Study on design method for seismically base isolated FBR plants

概要 （図表や脚注は「報告書全文」に掲載しております）

電力中央研究所で昭和62年度から平成8年度にかけて実施した通産省受託研究「FBR免震システム確証試験」では，FBR免震システム実用化のための技術を確証，整備するとともにFBR実証炉免震設計への反映や国の安全審査に資することを目的として「高速増殖炉免震設計技術指針（案）」を作成した．本指針（案）は第I編「FBR免震システム安全設計方針」，第II編「FBR免震システム設計方針」第III編「FBR免震システム設計法」から構成されている．第I編はFBRの安全設計におけるFBR免震システム固有の安全設計方針（記述内容は義務），第II編はFBR免震設計における免震システムに特有な耐震設計に関する事項（記述内容は義務とされることが多い），第III編はFBR免震設計における実際的な設計，評価手法，計算手法についての記述で，設計マニュアルとしての性格を有している．また，本指針（案）には免震要素特性データ集等の付録が添付されている．

概要 （英文）

CRIEPI conducted "Demonstration test on FBR seismic isolation system" from 1987 to 1996 under contract with Ministry of International Trade and Industry, Japan. In the demonstration test, base isolation technologies are prepared and demonstrated to apply to FBR and the design guidelines are proposed.In this report overall contents of the design guidelines entitled "Design guidelines for seismically base isolated FBR plants" are included.The design guidelines, as a rule, are limited to apply to FBR plants where entire reactor building is isolated in the horizontal direction using laminated rubber bearings as isolators. The design guidelines and its concepts, however, will be useful for the development of similar guidelines for other isolation systems using different type of isolation methods and other nuclear facilities.The design guidelines consist of three parts and appendices. The first part is "Policy for Safety Design of Base Isolated FBR Plants" specifying the principles and the requirements in the planning and the design for the safety of base isolated FBR plants. The second part is "Policy for Seismic Design of Base Isolated FBR" describing the principles and the requirements in the seismic design and the evaluation of safety for base isolated FBR plants.The third part is "Design Methods for Seismic Isolated FBR Plants" detailing the methods, procedures and parameters to be used in the design and the evaluation of safety for base isolated FBR plants. In appendices examples of design procedures for base isolated reactor building and laminated rubber bearings as well as various test data on laminated rubber bearings, etc. are shown.
