It is premature to assume that the explosion was caused by the Rossi effect. The temperature was rising smoothly a few seconds before it occurred, but there seemed to be some indication of a very rapid rise immediately before everything went haywire.
According to my simulations this might be due to this system acting like a type 2 or 3 positive thermal feedback device. In that case, the temperature inside the core would have passed the threshold where the negative resistance region begins. Once entered, the internal temperature will rapidly rise as additional heat energy is released at an ever increasing rate. This rapid rise will not cease until the device self destructs or, if they happen to be fortunate, reaches a temperature at which the heat energy escapes at a rate that exceeds its production rate. The geometry of the test device is the main variable that can be used to solve this problem properly. Of course, if the amount of fuel is reduced, the overall system can be reduced to type 1 operation. In that case there is no negative resistance region and any desired operating temperature can be established by adjusting the input drive level. I believe that it is important to establish exactly what caused the failure before anyone knows how to best proceed. If the cause can not be accurately determined, then it would be prudent to reduce the amount of core fuel to ensure type 1 behavior. We can generally obtain useful data from a system that remains in operation throughout the test procedure.

And I use that term specifically since one also sees some hint of a pressure release. Whether that release is at an appropriate level is apparently debatable... -mark iverson -----Original Message----- From: Orionworks - Steven Vincent Johnson [mailto:[email protected]] Sent: Friday, February 06, 2015 9:25 AM To: [email protected] Subject: RE: [Vo]:Dog Bone Project Good show, Thanks, Craig.
