Abstract

Experiments with cables and wires in the BR2 reactor subjected to well defined thermal gradients show significant thermoelectrically induced voltages between the cable core ends, that evolve consistently with neutron fluence. For all copper based systems, the nearly linear evolution is due to partial transmutation to nickel, while for stainless steel based systems the thermoelectric sensitivity saturates quickly to a value which depends on the local temperature.
