System code (TPC) survey for the Ar impurity seeding suggested the designed <ne> of 6.6-7.2x1019m-3 was lower than that in ITER. The divertor plasma simulation (SONIC) was performed in the divertor leg length of 1.6 m with the fixed exhaust power to the edge of Pout = 250MW and the total radiation fraction of frad = Prad/Pout = 0.8, as the first step to investigate appropriate design of the divertor size and geometry. Appropriate fuel and Ar puff rates were determined, where Praddiv was ~150MW (fraddiv ~ 0.6), (nAr/ne)SOL was decreased to 0.4-0.45% and nemid was increased to 2.3-2.4x1019m-3. In the outer divertor, the significant radiation peak was maintained in the divertor leg (near the separatrix) at 0.9-1.2 m below the X-point. At the outer target, partial detachment was produced near the strike-point (rdiv < 15 cm), and the peak qtarget at the attached region was ~5 MWm-2. At the inner divertor target, full detachment of ion flux was not produced due to Tediv = Tidiv ~1eV, and the peak qtarget was also ~5 MWm-2 mostly due to the surface-recombination. These results suggest a power exhaust scenario in Demo and the divertor design concept with long leg length, in which the peak-qtarget can be reduced less than 10 MWm-2 for both inner and outer divertor.","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":"22nd International Conference on Plasma Surface Interactions in Controlled Fusion Devices","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":"Asakura, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"656710","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hoshino, Kazuo"}],"nameIdentifiers":[{"nameIdentifier":"656711","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokunaga, Shinsuke"}],"nameIdentifiers":[{"nameIdentifier":"656712","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimizu, Katsuhiro"}],"nameIdentifiers":[{"nameIdentifier":"656713","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uto, Hiroyasu"}],"nameIdentifiers":[{"nameIdentifier":"656714","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kudo, Hironobu"}],"nameIdentifiers":[{"nameIdentifier":"656715","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tobita, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"656716","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noriyashu, Ohno"}],"nameIdentifiers":[{"nameIdentifier":"656717","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"朝倉 伸幸","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656718","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"星野 一生","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656719","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"徳永 晋介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656720","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"清水 勝宏","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656721","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宇藤 裕康","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656722","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"工藤 広信","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656723","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"飛田 健次","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"656724","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":"Simulation Studies of the Divertor Geometry and Plasma Parameters for 1.5 GW Fusion Power Demo Reactor","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simulation Studies of the Divertor Geometry and Plasma Parameters for 1.5 GW Fusion Power Demo Reactor"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-05-01"},"publish_date":"2018-05-01","publish_status":"0","recid":"66798","relation_version_is_last":true,"title":["Simulation Studies of the Divertor Geometry and Plasma Parameters for 1.5 GW Fusion Power Demo Reactor"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:44:47.978360+00:00"}
