Assessment of fuel thermocouple decalibration during in ...

Introduction It is known that refractory metal thermocouples, consisting of tungsten-rhenium (W-Re) alloys, exhibit measurable drift during service in a nuclear environ- ment. This behaviour is believed to be caused by com- position changes of the alloys constituting the two legs of the thermocouple as a consequence of nuclear reac- tions.

Tungstène — Wikipédia

Le tungstène possède 35 isotopes connus, de nombre de masse variant entre 158 et 192, ainsi que 11 isomères nucléaires.Parmi ces isotopes, quatre sont stables, 182 W, 183 W, 184 W et 186 W, et ils constituent avec 180 W, un radioisotope à vie très longue (demi-vie de 1,8 × 10 18 années), la totalité du tungstène naturel, dans des proportions variant de 14 à 30 % (0,12 % pour 180 W).

Rhenium - Wikipedia

Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.
