Radiation induced electrical current and voltage in MI-cables were measured under JMTR irradiation. The negative voltage of about 10V was generated in the center lead. The voltage increased with increasing irradiation dose with about -14V with a total dose of 1.1×1010Gy ionizing irradiation and 1.1×1024n/m2 fast neutron irradiation. The observed electromotive force was a so-called current driven source and the measured current was linearly dependent on the reactor power and was about 50nA for the 0.7m long MI-cables at 573K. Under a reactor full power, irradiation conditions were 6 W/g of a gamma flux(6×103Gy/s ionizing dose rate) for iron and 5×1017n/m2s and 1.1×1018n/m2s fast and thermal neutron fluxes, respectively.
