I believe there maybe an error in this pressure estimate and that the
calculated pressure will be exactly half of 19,861 psi (i.e., 9,930.5 psi).
Although 0.0141 moles of Hydrogen are released, 0.00706 moles of Hydrogen
Gas (H2) are released. I don't believe that free H atoms/ions contribute
I wonder to what extent the temperature gradient could have been a factor
in the failure with one end of the tube being much cooler (the part that is
outside of the heating element with the compression fitting on it).
Perhaps this would reduce the amount of pressure the alumina could contain?

For some of the deviations, there was no good excuse. For some, there is
good reason. MFMP has had difficulty replicating the Parkhomov seals, and
does not yet have the right size alumina parts for proper Parkhomov
replication. And in the Parkhomov design, it is hard to tell if the seal

I would say that the thermal gradients are important in the stress profile of
the tube and could easily lead to failure in combination with the pressure.
The alumina has some mechanical properties, including fracture toughness, since
it is not an jnfinitely ducctile material. Small defects
I think the failure was caused by a brittle fracture of the alumina tube due to
thermal stresses, internal micro stresses caused by micro bubble formation and
resulting embrittlement.

The holding tank for the fuel rods is filled with borated water. The
neutron-boron reaction produces fast ions, which thermalize by knocking
electrons free from water molecules – as does the other isotope decay reactions

Although hydrogen is released from metal hydrides at rates which increase with
increasing temperature– the fallacy of a few of these calculations is that the
release is also pressure dependent; and thus the release will slow or stop at
high pressure. Therefore the release is self-regulating.

The Cherenkov radiation I have seen is primarily blue. It is associated with
the high energy particles emitted from spent fuel in a water storage pool and I
think is associated with the slowing down of the particles in water, as you
suggest. I also think it is associated with the

Hi,
The bursting pressure of a pipe/tube is related to diameter, wall thickness, and
tensile strength, not just the last.

at the time of failure.
Bob Greenyer comments that on the last 2 MFMP experiments, the resulting
sintered Ni + Li, Al mass slid out of the alumina tube with no apparent
sticking/sintering to the alumina. Thus, a reactor that is safely
open-able after the reaction provides opportunity to sample the ash, and

Because the events of 2:29 to 2:30 include a clear mechanical displacement

The video frame of the BANG has 3 different video streams merged into
