A study on maintenance optimization by the automatic planning tool for regular plant outage work in nuclear power plant using the logic programming language 'Prolog'

This paper discusses maintenance optimization by the automatic planning tool for regular plant outage work in nuclear power plant using the logic programming language 'Prolog'. As a result of consideration, the following results were obtained. (1) The automatic planning tool for regular plant outage in nuclear power plant was developed. (2) Using this tool, the work plan for BWR primary recirculation system and residual heat removal system was automatically made on the condition of flattening man loading over the plant outage schedule as much as possible. (3) Several points for improving the developed tool were listed. (author)
