I was interested in how the pressure behaved in the experiment. To my despair, the experiment ended way to soon to see the pressure flatline. The pressure was still going down at the end of the experiment. Parkhomov ran the experiment in his living room for 3 days, Alan Goldwater was concerned about keeping the hot nuclear reactor unattended in his garage overnight while he slept, understandable, it was a long day, he was tired, he wanted to sleep, so the experiment was turned off. There should be some provision made to run an experiment for days without the fear of a house fire interrupting the generation of data.
The experiment could be brought up to high temperature rapidly since we can see the pressure in the reactor react. As long as the pressure is below the tube pressure rating, then get the tube hot fast to save time, then let the pressure fall as it may. Parkhomov can afford to take his time, he is fearless. If an experiment is to be limited to one day, provisions must be made to maximize that time. Alan Goldwater used a ramrod to pack the fuel into the tube, Parkhomov used a long tube with a large volume in the core cavity because he wanted to use Epoxy to seal the cold tube ends. This may be why there is a large pressure difference between the two experiments. Parhomov had a very large reactor volume to work with because of the long tube that was mostly empty whereas Goldwater had hardly any space remaining in the tube that he used. The Goldwater experiment looked nothing like the Parkhomov experiment. The Parkhomov electrical heater was different from Goldwater’s electrical feed. >
