The number of units producing radiopharmaceuticals with a half-life of fewer than two hours has increased with the growth of PET technology in Brazil. In the production of such radiopharmaceuticals such as 18F-FDG or 11C-PIB, gaseous waste is formed. The International Atomic Energy Agency (IAEA) proposes a methodology that can be used to evaluate the dispersion of these gaseous effluents. This work has retrospectively evaluated the emission of radioactive gaseous effluents generated in the production of 18F-FDG, in order, to delimit yield values of radioactive waste in the gaseous form and to verify the effectiveness and the design of the safety elements of the exhaust system evaluated before the standards of the National Nuclear Energy Commission (CNEN) and IAEA recommendations. Thirty-six productions of 18F-FDG were found.

Disposal Problem

ABSTRACTAn overview is given of an International Atomic Energy Agency Coordinated Research Project (CRP) on the treatment of irradiated graphite (i-graphite) to meet acceptance criteria for waste disposal. Graphite is a unique radioactive waste stream, with some quarter-million metric tons worldwide eventually needing to be disposed of. The CRP has involved 24 organizations from 10 Member States. Innovative and conventional methods for i-graphite characterization, retrieval, treatment and conditioning technologies have been explored in the course of this work, and offer a range of options for competent authorities in individual Member States to deploy according to local requirements and regulatory conditions.

Official Position

Lithuanian foreign policy perceives International Atomic Energy Agency (IAEA) as an organization with the most significant authority in nuclear safety, capable of assessing Ostrovets NPP's compliance with international nuclear safety standards objectively. Simultaneously, the IAEA is one of the most important international institutions through which Lithuania sought to reveal the shortcomings of the Ostrovets NPP while attempting to legitimize its critical position towards the power plant. Given the relevance of IAEA in Lithuanian foreign policy, the article examines IAEA's public discourse on nuclear energy in Belarus. It aims to assess its role in the process of legitimizing Lithuania's opposition to Ostrovets NPP. After analyzing the IAEA’s leadership statements, the official press releases and the reports published by the peer-review missions during 2007 – 2020, the paper concludes that the IAEA formed a public discourse that exclusively favoured Belarus and significantly contradicted to Lithuania's official position. In this way, the IAEA did not legitimize Lithuania's foreign policy towards Ostrovets NPP. On the contrary, the organization supported nuclear energy development in Belarus. In relation with the findings, the paper provides three suggestions for reshaping the role of IAEA in Lithuanian foreign policy.

ABSTRACTThe global expansion of nuclear energy will generate increasing quantities of waste with low levels of plutonium or other nuclear materials (NM) potentially subject to International Atomic Energy Agency (IAEA) safeguards. Reducing requirements on retained wastes has the potential to reduce future demands on already strained IAEA resources. We describe an effort to help the IAEA and Member States better estimate projected waste loads and associated safeguards obligations by developing a reporting tool to estimate types and sizes of future waste-storage and -disposal facilities. States can use such information to plan waste facilities, including size and type. The IAEA can use these data for inclusion in multiple agency reports and products for the benefit of Member States.

لخلاصة Nuclear energy is among the most important discoveries reached by the human terms contributed to the solution of many problems faced by the states. The last of these that are not only utilizing it in a peaceful area, but tended toward the military field and the nuclear weapons industry , Among these countries, we find North Korea, which has openly declared their manufacture of nuclear weapons and thus entry to the club of nuclear countries. International Atomic Energy Agency has worked to resolve the North Korea standoff but has not been able to achieve positive results, prompting the intervention of European countries in order to end the crisis. تعدُّ الطاقة النووية من بين أهم الاستكشافات التي توصل إليها الإنسان إذ ساهمت في حلِّ العديد من المشاكل التي واجهت الدول . هذه الأخيرة التي لم تكتفي بتوظيفها في المجال السلمي بل اتجهت نحو المجال العسكري وصناعة السلاح النووي .من بين هذه الدول نجد كوريا الشمالية التي أعلنت صراحة صناعتها للسلاح النووي ودخولها بذلك لنادي الدول النووية . عملت الوكالة الدولية للطاقة الذرية على حلِّ أزمة كوريا الشمالية لكنها لم تتمكن من تحقيق نتائج ايجابية ما دفع لتدخل دول أوروبية قصد إنهاء الأزمة. الكلمات المفتاحية : البرنامج النووي ،كوريا الشمالية ، التسلح النووي
