경수형 소형모듈원전 안전조치 이슈 분석

This study analyzes safeguards issues for light water cooled small modular reactors. The modular design of light water cooled small modular reactors, the use of new types of nuclear fuel such as high-assay low-enriched uranium, and various installation environments create new challenges that are difficult to address with existing safeguards frameworks. From safety-security-safeguards perspectives, issues were identified including regulatory asymmetry between exporting and importing countries, long- cycle operation, multi-module operation, and integral design. To address these issues, five approaches are proposed: development of nuclear material diversion scenarios, enhancement of remote monitoring, development of verification techniques suitable for innovative designs, customized spent fuel management plans, and safeguards optimization strategies. These research findings are expected to contribute to establishing a safeguards regulatory framework for light water cooled small modular reactors in the future.
