A Joyo upgrade program named MK-III program was started to develop future FBR in 1987. The main objectives of this program are increasing the capability as an irradiation test bed core and developing innovative FBR technologies.In order to modify the irradiation capability, the core and plant modification program which consists of increasing the neutron flux density of the core, modification of the cooling system, modification of the plant availability factor and upgrading irradiation technologies were decided based on the result s of survey calculations. The licensing work completed in 1995, and all the modification work completed in 2003. JOYO will start rated power operation along with several irradiation tests in 2004. Also the installation and demonstration program of innovative technologies such as Self-actuated shut down system for demonstration FBR and double-walled steam generator for future FBR were investigated.
