“…In Ref. 33, measurements of the E.-N. effect in Alumel up to 0.35 T are shown and it was mentioned that the induced error ͑due to E.-N. effect͒ tends to saturate above 0.3 T and also that the induced error remained constant in the range 0.5 to 2.5 T but no data were shown to support this claim. It is true that the intrinsic magnetic induction B i will saturate but the total magnetic induction B will nevertheless increase further at higher magnetic field strengths.…”

The effect of neutron and gamma irradiation and magnetic fields on temperature sensors has been reviewed for the particular environment of the International Tokamak Experimental Reactor ͑ITER͒. Both Chromel-Alumel and Nicrosil-Nisil thermocouples are expected to be unaffected by neutron irradiation over the entire life time of ITER. Based on the available data, no significant radiation-induced electromotive force effects are to be expected. Magnetic field effects on Chromel-Alumel thermocouples could under certain conditions become important and, in this case, Nicrosil-Nisil thermocouples are recommended. For high temperature measurements (T Ͼ1200°C) in ITER conditions, tungsten-rhenium thermocouples are the most appropriate choice. Resistance thermometers, on the other hand, were found not to be usable in a reactor environment.
