I reported a similar runaway with Nano nickel powder at 10nm in my 2012 EPRI 
report.

At ICCF21, JBP was also reporting such runaway event with PdNiZr powder. The 
quantity of PdNiZr was about 100g when the runaway occurred. The runaway 
phenomena stopped when temperature reached ~450°C which is the upper limit for 
this kind of powder. The difference is that the runaway started from room 
temperature. No heat had been feed to the reactor.



The colour of the powder(black) was exactly the same as JPB had after the 
runaway. Normally this powder is metallic grey after deoxidation not black.

My comment:

The sample is ~1 kg. That is much more material than you were using years ago. 
That's good! I am very pleased to see that people are increasing the mass of 
reactant. I believe that is why the level of heat increased. I believe more 
heat comes from a larger number of active sites.

Okay, that may seem like an odd thing to say. It may seem obvious that heat 
will increase as the mass of reactant increases. But I do not think that has 
been tested -- or demonstrated -- up until now. We just assumed that is how it 
works.

Even what we consider obvious aspects of the phenomenon should be tested. It is 
possible that a giant mass of reactant might have no active sites. Or it might 
sinter and stop working.

I am pleased to see larger samples being tested, but that does not mean small 
scale tests such as Beiting and Staker are useless. They do superb calorimetry 
and their signal to noise ratio is high, so there is much to be learned from 
their tests as well. I am glad to see high s/n small-scale tests AND glad to 
see scaled-up tests. Both are valuable.

Note that Staker also reported run-away heat events. I believe they are roughly 
similar in scale to this, when you adjust for the amount of reactant and 
surface area.
