Bob, You appear to be making the assumption that excess power is being generated within the core. Why would you expect the temperature inside the core to be above the outside of the core unless some extra power is being produced? Why 1200 C when the outside is at only 900 C?
Something does not seem to add up in that calibration run, or perhaps I just missed a fine point that you can help explain. Thanks.

First, Alan was at near maximum power when the reactor tube outside temperature was 900C and the internal core temperature was over 1200C. The Kanthal A1 heater wire would have burned out by the time the reactor tube temperature could have been driven to 1200C, even if Alan could drive it that hard. Parkhomov had a different differential between his tube OD and his core temperature than Alan did. Alan measured his differential curve. If he had gone to 1200C at the reactor tube OD, the heater wire would have been at or above its melting temperature and the core may have been nearly 1400C. It was just not practical. If Alan had the same insulating system as Parkhomov, his reactor tube may have read nearly 1200C while his core was at 1200C. Another reason was the cool-down cycle time. Alan was uncomfortable leaving the system to run un-monitored, so he had to shut it down in a controlled cycle before he fell asleep.

But, suddenly, the experiment stopped. Can you explain that?
