➢ Two or three people have suggested to me that Mizuno's reaction must be unstable because it is exponential and self-heating. I do not think so. But Mizuno and other have suffered runaway reactions in the past which are completely unexplained to this day since they did not leave behind significant activation of materials.. The best rationale for the belief that this design will not runaway is the very low inventory of reactant and/or the fact that the gainful reaction is not nuclear fusion. Not sure if the inventor or anyone else has calculated the inventory when it is operating but it could be as low as a milligram, no? 300 Pa is about .003 atm. D2 gas weighs in at 4 g/mol. By Avogadro's law 1 mole of every gas occupies 22.4 L. For convenience we can guesstimate the volume of the reactor is 2.24 L so that it holds one tenth of a mole. Therefore, the mass of D2 could be as low as .0012 grams during operation. OTOH - a milligram of deuterium would definitely create a runaway if it all fused in a short time… ERGO – one big reason for thinking a runaway will not happen is that nuclear fusion is not the gainful reaction..
