In order to reduce the cost of plant design and construction, and to enhance the credibility, a study for Three-Dimensional isolation system was permormed. There are two types of isolation system. One is a 3D entire building isolaiton system. The other is a vertical isolation system which is added on the horizontal entire building isolation system. For both systems, outlines of development,requirements of the sytems, process of the verification tests, test results and applicabilities to the fast breeder reactor are mentioned.

Japan Nuclear Cycle Development Institute (JNC) and Japan Atomic Power Company (JAPC) launched joint research programs on structural design and three-dimentional seismic isolation technologies, as a part of the supporting R&D activities for the feasibility studeies on commercialized fast breeder reactor cycle systems. A reserch project by JAPC under the auspices of the Ministry of Economy,Trade, and Industry (METI) with technical support by JNC is included in this joint study. This report contains the results of the reserch on the structural design technology. The reserch is reported in the following orderes, (1) Development till fiscal 2004, (2) Study on the 3-dimentional base isolation system (fiscal 2005), (3) Study on the guideline of 3-dimentional base isolation system, (4) Study on the vertical isolation system for main equiptment (fiscal 2005), (5) Study on the guideline of the vertical isolation system for main equipment.

A research project by JAPC under the auspices of the Ministry of Economy, Trade, and Industry (METI) with technical support by JNC is included in this joint study. This report contains the results of the research on the structural design technology. The research scope was identified as (1) Study on Developing Program, (2) Study on 3-dimentional Entire Building Base Isolation System, and (3) Study on Vertical Isolation System for Main Equipment, and the results of this year's studies are summarized as follows. (1) Study on Developing Program -Performance Requirements for 3-dimensional Isolation Devices "The behavior of a three-dimensional isolated reactor building" and "amenity under the strong wind load" were studied in order to set up performance requirements for the three-dimensional isolation system. Consequently, it was proved for the former subject that the structure of horizontal base-dimensional isolated building was applicable to 3-D isolated building and for the latter that amenity of the operator in the 3-D isolated reactor building is not affected under the strong wind. -Development Targets and Schedules for Three-dimensional Isolation Deviece In order to select the development candidate of the three dimensional isolation devices, "evaluation items and criteria" and "technical guideline on seismic three-dimensional isolation system" were studied. For the former subject, detailed requirements to the component in the reactor building were studied based on the 2002 fiscal year result and embodied.(2) Study on 3-dimentional Entire Building Base Isolation System -The 3 system concepts nominated on 2001, "Hydraulic system", "Fiber reinforced air sp
