There is no freaking way that the Burevestnik propulsion system was the one being tested. Anyone who thinks that Putin
announced Burevestnik before it was operational is an idiot. If the Burevestnik uses an thermoelectric isotope power source
then there is no particular risk of it blowing up or even catching fire. There have been decades of such "reactors" produced
and how many accidents have you heard of?
The accident indicates that something different was being tested. Something outside the norm and collected data. It seems
that too much heat was generated which was not anticipated. Thermoelectric isotope generators can have their parameters
determined a priori based on the decay rate of the isotope and the energy of the decay products. If they did not have
this information, then they are testing a new concept that may be some sort of partial chain reaction based system. That
is, they are trying to get more power density out of a given weight of the generator. Isotope generators are rather weak.
By partial chain reaction I mean that no runaway melt down can happen, but the generator is more dirty with more than
one daughter product. This is the price you pay for fending off a rogue military axis.
