The sturctural materials of the experimental fast reactor, "JOYO", must maintain sufficient mechanical strength during the entire reactor plant lifetime. In JOYO, the material surveillance for reactor structureal components, safety vessel, primary cooling system piping, secondary cooling system piping and tank have been planned to confirem the design integrity of these structures. The material surveillance speciments have been loaded in the reactor plant and they will be periodically taken out and examined during plant life to monitor any changes in mechanical properites. This report summarizes the material surveillance program of JOYO.
