OSTI ID:4159723
A thermocouple arrangement was devised for measuring the reactor fuel temperature which achieves accuracy by locating the hot junction within the fuel member rather than in the sheath as in conventional thermocouples. The hot junction and connecting cable are inserted in the fuel member during its fabrication (casting or sintering), and hence they or their outer surfaces must have a higher m.p. than the fuel and not alloy with it: suitable protective coatings for use in conjunction with a U fuel member are Nb and Ta. Conflgurations are given for a U fuel member with a finned Mg alloy sheath and a stainless steel sheathed thermocouple cable which has a Nb covering inside the member. Instructions are given for fabricating the various parts. (D.L.C.)
