Chromel/Alumel thermocouples sheathed with 304L stainless steel and insulated with MgO are integrated to fuel element probes to indicate sodium temperature at the outlets of the fuel channels of the SNR 300. Tests on incorporated thermocouples are reported in this paper. After more than 5000 hours of long term testing at 680 K mean temperature none of 196 thermocouples failed. (auth)
