Here are the steps I used for live reactor testing this week (pic below).
· Mix six diverse Ni powders in equal portions.
· Place Ni powder in a 99% relative humidity environment for 40 hours.
· Bake Ni powder under vacuum for 6 hours at 250 C.
· Still at 250 C, cycle H2 gas in at 7 psi for 20 min, then pull a vac for 10 minutes. Repeat 8 times.
· Mix fuel: 3g Ni powder, .3g of LAH, .18g of pure Li metal. Stir and then mix using mortar and pestle.
· Put fuel centered in OBE tube and seal off tube ends with Swageloks. Set temp to 110 C and pull vacuum for 1 hour.
· Still at 110 C, cycle H2 gas in at 7 psi for 20 minutes, then pull a vac for 10 minutes. Repeat 6 times.
· Load Ni step-wise using external H2 source for 30 psi, 60 psi, 90 psi, 120 psi, and 150 psi.
· Slowly ramp up coil power over many hours.
· Apply triggers after temperature is stable for coil powers of 600W, 900W, 1340W, and 1600W (for fuel at 847 C, 1036 C, 1215 C, 1330 C).
· Triggers include:
______o Step pressure up and then down and vice versa.
______o At various pressures, apply 20 kV DC over the length of tube interior. (Pressure is high enough to prevent a plasma.)
______o Lower pressure to give a DC plasma with 70W of power in the plasma itself.
______o AC plasma.
______o Vary AC plasma frequency.
______o Step coil power from high to lower and vice versa.
______o Slow AC plasma frequency down and use narrow pulses so that that the plasma will extinguish and then re-ignite every 25 milliseconds. (Waveform pics below.)
______o Sweep AC plasma frequency continuously using various sweep times.
______o Sweep coil frequency continuously using various sweep times.
______o Vary coil drive waveform. Use sine wave at 15 kHz. Later use AC pulses to send current both positive and negative through coil at 500 Hz.
______o Do all of the above trigger tests in various combinations (there are infinite possibilities!)
Results? No excess heat. And nothing above background on Geiger Counter or Neutron Detector.
I have a unique set-up. For example, I can drive the coil or plasma with any arbitrary waveform. I have two amazing amplifiers to do this, and each is driven by an arbitrary waveform generator.
But I have to admit I’m pretty discouraged right now. This is truly like looking for a needle in a haystack. It’s a lot of guessing - and a lot of luck is involved for hitting upon the right combination for all variables. I had high hopes that the plasma would trigger some excess heat.
Given my set-up capabilities - any ideas?
If me356 and the India team working the MFMP are really going to share their steps, maybe it makes more sense to just wait and see what they share before trying more tests.
