原子力機構では、自らの原子力施設の廃止措置及び放射性廃棄物の処理・処分を、原子力施設の設置者及び放射性廃棄物の発生者としての責任において計画的かつ効率的に進めていく。研究開発拠点の一つである大洗研究開発センターにおける放射性廃棄物管理について現状を報告する。大洗研究開発センターの廃棄物管理施設では、安全確保を大前提に、契約により大洗地区の原子力事業者から受け入れたものも含め、低レベル放射性廃棄物の廃棄物管理を実施している。固体廃棄物の焼却,圧縮,液体廃棄物の固化等の減容,安定化,廃棄物の保管管理を着実に進め、将来処分まで適切に保管管理している。

By the Japan Atomic Energy Agency (JAEA), designed decommissioning of nuclear facility and the treatment and disposal of radioactive waste will be carried out systematically and efficiently as responsibility as the installer of the nuclear power facility and generator of radioactive waste. This paper shows the present status of radioactive waste management in O-arai Research and Development Center, one of the research and development bases of JAEA. The management of low-level radioactive waste, including those accepted from outside operator of O-arai district, is carried out by the major premise of ensuring safety at O-arai Waste Management Facility. Treatment related to volume reduction and stabilization by means such as incineration and compression of solid waste, and solidification of liquid, as well as waste storage management is steadfastly promoted, so that these substances may be adequately stored and managed until they are disposed of.
