This study aims to to provide a systematic and sustainable strategic direction for road transportation ODA projects in Mozambique to help solve economic bottlenecks and contribute to national and regional economic growth at a time when the country is recovering from the economic shock and cessation of international aid caused by the past "Tuna Bond Scandal" and showing strong commitment to improving the road transportation sector led by the government. Through this, we aim to enhance the effectiveness of Korea's ODA projects and contribute to building a mutually beneficial cooperation model between Mozambique and Korea. Key indicators were established based on literature reviews, and an AHP survey was conducted targeting local road transport officials. The results were utilized to calculate the weights for each indicator and derive the project priorities. The study identified "sustainability" as the most critical factor among the social necessity indicators, highlighting the importance of long-term stability in road transport infrastructure. In the economic necessity category, "cost-effectiveness" emerged as a key priority, emphasizing resource optimization for maximum impact. Within policy necessity, alignment with government development goals was deemed essential for project success. Prioritization of road transport ODA projects based on sustainability, cost-effectiveness, and alignment with government policies is concluded to significantly enhance their impact. By addressing the immediate and long-term needs of Mozambique's transport infrastructure, the proposed strategy ensures resource efficiency and socioeconomic benefits. This approach not only improves the effectiveness of ODA initiatives but also fosters stronger partnerships between donor and recipient countries. Ultimately, the findings contribute to the development of systematic and sustainable ODA strategies for Mozambique.

Currently, radioactive waste for disposal has been restricted to low and intermediate level radioactive waste generated during operation of nuclear power plants, and these radioactive wastes were managed and disposed of the 200 L and 320 L of steel drums. However, it is expected that it will be difficult to manage a large amount of decommissioning waste of the Kori unit 1 with the existing drums and transportation containers. Accordingly, the KORAD is currently developing various and largesized containers for packaging, transportation, and disposal of decommissioning waste. In this study, the radiation exposure doses of workers and the public were evaluated using RADTRAN computational analysis code in case of the domestic onroad transportation of new package and transportation containers under development. The results were compared with the domestic annual dose limit. In addition, the sensitivity of the expected exposure dose according to the change in the leakage rate of radionuclides in the waste packaging was evaluated. As a result of the evaluation, it was confirmed that the exposure dose under normal and accident condition was less than the domestic annual exposure dose limit. However, in the case of a number of loading and unloading operations, working systems should be prepared to reduce the exposure of workers.

경주 중·저준위 방사성폐기물 처분시설의 운영에 따라, 한국원자력연구원(대전)에 임시보관 중인 방사성동위원소폐기물 을 처분시설로 육상운반하였다. 본 연구에서는 방사성동위원소폐기물의 국내육상운반에 따른 작업자 및 일반인에 대한 방 사선 피폭선량을 평가하고 그 결과를 국내 방사선피폭 법적제한치와 비교하였다. 또한 방사성폐기물의 상하차 작업 시 작업 자와 드럼 간 거리 및 방사성핵종 누출율의 변화에 따른 예상피폭선량의 민감도를 분석하였다. 정상 및 사고조건에서의 예 상피폭선량은 국내 법적제한치를 충분히 만족하였음을 확인하였다.
