Human-induced external events are required for site evaluations to obtain site approval for nuclear power plants (NPPs). National regulations for site evaluations require contemporary standards for site safety. The standards in Indonesia, namely, guidelines for determining the site of nuclear reactors, are incomplete and have not accommodated legal and technical developments, so do not meet current regulatory requirements.

This study aims to enhance the standards for human-induced external event aspects to comply with national safety provisions for evaluating NPP sites in Indonesia. Qualitative research methods are employed, including the identification of requirements for human-induced external events in standards, gap analysis of standards against regulation from the Nuclear Energy Regulatory Agency No. 4 of 2018 referring to International Atomic Energy Agency Safety Standards, and follow-up to the action plan, as a recommendation for revision of the standards. Enhancements to the standards include a detailed explanation of evaluation stages, new clauses relevant to human-induced external events, a refined methodology, and a thorough evaluation of potential hazards from various sources. These findings will guide the enhancement of nuclear safety frameworks by integrating international standards. More detailed standards are expected to improve local practices and contribute to global atomic safety initiatives.
