Summary:In the experimental fast reactor JOYO, an on-line instrumented material irradiation rig has been developed to acquire various irradiation data. Material Testing Rig with Temperature Control (MARICO) is capable of collecting creep rupture strength data for fast reactor fuel cladding materials. The specimen temperature in the MARICO-1 rig is controlled with an accuracy of ±4°C by the use of a gas gap method similar to that of FFTF/MOTA. Presently, irradiation testing using MARICO-1 has been so successful that the development of MARICO-2 is under way for completion by the early part of the next century. MARICO-2 will contain an electrical heater for temperature control, a larger irradiation space and other data collecting improvements.
