IAEA, in preparation for possible commercial operation of small modular reactors (SMR), is pursuing the early development of safeguards approaches for these reactors along with the publication of the safeguards technical report (STR) to make verification activities easier for inspectors. For this purpose, the IAEA, through the MSSP, is developing various approaches for the application of safeguards by design for SMRs in collaboration with five countries that along with the ROK includes Russia, China, and U.S. etc. In order to review the specific design information of the ROK’s only SMR facility, SMART, and to establish safeguards methods from the initial design stage, collaborations were made with the Korea Atomic Energy Research Institute, which researched and developed the SMART. As a result, the design information questionnaire (DIQ) and STR was created and sent to the IAEA. The DIQ is a collection of crucial questions regarding the application of safeguards to understand the characteristics of the reactor facility, and STR is a document referred to by IAEA inspectors during safeguards verification activities. The main contents of the STR consist of introduction, technological description of SMR, safeguards approach, conclusions and annexes. Through this study, it is anticipated to understand the technical requirements for safeguards implementation of SMRs in the design stage, and through the completion of the final report applying SBD with regards to the design of the SMART facility, it could be used as information material for future safeguard verification activities by IAEA inspectors.
