Radiation induced electrical current and voltage in MI-cables were mea
sured under JMTR irradiation. The negative voltage of about 10V was ge
nerated in the center lead. The voltage increased with increasing irra
diation dose with about -14V with a total dose of 1.1x10(10)Gy ionizin
g irradiation and 1.1x10(24)n/m(2) fast neutron irradiation. The obser
ved electromotive force was a so-called current driven source and tile
measured current was linearly dependent on the reactor power and was
about 50nA for the 0.7m long MT-cables at 573K. Under a reactor full p
ower, irradiation conditions were 6 W/g of a gamma flux(6x10(3)Gy/s io
nizing dose rate) for iron and 5x10(17)n/m(2)s and 1.1x10(18)n/m(2)s f
ast and thermal neutron fluxes, respectively.
