Jones is right... If the reactor material is transparent to infrared to any degree, the remote temperature sensor would be looking at the temperature somewhere inside the ceramic tube. Since the amount of radiate heat is proportional to the surface area of the radiating body at the air boundary, the temperature measurement would be incompatible with the proper temperature times surface area formula for calculating heat flow.
They should have painted the reactor black or covered it with graphite and calibrated the remote temperature sensors based on a dummy reactor also painted black.
