If by "Arnie" you mean Arnie Gunderson; I would agree.
Arnie Gunderson is TOTALLY CLUELESS on these issues.
Arnie attempted to tell the world that the mushroom cloud of the Fukushima Unit 3 explosion was caused by a nuclear explosion that had to have occurred in the bottom of the empty spent fuel storage pool so that the side walls of the empty pool could channel the explosion upwards resulting in the upward rising stem of the mushroom cloud.
We know that the Unit 3 explosion was NOT nuclear; the fuel is too dilute for that, and the Comprehensive Test Ban Treaty Organization confirms that the signature of the released radionuclides match a reactor accident and not a nuclear explosion.
The mushroom cloud and rising stem of ANY explosion, nuclear or otherwise, is due to Raleigh-Taylor instability of the hot low density explosion supporting a more dense column of air above it. There's no need for any vertical walls of a deep pool to focus the explosion upwards. Look at all the mushroom clouds caused by atmospheric nuclear testing in the Nevada desert with the bomb up on a tower. There were no pools with steep vertical sides to form mushroom clouds, and those explosions formed mushroom clouds perfectly.
FBaggins also posted pictures of Fukushima spent fuel assemblies in a water-filled pool after the accident.
If you hear / read anything from Arnie; your best bet is to assume that whatever he tells you is WRONG!
