A Large Scale Ongoing R&D Project on Three-Dimensional Seismic Isolation for FBR in Japan

FBR is well known as a reactor that breeds the nuclear fuel. As Japan has little nuclear resources in its territory, the technologies those realize Fast Breeder Reactor (abbreviated FBR) have been developed for decades. The results of the development have been demonstrated through the construction and operation of the experimental fast reactor JOYO and the prototype FBR MONJU. In 1999, the R&D to realize the commercialized FBR has started as a national project. In the project, improving the economic competency of the commercialized FBR plant was set as one of the most important objectives as well as enhancing the safety.Copyright © 2002 by ASME
