerations related to instructional systems development, expert systems, ETS, and nuclear power plant operational decision aids. Eleven enhancements to existing expert systems are suggested. An example was developed using the REALM expert system for emergency action level classification. The example illustrated how modification and application of an existing expert system can be used to meet training needs. Recommendations for future development of expert systems and expert training systems provided.<<ETX>>
