The Nickel Sulphate is used to produce Nickel foil in a process described in this article, which is essentially at atmospheric pressure. This nickel foil is then scrunched into balls and one flattened, these are placed at either end of the fuel load in the reactor cores, you can see diagram in this article. Several reactor cores are placed into an array in a sealed chamber the is then evacuated, which you can also see a schematic of in the previously supplied link also. It is our understanding that the TiH2 that is added in to the fuel after processing, is then released into the cores and bleeds out via the 'breathable' Nickel foil plugs into the wider core holding cavity.

It is not known what the pressure is in the main reactor, we know that the distance between the electrodes is 22mm, at the cathode, there is the tip of a thoriated tungsten welding rod penetrating the foil and forming a discharge initiator. Suhas has specifically said in our sound cloud recordings, that the voltage is set so that there is NOT a spark, but a glow discharge - indeed, he says that if there is a spark discharge the core will explode. One might be able to estimate the H2 pressure therefore in the 5mm ID tube, from the 22mm electrode separation and the fact that the 1Mhz DC pulses are applied in the range 2000 - 2400V - presumably, the voltage varies with pressure in some sort of feedback such that no spark is caused. The complication with calculating this is that it is not a simple gas in a tube situation as the fuel is fluidised in it by the attached ultrasonic horn.

We will see if there is a way of getting a precise metric on the H2 either. When asked, he just has a basic vacuum pump and no pressure gauge, perhaps, if we can determine the plumbing, when can put a absolute pressure gauge in the system when we are there after the main testing. This is a good point to have raised, thank you.
