However, the safety margin is too large for the evaluation using a simplified formula in order to evaluate the neutron streaming of a duct with three feeders (each feeder of size 0.126 m × 0.357 m × 2 m) inside a cylindrical duct (0.8 × 2 m in size). Further, a detailed evaluation of neutron streaming of a cylindrical duct with three feeders has not been performed in the facility. In the present study, three-dimensional (3D) neutronics analysis using a real-model of the complex structured duct was performed to assess the safety margin of the simplified formula. It was confirmed that the neutron dose attenuation of the penetrating section in the duct using the simplified formula is approximately one order of magnitude larger than the real-model using the 3D calculation code.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The Ninth International Symposium On Radiation Safety and Detection Technology (ISORD-9)","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"助川篤彦"}],"nameIdentifiers":[{"nameIdentifier":"712973","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"奥野功一"}],"nameIdentifiers":[{"nameIdentifier":"712974","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"助川 篤彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"712975","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Estimation of Neutron Duct Streaming with the feeder for the Power Supply System in the Tokamak Fusion Device Facility ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of Neutron Duct Streaming with the feeder for the Power Supply System in the Tokamak Fusion Device Facility "}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-07-19"},"publish_date":"2017-07-19","publish_status":"0","recid":"72385","relation_version_is_last":true,"title":["Estimation of Neutron Duct Streaming with the feeder for the Power Supply System in the Tokamak Fusion Device Facility "],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:40:25.660274+00:00"}
