The preservation techniques of safety research on "Monju" and the next generation Fast Breeder Reactors have been exhibited. The exhibition consists of (1) EMAT, (2) ECT, (3) Laser Processing Head. Both (1) and (2) are the checking techniques for the cracks on nuclear power plants, while (3) is the repairing technique for the heat exchanger. In 2009, these three techniques will have been integrated to be a new probing system. The hybrid optical fiber has been involved in (3), which the project "photo-Medical Valley in JAEA-KANSAI are now developing as a fiber surgery device.
